NS With the help of a thin-walled aluminum profile, it is attached, the walls are insulated and the ceilings are installed. In addition to the well-known PP-type products, there is a wide range of aluminum products that facilitate installation and help save the builders' time, and, accordingly, the customer's money. What is the profile for drywall, sizes and types, photographs and examples of use - in this material.
Profile construction
An experienced and talented craftsman will be able to build a frame from any profiles that he has. There are three main types of aluminum guides that are used for all types of work - these are straight guides PP 50/40, PN 60/27 and PP 27/28. They are intended to create frames with straight surfaces, however, by simple manipulations with their help, they mount curved structures, arches and small architectural forms. However, the work will go easier, and the result will be better if you use specially designed material for each type of work. A profile for drywall, the sizes and types of which are standard, will serve as examples for description.
Frame elements
The PN type guide has a cross-section of 50/40, 75/40 or 100/40 mm. It is used to mark the boundaries of the plasterboard structure, to install and secure the racks - the main structural elements to which the sheathing sheets will be attached. Its shape is flat U-shaped, it usually has pre-drilled 6 and 8 mm holes for fastening, but more often it is supplied without perforation. It is most often made of galvanized steel, so the profile does not corrode. Profiles for drywall types can be very different, but the basis of the frame is always guides.
The PS rack profile is a product that is used in conjunction with the guides described above and has the appropriate section - 50/40, 75/40 or 100/40 mm. It is also made of steel, has a U-shape, but during the rolling process additional stiffeners are squeezed out on it - one at the edges, at least three at the end. The ends of this profile are bent inward, which gives additional rigidity. PN and PS are used for the installation of vertical structures.
- The connecting longitudinal bracket is an element that allows joining and thus lengthening the profile. It is a spring, fastened with self-tapping screws from the sides.
- The plinth strip is a fastening element with which the border of the cladding sheets is indicated from the bottom, top or sides. The outer edge is perforated, that is, it is assumed that the visible part will be putty.
- The hat profile is a special type of profile that can be used without guides, and the fastening is carried out directly to the wall or ceiling. Used as a frame for insulation.
- Z-profile - used as additional stiffeners.
- L-shaped profile - traditionally used as a starting or finishing element in structures with open ends.
Sizes and characteristics
Rails and posts are made of galvanized sheet steel. Whatever the profile for drywall: dimensions and types, its configuration, in any case, the choice of material should be determined by strength requirements. Plasterboard walls and ceilings are suspended structures that are not designed for heavy loads, but they are still possible during operation. A frame made of a profile should ensure, first of all, spatial rigidity, not allow sheathing sheets attached to it to bend and deform.
The thickness of the steel for the posts and rails must be at least 0.4 mm. The carbonaceous profile can be thinner, since it does not experience structural loads. The wider the profile and the longer the unsupported span, the thicker the metal should be. Fasteners are made with a thickness of 0.4 mm.
Useful information! The standard length of the profile is 3 meters, but there are 2.5 guides on sale; 2.8; 4; 4.5 and 6 meters long. If desired, the section of the profile can be lengthened using special connections.

Mount options
Fasteners are intended for the installation of ceilings, since when erecting a wall frame, fastening is carried out using ordinary self-tapping screws at the intersection of the profiles. Special elements serve to give spatial rigidity and to connect parts located at different levels. The types of profiles for drywall can be different, therefore, the fastening in each case is selected individually.
- Hangers are the most common type of fasteners, which is a perforated plate with special notches, which bends and turns into brackets of various configurations. The end of this bracket is attached to the ceiling, and the free ends hold the ceiling profile hanging.
- Corner connections are brackets that allow you to fasten from the end of the profile.
Examples of assemblies and structures
Example 1: the ceiling is ready for cladding, the frame is made and the insulation is made.
Example 2: A complex multi-level ceiling with many curved lines.
Example 3: An alternative connection scheme for plasterboard profiles.
Example 4: classic straight hanger mount.
Example 5: Closed arched profile with increased strength.

Types of profiles for drywall and their purpose: basic classification
Manufacturers offer products in various shapes and sizes. To purchase everything you need to install a specific structure, you need to clearly understand what types of profiles for drywall exist and their purpose. We offer you to get acquainted with the main classification.
Surface-plane profile for drywall
They can be fixed to the ceiling either. Their configuration is standardized, but there are differences in material thickness, length and transverse dimensions of the product itself. They allow you to form a reliable frame for fastening drywall with the correct choice of size and adherence to the installation technology. It is important to remember that the price of a profile for depends on the size and type.
Plasterboard guide profile: distinctive features
Marked with PN (UW). This is the starting profile for. The section is U-shaped. The walls are smooth. Acts as a support for various uprights and lintels. The rest of the structural elements are put on it during the installation process.
The plasterboard guide profile can be of various lengths (up to 4.5 m). The most popular is 3 m. The transverse dimensions are selected individually for a specific system.
Rack profile for drywall: design features
Marked with PS (CW). It is installed inside the rail and is used to fasten other elements of the system. The rack profile for drywall is quite tough. Able to perceive significant construction. Has a U-shaped additional section with additional shelves for fixing other structural elements.
Attention! If the base is flat, the rack mount can be mounted directly to a wall or ceiling.
Plasterboard ceiling profile: main types
It can be a carrier PP (CD) or a directing PPN (UD). Products with a U-shaped cross-section, but with smaller dimensions than the wall, to save space. To increase the rigidity of the plasterboard ceiling profile, additional shelves and ribs are provided.
You can use a special one to fix the elements. Allows you to install a ceiling structure of any shape and size.
