Metal entrance doors have already become an integral attribute of any apartment and premises with buildings, where safety for the owners is paramount. Here we will talk about the production of metal doors, equipment and technology for their manufacture. They are in very good demand and have recently been installed by the developers themselves in new apartments, because if they do not install them, then their new owners will do it anyway.
The advantage of this metal entrance door business is that the process itself is quite simple and does not require any additional knowledge from you. Therefore, any entrepreneur can do it.
Equipment for the production of
For the manufacture of powder-coated metal entrance doors, the following equipment is required:
- Metal cutting machine. Plasma or laser is used, because they cut evenly and as quickly as possible. Price from 100,000 rubles.
- Press brake. Price from 700 thousand rubles.
- Welding equipment for spot and finishing welding. These can be ordinary machines or welding machines. Price from 100 thousand per unit.
- Equipment for powder painting: a complex for surface preparation before painting, a spray booth (from 60 thousand rubles), a polymerization oven (from 150 thousand rubles), a painting gun, a compressor.
This is with regard to machine tools, but there are also ready-made complexes (lines) for the production of metal doors, which combine all these machines. They look something like this:
They come in different configurations.
The price for the line presented above is 6 million rubles. It has everything for the production of metal doors, except for the painting function, namely: a plasma cutting machine, a press brake, a machine for coordinate welding of door leaves, 2 stations for welding with pliers with conductors, 2 stations for final welding in carbon dioxide. This line is designed for 8 people with a capacity of 10 doors per hour.
Manufacturing technology
The whole technology for manufacturing entrance metal doors is very simple:
- The metal is cut, and all the necessary holes for the locks and eyes are made, because if you do this after painting, it will lead to cracking of the paint around these elements;
- Then it is bent;
- Assembly and initial - spot welding are performed;
- If everything is in order, then a final finishing welding is performed;
- After all this, the door is prepared for painting and placed in a spray booth. There it is painted through a spray gun and then placed in a polymerization oven.
You can watch the whole process in the video:
PS: do not forget about an additional service that you can provide during self-retail sale - installation of metal doors. It will bring you additional "kopecks".
Today variety metal doors and manufacturers, gives the buyer the opportunity to choose the necessary door for any operating conditions. The metal door market has a fairly wide range of products, the price policy of which ranges from the cheapest to the most expensive, which directly depends on the quality of the product. So, for example, doors of an elite class will have a correspondingly significantly inflated cost. A question such as the selection of a door to an apartment or a country house is resolved fairly quickly and does not take much time. Everyone knows that the production of metal doors in Yoshkar-Ola has long become a trendsetter of new technologies and quality of metal structures. It should be noted that all designs have all the necessary certificates and guarantees. It should be noted that not all metal doors are guarantees of your protection. Unscrupulous manufacturers, including China, make doors from low-quality or thin steel, thereby turning the front door into a kind of "wooden" one.In our production, only high-quality steel with a thickness of 1.4 mm is used., As well as all stages of production iron doors in Yoshkar-Ola are carried out under strict quality control.
The main stages of the production of metal doors:
- cutting metal sheets with a thickness of 1.4 mm;
- marking of the main technological holes in the steel sheet;
- preparation of the constituent elements of the future door leaf and frame;
- door frame manufacturing;
- welding of door block components;
- painting a metal structure with special paint in several stages;
- manufacturing of the inner panel of a metal door;
- insulation and soundproofing of the structure;
- door assembly, with the installation of locks and fittings;
- quality control, packing.
Our production is focused on the manufacture of metal doors in standard sizes. In this case, metal doors with a height of 2000 mm and a width of 800 to 1000 mm are considered standard. It is, of course, possible to install narrower and lower doors, but this approach is not thoughtful - after all, you will have to not only pass through the front door, but also bring all the furniture and household appliances into the house, and this will be extremely difficult with a more modest door size ...
Today, we offer you a large line of entrance doors in a wide price range. It is possible to manufacture doors according to individual projects, as well as non-standard sizes and colors.
The assortment of the modern construction market is rich: in specialized stores you can. Metal, wood, plastic, combined - all entrance doors have special specifics in terms of manufacturing. The desire to independently make a metal door block arises for a number of reasons. For example, you want to get a design with specific requirements and additional materials, you need a high quality product at a minimum cost.
Tools and materials
Making a metal door with your own hands actually refers to the budget option: creating a product yourself will cost much cheaper than buying a finished structure. Of course, in order to make a truly functional and stylish door, you need to own a tool and have some experience in welding.