Drywall Corner Profile
To strengthen the outer corners of the walls of the plasterboard structure, it is possible to use a perforated corner metal profile. For its manufacture, metal with a thickness of 0.3-0.4 mm is used. The corners are installed on top and covered with a layer of putty.
Partition bearing profile for drywall and photos of finished structures
For the manufacture of drywall partitions, the UW and CW profiles are used. The first one allows you to form the skin of the structure. It is used to form the perimeter of the partition and provide the required configuration.
The CW plasterboard partition profile ensures sufficient rigidity of the system. Fastening of sheets can be performed on both sides.
We offer you to see the photos that you can create:

Arched plasterboard profile
It is characterized by a complex design. It has side slits to provide sufficient flexibility. Additional perforation increases the rigidity of the product.
Allows to form a structure with a radial bend. Most often made of PP 60/27. The standard length of the profile for drywall is 3 m. The minimum bending radius of the concave element is 500 mm.
Auxiliary components of the profile frame for drywall
For the installation of a system of the desired size and shape, special components for drywall may be required, each element has its own specific purpose. You will need a longitudinal connecting bracket if you need to connect the elements.
You may also need to purchase a profile:
- basement to create a limitation around the perimeter of the cladding. The outer side is putty;
- cap for sheet mounting. Attaches to the base. Allows you to abandon the guides;
- L-shaped, if it is necessary to install a finishing or starting bar in a wall with open ends;
- z-shaped to increase the rigidity of the system;
- beacon if the base is to be aligned.
Fasteners
To fix the profile, either dowels are used. They are hammered or twisted at the intersection of adjacent elements. The following can be used as fasteners:
- hangers used during installation. If necessary, they can always be bent to obtain a plate of the desired size;
- crabs with a characteristic cruciform configuration. With their help, you can provide a rigid connection of intersecting strips;
- two-level brackets, relevant when installing a multi-level ceiling;
- corner brackets installed at the ends of structural elements.
Advice! When choosing fasteners, be sure to consider the dimensions of the metal element.
Criteria for choosing a metal profile from drywall
In order for the mounted structure to last long enough, it is necessary to choose the right metal profile for drywall. Attention deserves not only its appearance or size, but also other important points worth paying attention to.
Profile coverage and material thickness
When buying, you should give preference to galvanized products. In this case, it is imperative to check the integrity of the coating.
The thickness of the product deserves special attention. The larger this parameter, the stronger and tougher the metal profile will be and the higher its cost. If the thickness of the element is insufficient during installation and under operational load, it can change its geometry.
Drywall is one of the most popular finishing materials, used not only to add decorativeness to walls and ceilings, but also to create additional interior partitions.
Installation of such sheet elements is quite simple, since it is carried out using special profiles for drywall of various types and sizes.
Let's figure out how to choose the right fastener for each specific situation.
Types and application of profiles for drywall
Elements for fixing gypsum plasterboard sheets are made by cold rolling a long strip, the thickness of which is in the range of 0.55 - 0.8 mm.
One of the most famous manufacturer is Knauf, which creates rolling profiles for buildings for various purposes. The manufacturing process is carried out in strict accordance with the regulatory document TU 111-004-04001508-95.
Depending on the places of application profiles for plasterboard sheets are divided into:
- Ceiling;
- Wall.
There is also classification of metal profiles by purpose:
- For finishing existing wall and ceiling structures;
- For creating new partitions in room.
Like any other frame structure, metal lathing for fastening consists of many different elements... They differ from each other in thickness, bending shape and degree of bearing capacity. Let's take a closer look at each of the types.
Guide rails with UD or PN marking
Based on UD parts the entire subsequent skeleton is created, formed by attaching other elements to them.
It has a significant bearing capacity, which allows the entire system to be kept in the initially specified geometric state, preventing the development of bending deformations inside the lathing.
Often, such parts have a perforated structure, which makes it much easier to attach them to the sheathing structures.
Dimensional quantities:
- Channel height - 27 mm;
- Profile width - 28 mm;
- Standard length and weight - 2.5 m. (1.1 kg), 3 m. (1.2 kg), 4 m. (1.6 kg), 4.5 m. (1.8kg).
Guide parts with UW or PN marking
Applicable for wall structures, as well as the basis for the construction of partitions. The principle of operation is similar to the UD profile, however, they have slightly different geometric characteristics: 
- Channel height - 40 mm;
- Profile width:
- 50 mm;
- 75 mm;
- 100 mm.
- The thickness of the metal part is 0.5-0.6 mm;
- Standard length and weight:
- 2.75m (1.68kg), 3m (1.83kg), 4m (2.44kg), 4.5m (2.75kg);
- 2.75m (2.34kg), 3m (2.55kg) and 4m (3.4kg), 4.5m (3.83kg).
Rack profile CW or PS
Stiffening element of the sheathing, serving to strengthen the entire structure... The installation of the racks is carried out by fixing them in the guide profiles with a step of 400 mm.
Dimensional characteristics:
- Height - 50 mm;
- Profile width:
- 48.8 mm;
- 73.8 mm;
- 98.8mm.
- The thickness of the metal part is 0.5-0.6 mm;
- Standard length and weight:
- 2.75m (2.01kg), 3m (2.19kg) and 4m (2.92kg), 4.5m (3.29kg);
- 2.75m (2.34kg), 3m (2.55kg) and 4m (3.4kg), 4.5m (3.83kg);
- 2.75m (2.67kg), 3m (2.91kg) and 4m (3.88kg), 4.5m (4.37kg).
Carrier CD or PP
As the name implies, this type of wireframe part takes on loads from the entire structure cladding or partitions. In addition to CD (by Knauf), there is a PP marking, which most fully reveals the purpose of such profiles.
PP marking stands for "ceiling profile", that is, these elements can be used not only for wall structures, but also for the ceiling.
Dimensional characteristics:
- Height - 27 mm;
- Profile width - 60 mm;
- The thickness of the metal part is 0.5-0.6 mm;
- Standard length and weight - 2.5 m. (1.65 kg), 3 m. (1.8 kg), 4 m. (2.4 kg), 4.5 m. (2.7kg).
Arched profile
Designed to create curves and arches. It is a kind of CD and UD profile. The main distinguishing feature is significant perforation, as well as the presence of multiple side cuts, allowing the free bending of this metal profile.
Geometric characteristics convex elements:
- Length - 2.6m, 3.1m, 4m.
- Curvature radius:
- 0.5-1 m;
- 1-2 m;
- 2-3 m;
- 3-4 m;
- 4-5 m;
- > 5 m.
For concave elements:
- Length - 2.6m, 3.1m, 4m.
- Curvature radius:
- 1-2 m;
- 2-3 m;
- 3-4 m;
- 4-5 m;
- > 5 m.

Corner PU
Designed for mounting on external structural elements. Protects them from destruction and various kinds of damage during further operation. Corner elements are significantly perforated.
The holes serve for additional bonding between the plaster or putty mortar and the finishing surface.
Dimensional characteristics:
- 25 * 25 * 0.4mm;
- 31 * 31 * 0.5mm;
- 31 * 31 * 0.4mm.
- Profile length - 3 m;
You can also find a plaster corner profile with the following characteristics:
- Length - 3m;
- Cross section - 35 * 35 mm.
Beacon profile PM marking
It is applied for ensuring the best quality of finishing works.
Allows for a more even plastering of the entire surface.
Dimensional characteristics:
- Transverse section:
- 22 * 6mm;
- 23 * 10 mm;
- 62 * 6.6mm.
- Profile length - 3 m.
Additional elements
For the implementation of drywall sheets also you will need the following products:
- Anchor suspension fixing PP profiles to the ceiling. Equipped with a rod and a clamp, with the help of which the gap between the main structure and the drywall sheet is adjusted;
- Direct suspension, with the help of which the profiles with PS and PP markings are fixed to wall and ceiling elements;
- Screws and dowels by which elements are attached to walls and ceilings;
- Crab connector that serves to create integrity between cross-section parts;
- Extension required for joining adjacent strips;
- Connector, which helps to fasten 2 levels of PP profiles.
For the installation of partitions, profiles with the letter W at the end of the marking are used. Metal elements with the letter D are used for the construction of wall frames.
Materials for the manufacture of parts
Details for creating a frame for drywall made of galvanized steel as it has excellent anti-corrosion properties.
Even if the integrity of the zinc coating is damaged, the duo of steel and zinc will create an oxide film that prevents the appearance of rust on the profile elements.
Also the galvanization is excellent resists the influence of moisture, sharp changes in temperature, and is also an absolutely safe material for humans.
Dimensions for plasterboard lathing
Consider the calculations of the geometric dimensions of the lathing using the example of ceiling decoration.
For the installation of a plasterboard ceiling structure you need to purchase 2 types of metal profiles:
- With PP marking;
- With PN marking.
Since PN profiles are guides, their total length should be equal to the perimeter of the room.
Amount is determined by the formula:
N = P / x; where N is the required number of elements (pieces); P is the perimeter of the room, equal to the sum of all its sides; x - the length of one element (most often 3 and 4 meter profiles are found).
To determine the number of PCB parts, you need to decide how they will be installed.
Normal styling
It is characterized by the initial installation of guide elements around the entire perimeter of the room, and then the laying of PP-profiles with a step of 0.6 m (since the width of a standard drywall sheet is 1.2 m, and the PP-profile must be located strictly in the middle of it).
Calculation formula of the required footage of PP-profiles:
L1 = N * B, where L1 is the required number of running meters of PP elements, N is the number of middle elements, determined taking into account the pitch of the structures, B is the length of the room.
It should also be borne in mind that to ensure the normal rigidity characteristics of the plasterboard ceiling, it will be necessary to install transverse parts, the pitch of which should be 0.5 or 0.6 m.
The calculation of the footage is carried out according to the formula:
L2 = N * A, where L2 is the required transverse PP profiles, N is the number of cross-sections determined by their step, A is the width of the room.
The required number of piece PP elements is found by the formula:
L = (L1 + L2) / x, where x is the length of one element (most often 3 or 4 meters).
Complex styling
The calculation of the number of elements is similar to the conventional styling option. However, here you need to take into account that with complicated installation profiles must be located under each of the edges of the drywall.
Also a more frequent step of minor elements will be required(0.3 or 0.4 m). The result is a more powerful lathing that can withstand significant loads.
For a wall and a partition, the calculation is carried out in the same way, only instead of the perimeter of the room, you need to use the perimeter of the vertical wall of the room.
Also, when constructing a wall, the resulting number of elements must be multiplied by 2, since double-sided installation of drywall sheets.

How to choose profiles for a wall structure?
Successful selection of profile elements depends on 3 components:
- The correct choice of the purpose of parts (for a wall, ceiling, partition or arched structure);
- Competently carried out calculation of the required number of elements;
- Parts manufacturer.
We have already figured out how to make the right choice on the first two points, it remains to decide on reliable firm, which manufactures profiles for fixing plasterboard sheets.
Given the reputation in the building materials market, there are 2 most reliable companies:
- Knauf;
- Gyprok.