In addition, you will need competent blueprints, quality materials, and professional tools. Let's list the main components that are used in the process of creating a metal door composition:

The list of the above materials and tools required to create a metal door is approximate: the final solution depends on the type and functional value of the future structure. For example, when making a vestibule or entrance door, it is best to purchase a thick metal sheet. You can also use two sheets of metal: in this case, the space between them must be filled with insulation.
A metal workbench table will be very useful
Another interesting material for making a door, although not an entrance one, is.
Step-by-step manufacturing instructions
The creation of a metal door consists of four main stages: the manufacture of the frame, the production of the metal sheet, the installation of fittings and the sheathing of the product. A typical door structure is two meters high and 90 cm wide.
Consider the features of working on creating a metal door:
- Frame ... It is necessary to start making the frame after all measurements have been taken. The dimensions of the door frame should be optimal: the metal frame should harmoniously fit into the doorway, therefore, a gap of 2 cm should be left on each side.
- Canvas ... It is also necessary to leave gaps between the frame and the metal sheet, while the sheets should protrude slightly from the edges of the frame. It is necessary to carry out welding work in small areas. The seams are made no more than 4 cm in length, while the distance between adjacent seams should not exceed 20 cm.
- Fittings ... For the production of loops, steel rods with a diameter of 2 cm are used. The loops are welded to the canvas and the metal frame at the same time. Professionals recommend carrying out mandatory anti-corrosion treatment of the product: with its help, the door will serve for more than a dozen years.
- Cladding ... You can use any material you like: vinyl leather, PVC film, artificial leather, leatherette and others.
The main steps in making a metal door with your own hands:
- Measure the opening and leave about 2 cm from the walls to the box in order to eliminate all cracks with foam. In addition, such a gap will correct the door installation in the event of a skewed opening.
- Cut a metal corner according to the selected dimensions (approximate dimensions - 50x25 mm) and place it on the welding table. Measure the length of the diagonals of the rectangle: they must be equal. Welding can only be started if all dimensions are the same. This is how the door frame is made.
- Measure the finished box along the inside, taking into account the 1 cm gap on each side of the structure around the perimeter. Cut a corner with dimensions of 40 * 25 cm for the canvas. In the lock profile, use a grinder to make a small slot at the optimum level for installing the lock.
- At the same time, wooden slats of optimal dimensions are hammered into the metal profile. This is done to simplify the facing work.
- Also, for the convenience of welding, it is recommended to immediately weld the loop profile to the metal box and hinges. It is necessary to ensure a perfect match of the hinges and the door frame: for this, the distance between them is carefully checked. If this condition is met, it will be easy to hang the door.
- It is necessary to check: whether the profiles of the door leaf and the frame are parallel, after which the remaining profiles of the door leaf are inserted and welded into the latter.
- Then a sheet of metal is welded. First, the canvas is measured: on each side, the door should be closed by 10 mm, while on both sides of the lock - 15 mm. The sheet is cut according to the dimensions taken into account, laid on the product from the profiles.
- First, the loop is welded from the back of the sheet in the inner cavity, then the sheet is welded around the perimeter.
- A false strip is welded on the inside of the metal sheet. For better strengthening of the door structure, special stiffening ribs can be welded.
- Clean the welds and paint the product. It is recommended to paint the door even if you will later cover it. Additional coating will prevent corrosion.
- Install two locks. To do this, a hole is drilled in the corner for the entry of the crossbar, then a slot is formed for fastening the lock in the metal sheet. You can also cut a hole for the door lock.
- Carry out the door trim. It can be sheathed with wood planks or panels, glued with a PVC film that repeats the wood texture, or, for example, use leatherette. Many people simply paint the canvas and then weld interesting forged decorative elements to it. You can also use curly metal sheets or soft elements.

For owners of apartments that have something of value, one day the question arises of strengthening their home. The most obvious and simple solution in such a situation is to install a reliable door. There are a lot of varieties of metal entrance doors on sale and it is quite difficult to immediately navigate in all this variety. What type of steel door to choose, how they differ - these questions will be answered in this article.
Characteristics of entrance metal doors
All metal doors, regardless of their class, are much stronger and safer than wooden ones. This truth is not disputed by anyone. But among themselves they differ in characteristics quite strongly.