These German companies have gained their high position due to the consistently excellent quality of materials, as well as strict compliance with all regulatory requirements for the storage and manufacture of materials and products.
In addition to the products of these manufacturers, there are economy analogues, produced in the post-Soviet space.
These include:
- Remax;
- Albes;
- Buddetal;
- Special profile;
- Interprofile;
- Kievmetalloprom;
- NeiCO Manufacturing Ukraine;
- SMC "Stillline" and others.
They are not inferior in quality imported frame profile elements, however, they have a more affordable price.
Construction of a plasterboard or even a partition element requires certain knowledge and skills in this area.
But if you choose the right quality components of the frame, as well as make correct calculations of the number of elements, you can easily build a drywall structure with your own hands.
It is necessary to choose a profile for drywall with great care. To make the right choice, you need to study the features of the profiles, their types and sizes, as well as pay attention to several more important nuances.
Peculiarities
The profile for drywall has a completely transparent purpose - maintaining the entire drywall structure. An ordinary metal profile is not suitable for these purposes. A mandatory requirement is the weight of the structure. It is unacceptable that the profile frame is too heavy. At best, the plasterboard structure will stagger and creak, at worst it will collapse.
It is believed that an experienced craftsman can use any profile while getting an excellent result. This statement is only partly true. Only profiles designed for work with drywall are suitable for the construction. There may not be a profile of the required type at hand, and then an experienced craftsman can remake an unsuitable profile into the desired one.
These metamorphoses are caused by the choice of materials from which the profile samples are made. Flexible metals are used. Most often, galvanized steel constructs are used, but there are also aluminum ones. They are not very popular because they are quite expensive. Steel is much cheaper.
Types and sizes
If a house from a bar, for example, can be built completely without using metal profiles, then in the case of drywall, this luxury is not available. Metal profiles for gypsum boards are produced in a huge variety.
All of them can be divided into two large groups according to the type of attachment point:
- wall-mounted;
- attached to the ceiling.
Depending on the purpose, the classification is as follows:
- profiles used for finishing works;
- options for the design of new partitions.
Each of the subspecies includes many shaped elements that differ in length, thickness and width, the degree of bearing capacity, and bending. Separately, it is worth highlighting the profiles for arches, which are very different due to their shape. Experts even put them in a separate category.
Some of the profiles are interchangeable and can be dispensed with. The use of each specific sample greatly simplifies the work. So, if you do not have enough experience, then it is best not to try to save a lot, but to buy everything you need. If you already have the knowledge and practice in this installation, feel free to experiment.
UD or MON
This type of profile can be safely called the main one. On its basis, the entire frame is mounted due to the high strength characteristics of the product. This metal profile is load-bearing. Reinforced with stiffeners, it can not only have a smooth structure, but also be perforated. By the way, this option is much more convenient, since you do not have to make holes for the screws yourself. If you fix this type of profiles correctly, then the whole structure will be reliable, it will not creak and wobble.
As for the dimensions, the strips of the UD or PN type have the following dimensions: the height of the channel itself is 2.7 cm, the width is 2.8 cm, the thickness varies between 0.5-0.6 mm. The weight depends on the length and is 1.1 kg for profiles with a length of 250 cm and 1.8 kg for a profile of 4.5 m.And also models with a length of 3 m and a weight of 1.2 kg and four-meter models with a weight of 1.6 are produced. kg. Please note that the most popular is the Knauf model with a section of 100x50 mm and a length of 3 m.
UW or Mon
A profile of the guide type, which is used to create all kinds of plasterboard partitions. It attaches to the wall. With its help, a plasterboard sheet is fixed. It is made from a metal strip, the material of which is galvanized steel. In the future, UW or PN is used as a guide for the rack profile.
Interestingly, these profiles are only used in interior furnishings. So, with their help, only interior partitions can be erected.
Despite the similarity with UD or PN, this model has different dimensional characteristics. Here the height of the channel is 4 cm. The width may vary depending on the partition being erected. Available in 50mm, 75mm and 10mm widths. The thickness is the same as that of UD or PN - 0.5-0.6 mm. It is logical that the mass depends not only on the length of the profile, but also on its width: a 5x275 cm profile weighs 1.68 kg, 5x300 cm - 1.83 kg, 5x450 cm - 2.44 kg, 5x450 cm - 2.75 kg. The mass of wider samples is as follows: 7.5x275 cm - 2.01 kg, 7.5x300 cm - 2.19 kg, 7.5x400 cm - 2.92 kg, 7.5x450 cm - 3.29 kg. Finally, the weight of the widest profiles is as follows: 10x275 cm - 2.34 kg, 10x300 cm - 2.55 kg, 10x400 cm - 3.4 kg, 10x450 cm - 3.83 kg.
CW or PS
This category refers to rack-mountable, however, the role of this component is slightly different than that of UD or PN. CW or PS profiles are used to strengthen the frame, give it rigidity and stability. They are fixed on the guides. The step, the distance between them is determined individually, but the standard indicator is 40 cm.
The dimensions of the profiles are very different from others, since here the count goes to tenths of a millimeter. This is about the width. It can be 48.8 mm, 73.8 mm or 98.8 mm. The height is 5 cm. The standard thickness is 0.5-0.6 mm. Weight also varies depending on the length and width of the profiles: 48.8x2750 mm - 2.01 kg, 48.8x3000 mm - 2.19 kg, 48.8x4000 mm - 2.92 kg, 48.8x4500 mm - 3.29 kg ; 73.8x2750 mm - 2.34 kg, 73.8x3000 mm - 2.55 kg, 73.8x4000 mm - 3.40 kg, 73.8x4500 mm - 3.83 kg; 98.8x2750 mm - 2.67 kg, 98.8x3000 mm - 2.91 kg; 98.8x4000 mm - 3.88 kg, 98.8x4500 mm - 4.37 kg.
CD or PP
These profiles are carriers. This means that they bear the entire weight of the structure and cladding material. Such profiles are suitable not only for indoor installation, but also outside. Mostly these varieties are used for ceiling mounting. By the way, the PP marking stands for "ceiling profile", which most directly indicates the main purpose.
As for the dimensional characteristics, the profile height is the same as the previous one - 2.7 cm. Available in only one solution in width - 6 cm. Standard thickness - 0.5-0.6 mm. The weight depends on how long the profile is: 250 cm - 1.65 kg, 300 cm - 1.8 kg, 400 cm - 2.4 kg, 450 cm - 2.7 kg. Thus, it will be possible to choose the most suitable profiles both in length and in weight, and the frame structure will still remain relatively light and strong.
Arched
Arch profiles are a unique product. Initially, the craftsmen tried to design arched openings using ordinary straight profiles, but nothing came of it. Then one of them came up with the idea to make cuts and fold the profile into an arc. Initially, the arc was angular rather than smooth, but that's better than nothing.
Eminent manufacturers picked up the idea, and so there were samples for processing arched openings. Both elements are produced that are well bent by the workers themselves, as well as profiles with a fixed curvature. The second case provides for a concave and convex profile, so that in which case you can attach curly elements to it. So, convex and concave elements are produced in the same standard sizes: the length can be 260 cm, 310 cm or 400 cm, the radius of curvature is from 0.5 m to 5 m.
PU
These profiles are angular. They are designed to protect the outer corners of the plasterboard structure from impact or destruction. A distinctive feature is the abundant perforation. The task of the holes is not so that through them it is possible to secure the attachment of the profile with self-tapping screws to the drywall, as in other cases. Here, the holes help the plaster to better adhere to the metal element, sealing it securely between the rough surface and the plaster layer. Only when fully fitted will it provide adequate protection.
The dimensional characteristics here will be special, since the corner profiles differ from the wall and ceiling profiles. So, the dimensions of the blades are 25 mm, 31 mm or 35 mm, and the thickness is 0.4 mm or 0.5 mm, depending on the cross-section. The standard length is 300 cm.
PM
Beacon profiles of this variety are used in the direct carrying out of finishing work, in particular, plastering. They are needed so that the rule glides as smoothly as possible, smoothing the plaster layer. So, the profiles are glued to the gypsum plasterboard directly with plastering mortar after a complex hanging procedure has been carried out. This is done in order to ensure an even application of the material layer, while avoiding unreasonable labor and financial costs.
The dimensions of the beacon-type profiles are slightly different from others. They are similar to the corner ones. Here the cross-section can be 2.2x0.6 cm, 2.3x1.0 cm or 6.2x0.66 cm with a length of 3 m. Please note that if it is necessary to increase the length (although this usually does not occur), the profiles are spliced.
Corner protection
In addition to standard PU, there are also various types of drywall profiles, the purpose of which is to save the corner sides from unnecessary damage. Of interest is a profile, in many ways similar to PU, but here, instead of perforation, wire weaving is used. This ensures the best adhesion of the element to the plaster, while it has a much lower weight and cost. The fact is that it is best to buy standard PU aluminum, while the improved analog can be made of galvanized steel.
The dimensions of the modernized corner protection profiles are the same as those of the standard ones. Their length is 300 cm, and their cross section is 0.4x25 mm, 0.4x31 mm, 05x31 mm or 0.5x35 mm. The weight is about 100 g versus the weight of 290 g of the usual PU corner profile. The weight difference is obvious, and if you do not plan to apply a thick layer of plaster, this option is best.
Hat
This profile for drywall is very different from all the others, both in its task and in the type of fastening. It is used in cases when it is necessary to provide high-quality insulation of the partition. The hat profile can be attached independently without the use of anchors or guides. It is usually used for arranging ceilings, but you can also attach it to the wall. It is made of zinc coated with a polymer layer.
The abundance of varied options is amazing. The thickness of the profiles can vary from 0.5 to 1.5 mm. The profile section depends on which model is selected. So, for profiles of the KPSh type, the cross section can be 50/20 mm, 90/20 mm, 100/25 mm, 115/45 mm. For PSh profiles, the values are partially similar: 100 / 25mm or 115/45 mm. Models of type H have completely different indicators: H35 - 35x0.5 mm, 35x0.6 mm, 35x0.7 mm, 35x0.8 mm; Н60 - 60x0.5 mm, 60x0.6 mm, 60x0.7 mm, 60x0.8 mm, 60x0.9 mm, 60x1.0 mm; Н75 - 75x0.7 mm, 75x0.8 mm, 75x0.9 mm, 75x1.0 mm.
Z profiles
The so-called Z-profiles are used as additional stiffeners. Usually they are purchased for roofing structures, but they can also be used to strengthen plasterboard suspensions, which has recently become more common. The manufacturers claim that it can replace two C-profiles. This will help save
Sizes can vary and depend on the type of instance.
- Z100 has a height of 100 mm, the width of the blades for all Z profiles will be the same - 50 mm each, thickness varies from 1.2 mm to 3 mm. The weight per meter of such a profile will also differ depending on the thickness: at 1.2 mm - 2.04 kg, at 1.5 - 2.55 kg, at 2 mm - 3.4 kg, at 2.5 mm - 4 , 24 kg, at 3 mm - 5.1 kg.
- The height of the Z120 profile is 120 mm, the thickness can be from 1.2 mm to 3 mm. Weight - 2.23 kg for 1.2 mm, 2.79 kg for 1.5 mm, 3.72 for 2 mm, 4.65 kg for 2.5 mm, 5.58 kg for 3 mm.
- The height of the Z150 is 150 mm and the thickness is the same as the previous versions. Weight varies: 2.52 kg for 1.2 mm, 3.15 kg for 1.5 mm, 4.2 for 2 mm, 5.26 kg for 2.5 mm, 6.31 kg for 3 mm.
- The Z200 profile is 200 mm high. Weights vary considerably: at 1.2 mm - 3.01 kg, at 1.5 - 3.76 kg, at 2 mm - 5.01 kg, at 2.5 mm - 6.27 kg, at 3 mm - 7.52 kg.
Higher options are usually not applicable to drywall applications.
L-shaped profile
An L-shaped profile is often referred to as an L-shaped profile, so keep in mind that this means the same thing. They belong to the corner, however, they perform a different function than PU or coal protection. L-shaped options are part of the carrier system. They are manufactured from galvanized steel. Their thickness starts from 1 mm, as a result of which the strength of the parts is achieved. Such profiles would be heavy, but the strong perforation eliminates this disadvantage. It is the L-shaped element that is used as the finishing or starting element of the entire construct.
The length of the L-shaped profiles can be 200, 250, 300 or 600 cm. Samples with the following thickness are presented on the market: 1.0 mm, 1.2 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3 mm. Please note that it is possible to order this type of profiles. This applies only to the length of the parts, the thickness should be chosen one of the suggested. The width of the profiles varies from 30 to 60 mm.
Additional elements
To carry out installation work completely, only profiles are not enough. We need some more details, with the help of which all the components are fastened into a crate box. Be sure to pay attention to the choice of these components, because if you choose the wrong one, the frame may turn out to be fragile and creak.
Some of the auxiliary elements, this partly refers to the connecting ones, can be done independently.
Extension cords
Numerous details are on sale in order to slightly extend the profiles. After all, buying a whole element for the missing 10 cm is not the most rational decision. It is not at all necessary to buy a special extension cord. To do this, you can use unnecessary trimming of the existing profile tape. For splicing, a guide profile is suitable, which will give the joint additional rigidity.
All that is needed is to insert a guide profile of the correct size inside and shape it with the pliers. Then it remains only to fasten the entire structure with self-tapping screws. You need to act carefully, constantly checking the evenness of the resulting profile.
Connecting elements
They are used if it is only necessary to connect two profiles without changing their length. These profiles can either lie in the same plane or form a multi-tiered frame. Different solutions are provided for each of these cases. Some of them can be made from the remnants of a profile part, others must be bought, third ones can be dispensed with altogether, but they still greatly simplify the work. However, it is necessary to understand all types in order to know which ones belong to which category.
There are 4 types of connectors. Three of them are used to connect profiles lying in the same plane, and only one is used for multilevel parts.
Longitudinal bracket
Above, we have already talked about the lengthening of the profiles with the help of an additional part of the profile. For such needs, there is a special device - a connecting longitudinal bar. With its help, you can simultaneously connect two profiles to each other and slightly lengthen them. Therefore, this part belongs to connecting, not extension cords.
The longitudinal bracket is a spring that abuts against the end parts of the profiles. It is made by hot-dip galvanizing. Thus, the manufacturers tried to give the parts more rigidity. For its final fixing, self-tapping screws or bolts are used. Sometimes the connecting bracket is not made of smooth metal, but of pimpled metal. It is believed that this will allow it to better adhere to the profile, especially if it is also uneven. In fact, this innovation only complicates the work.
Two-level bracket
These details are often referred to as "butterflies". These elements are among those that allow you to fix profiles of different levels. So, with the help of two-level brackets, overlapping parts are connected to each other, while their full fit and a rigid joint are guaranteed.
Two-level brackets refer to fixtures that are designed to facilitate the work of builders. Their fastening does not require the use of self-tapping screws: the design itself provides for special protrusions with which it is attached to the profiles. However, old-style elements still require special fixing means.
"Butterflies" are sold in a straightened form, but during installation they will need to be bent with the letter P and secured.
Corner
Corner connectors allow you to combine parts in the shape of the letter T. It is worth noting that such a connection is possible only in cases where the parts are on the same level, and not in different ones.
You can make such parts yourself. The homemade item was named "boots" because of its characteristic L-shaped shape. For this, ceiling rails are used, which are ideally suited for this due to their rigidity. So, parts of the profile of the required length are cut off, after which they are connected at right angles using self-tapping screws. Pay attention to the strength of the resulting joint. The joint must be as rigid and strong as possible to ensure the stability of the structure.
"Crab"
With the help of "crabs", the elements are connected crosswise only within the same level. In fact, the "crab" serves the same as the two-level brackets. "Crabs" provide rigidity of the connection, its strong fixation.
You can also do without "crabs" by replacing them with a homemade analogue. For this, two sections of the bearing profile are taken and screwed to the already fixed profile from the side of the channel. It turns out that the pieces of the profile seem to lie on their side. In the future, the profile, which should cross the existing one, is fixed inside such self-made grooves using self-tapping screws.
The resulting design is in no way inferior in functionality to specially purchased elements, so builders often resort to this method of fixing.
Plinth strip
This element can be attributed to fasteners. So, the plinth strip marks the border of the plasterboard structure being erected from below, from above, from the side, and the edges are more aesthetic. The end parts of the plank are perforated, which is needed in order to make it easier to plaster or otherwise process them before attaching the topcoat to the front side.
Plinth trims are made of aluminum or plastic. PVC elements are more comfortable. Cutting such planks is easy. So, you can cut off the right amount with scissors, while the edge will still remain even, it will not crack. There are two-piece PVC base / plinth elements that allow you to better form the joint between the plasterboard partition and the floor, since they have a sealing part.
How to choose the right one?
When choosing a profile, it is important to focus not only on its labeling, but also on the price and manufacturer, as well as on the material from which it is made. Before buying, you need to calculate the number of profiles. Ideally, you need to have a finished project on hand.
Pay attention to whether the parts are intended for walls or ceilings. Without taking this factor into account, it is impossible to choose a truly suitable option. Even if it is of excellent quality, it is not a fact that it will withstand loads for which it is not intended.
Check out manufacturer reviews. It so happens that domestic profiles turn out to be of better quality than foreign ones, while there is a good chance to save money without overpaying for the brand.
Fasteners
Installation is carried out by means of many parts, including both profiles intended only for gypsum board and universal ones. Before you go shopping, you need to calculate the number of fasteners. This requires a ready-made plan. The lathing can be complex or simple, and the required amount also strongly depends on this.
Fasteners are designed not only to fasten profiles together, but also to attach the entire structure to a wall or ceiling. Therefore, they must be strong to support such a great weight. When constructing a drywall module, you will need the entire list of parts listed.
Screws, dowels, screws
Not all of these elements are suitable for connecting profiles. There are three factors that affect the selection of fasteners: the material, its thickness, and the location of the position to be fastened.
Profiles can only be fastened together with self-tapping screws, belonging to the categories of drilling or piercing, respectively, marked LB or LN. These options allow you to work on metal, but you will have to make an effort to drown the hat and achieve evenness. By the way, these screws are called "bugs".
To attach the profiles to a wall or ceiling, you need reinforced nylon mushroom dowels. Self-tapping screws are already included.
Hangers
Regardless of the type, with the help of hangers, you can attach the profile frame to the wall or ceiling. The hangers are made of thin and flexible galvanized steel, ensuring that the weight of the part is only 50-53 g. Despite the seeming flimsy, the hangers can successfully withstand the weight of the structure. When working with them, you need to be careful. They do not withstand mechanical stress, and with awkward movement, the gimbal can easily be bent.
Direct suspensions are more often used, but there are also anchor ones. If the former can be called universal, since they are suitable for both walls and ceilings, the latter are used only for ceiling mounting.
Anchor
Ceiling anchor suspensions with clips are lightweight - only 50 g, nevertheless, they are able to withstand an impressive mass, while not deforming and not falling off the ceiling.
Anchor suspensions have other advantages as well.
- Low price. It is 8-10 rubles apiece.
- Versatility. Ceiling hangers, although they are intended only for ceilings, can be mounted in corners, and at joints with walls, and in open areas of the ceiling.
- High quality steel. The strength characteristics of galvanized steel and its flexibility are beyond praise, since the fasteners are responsible for the reliability of the entire structure.
- Simple installation and use. Installation of anchoring pieces is easy due to their intuitive design.
- Light weight.
Drywall has long taken a strong place in the building materials market. Usually such material is attached to the crate.
The main structure is a frame made of vertical and horizontal profiles. Their assortment is classified by type, size, purpose and other characteristics.
Peculiarities
A modern profile for gypsum board provides tremendous opportunities in creating a variety of geometric shapes and shapes. It helps to avoid monotony in the interior. With its help, you can make an original suspended ceiling and any module, sheathe walls, assemble an internal partition, a partition and many other structures.
The unification of profile structures facilitates the work of professional craftsmen and home craftsmen.
The metal frame for plasterboard sheathing is much stronger than a similar structure made of wooden beams.
The profile is made on special machines, which makes it possible to achieve accuracy in dimensions and ideality of lines. In addition, metal is more durable than wood.
The peculiarity of calculating and choosing the dimensions of the profile is that they must be produced based on several factors.
One of them is the thickness of the gypsum plasterboard, which affects the overall load of the structure. This is especially important when choosing rack-mount profiles.
If a single-layer lining of the profile with plasterboard is supposed (load up to 8.5 kg per m²), it will be enough to use products measuring 50x50 or 50x40 mm. If the expected load is higher, a 65x50 or 75x50 mm profile should be used.
Views
In order not to make mistakes with the choice and confusion in a varied assortment of profiles for drywall, certain knowledge of their types may be required. They differ among themselves in dimensional characteristics, metal thickness, cross-sectional shape and raw materials from which they are made.
The main profiles for creating frame bases for ceilings and walls are of several types.
Guide
Such a profile is marked with PN (UD), which means "guide profile". Its cross-section is U-shaped, the side walls are smooth, holes for fastening are made in the back.
A guide or starter profile is used to create the main support (for uprights and lintels).
It is attached along the perimeter of the structure, subsequently the rest of the components are installed in it.
Rack
This option is marked PS (CD), means "rack profile". It is inserted into the guides, drywall sheets are attached to it... In this regard, the main burden falls on him. That's why the stiffness of the rack profile should be maximum.
Its cross-section has the shape of the letter P, but the design of the PS is equipped with additional shelves and stiffeners.
Ceiling
It is marked PP and PPN, which means “ceiling guide profile” and “ceiling bearing profile”. The sections PP and PPN are made in the form of the letter P in shape, but have smaller dimensions than that of the wall profile. The ceiling profile has shelves of lower height and stiffening ribs. The small height of the shelves is due to the need to reduce the "selection" of the height of the room with a plasterboard ceiling.
Reinforced for ceiling
It has UA marking, metal thickness 2 mm. It is used to create reinforced frame bases for suspended ceilings.
In addition, it is used as part of a structure for fastening window and door frames.
Arched
It is a kind of rack and guide profiles. It is designated by the abbreviation PA (CD). Used to assemble structures with radial bends.
The main distinguishing features for this species are pronounced perforation and the presence of side cuts, which provide an opportunity for profile bending. In some cases, the arched profile can be made independently by cutting the shelves of the ceiling plinth into sectors, and then bending in a given radius and direction.
Partition
- Guide... It has the UW mark. In principle, it is similar to the UD profile, but has slightly different characteristics: greater height (40mm) and width (usually 50, 65, 75 and 100 mm).
- Carrier or rack-mount... It is marked CW and has a shelf height of 50mm.
Additional profiles and accessories
When creating structures in which drywall and metal profiles are used, additional elements cannot be dispensed with. Their assortment is varied and includes several varieties.
Angular
It has a rectangular cross-section with a slightly protruding center part.
It is used to form corners of plasterboard structures.
Corner profiles also have several subspecies:
- Both shelves are perforated with large holes which allow the corner to become part of the plaster layer and thus be securely held.
- With mesh, which is glued along the edges of the profile in the form of strips. As a result, enhanced adhesion is achieved with subsequent finishing measures.
- On paper base... In this case, 2 metallized strips are glued to high-density paper. Such elements are used where a small load is expected (in window openings, the edges of shelves and niches).
Beacon (PM)
It is used as a beacon or support guide in order to obtain a smoother surface when plastering. The most widespread are beacon profiles with a length of 3 m and sections: 22x6, 23x10, 62x6.6 mm.
Perforated hangers
Metallic
Metal anchor hangers for ceiling profiles are used for the design and installation of suspended ceilings.
With the help of anchor hangers, it is easy to adjust the height, as well as to set the plane of the ceiling.
Connectors
A single-level and two-level connector for a ceiling profile is called a "crab". It is a plate with clamps for fastening cross profiles.
Used for suspended ceilings.
Extension
The profile extension is a small bracket 110x58 mm in size for splicing two pieces of the same size.
Materials (edit)
Drywall profiles are made of steel and aluminum. Steel profiles (simple or galvanized) are more widespread in finishing work.
Aluminum, despite the excellent performance properties, are much more expensive.
Dimensions (edit)
For the convenience of installation work and to make it easier to choose the material for work, the standard system of dimensions for drywall profiles provides several options for the main parameters. Guide profiles are available in various lengths and widths, but the main dimensions of the PN profile are as follows (the first parameter is the width, and the second is the height):
- 28 x 27(for wall and ceiling structures);
- 50x40mm, 65x40mm(some manufacturers have a CD profile width of 60 mm);
- 75x40mm, 100x40mm(for partitions).
As for the length, it is usually presented in four versions: 2.5 (2.6), 3, 3.5 and 4 meters. If a longer profile is required, for example, 5 m, it is made to order or connected from separate sections. The wall thickness depends on the manufacturer, it can be from 0.4 to 0.6 mm.
Rack profiles are usually available in four main sizes:
- 50x50mm;
- 65x50mm;
- 75x50 mm;
- 100x50mm.
Their standard length assumes sizes of 2.5 (2.6), 3, 3.5 and 4 m. Many manufacturers of rolled metal products accept orders for products of greater length.
Ceiling profiles have a size of 60x27 mm (ceiling guide) and 27x28 mm (ceiling support).
How to cut?
Before you start working with a metal profile, you need to know how you can cut it. It is necessary to prepare the appropriate tools. Usually, a jigsaw, grinder, hacksaw or metal scissors are used for this.
Jigsaw
A file for metal is installed in the tool. Cutting starts from one of the profile edges. First, the rear part is sawn, and then the side edges. When using this method, there is a high quality cut and no burrs.
Grinder
An angle grinder (angle grinder) will be an excellent assistant in profile cutting. With this tool, the cut will turn out faster than using a jigsaw.
However, working with an angle grinder requires certain skills. With a lack of experience, there is a high probability of leaving the marking line and getting an oblique cut.
Hacksaw
When work with power tools is not available, an ordinary hacksaw for metal comes to the rescue. In this case, you need to start the cut from the edge, then you need to go to the back and side parts of the profile..
The inconvenience of this method is that the profile can be deformed during the sawing process under mechanical action. In addition, the time and power costs are much higher than when working with a jigsaw or a grinder.
Metal scissors
This is a fairly simple and most common way of cutting a metal profile. The cut with scissors is made strictly along the marking line. Using a quality tool is one of the guarantees of getting a beautiful cut.
The most difficult thing in this method is the likelihood of going off the marking line when passing the edge.
For a flawless result, you may need a little workout or combining the cutting of the ribs with a hacksaw, followed by finishing with scissors.
Despite the fact that the dimensions of the profile elements are sufficiently standardized, it is desirable to form a set of profiles to create a metal frame from the assortment of one manufacturer. Otherwise, you run the risk of encountering some inconsistencies, such as: different parameters of the length, width and depth of the profile, the thickness of the metal, as well as its quality. This significantly increases the risk of installing a metal structure with reduced strength. This may affect the finished result of the work.
Choosing the thickness of the sheet, you need to think about the fact that the thicker the metal, the stronger the structure, but also its cost increases... Therefore, experts recommend optimizing all parameters and stop at the choice of metal 0.5 mm for ceilings and 0.6 mm for walls... The thicker the metal, the more reliable the structure will be. The economy version using thin steel may not withstand significant loads.