- security - this means how long a metal door can withstand attempts to break it;
- comfort - in addition to protective properties, steel doors are also chosen for such qualities as excellent sound insulation and fire protection;
- reliability is the quality of any metal door is determined by its service life, ease of use and protection against breakdowns;
- aesthetics is another property, according to which a choice is made, because it will be in his house or apartment, which means it should be in harmony with the interior.
All of the above qualities are important when choosing a metal door. But very often one of them prevails over the rest, and some is practically absent.
Properties of metal doors
All metal doors are made of high-strength and stainless materials. Mainly cold rolled alloy steel is used in their production.
The internal structure of the doors is very similar to each other in all classes. It is a door leaf, consisting of a metal frame, which is made of iron corners, steel bent profile, the same shaped pipes. Then, flat steel sheets are welded to the finished frame, and the cavity between them is filled with various cushioning materials. It can be foam rubber, polypropylene foam plates, mineral wool or natural wood. All-metal doors are rarely made, usually when they are used to protect a safe room and premises such as a bank vault, cash desk, etc. These doors are called armored. The thickness of the metal used in steel doors varies.

Hinges in steel doors are made using special technologies. They must meet the requirement to hold a lot of weight. The door frame is one of the largest parts apart from the door leaf. The closing device in metal doors is located in a protective pocket, this is done in order to increase protection and increase reliability against some burglary methods. Stiffeners are considered a mandatory part of a steel door, which support the shape of the door and prevent it from deforming from impacts.
The basis of any metal door is a special profile and a sheet made of steel are structural elements responsible for strength and reliability. The seal used inside the door leaf is responsible for comfort and sound insulation. This component of the door also affects the retention of heat inside the apartment.
Basic installation steps
Tools required when installing a metal door:
- measuring devices (tape measure, level);
- hammer;
- electric drill;
- a set of keys and a screwdriver.
The installation steps can be broken down into the following steps:
- opening preparation, which consists in removing interfering pieces of mortar and other debris;
- installation of a door in an opening that was prepared in advance;
- fixing the frame to the level. To do this, you need wedges that are installed between the steel frame and the wall;
- then, using an electric perforator drill, holes are made in the wall for anchor bolts;
- inserting anchor bolts and fixing them with nuts;
- filling with foam or a special solution of the gaps between the frame and the wall;
- removal of the protective coating from the door leaf.
Classes of metal doors
According to the price criterion, doors are divided into economy class - cheap, premium class - expensive and high quality, and elite - the most expensive and exclusive.
Economy class metal doors
Economy class includes metal doors, the main task of which is to protect a house or apartment in combination with a low price. They are distinguished by a simplified design and lower quality. Reducing the cost of such a metal door allows you to save on external decoration. Most often, powder coating, inexpensive laminate and other cheap materials are used, but despite this, the door can look pretty decent.
Due to the observance of the technology of their production, this group of doors has good sound insulation, heat preservation and blocks the ingress of unpleasant odors. Economy-class Chinese metal doors are available to a wide range of consumers.
Premium metal doors
The premium class combines steel doors characterized by the following characteristics: sophisticated design, high quality of structural elements and a corresponding high price. When finishing these doors, more expensive materials are used - this is a high-quality lining, complex powder coating, expensive laminate. Premium steel doors have less wear and tear, provide more security and have a sophisticated design.
Elite metal doors
Elite doors are very expensive as they are made from expensive materials. In their production, only high-quality locks and fittings from the best manufacturers are used. Excellent designs tailored to the customer's interior are the hallmarks of the highest cost door group. In such doors, natural materials, expensive finishes, and additional armor plates are used to the maximum. Elite doors are usually available only for wealthy people.
Separately on this list are doors made by non-professionals in the so-called "handicraft" way. They are sometimes offered by craftsmen. They are made in garages, using a welding machine and a circular saw. They are made of very thick and cheap metal, but do not contain seals and interlayers, which would increase sound insulation.
What to be guided by when choosing a metal door
Choosing a steel door for himself, a person focuses on such indicators and factors as price, burglary resistance, durability, maintenance cost, visual appeal, ease of use, heat resistance, sound and heat insulation. But the importance of these factors varies depending on where the door will be installed and how much money is available to purchase it.
Steel doors that are suitable for most of the characteristics of a person can be too expensive. The opposite situation will lead to the acquisition of an unreliable metal door. All manufacturers declare that their metal doors are reliable and burglary-resistant. But in fact, the difference between the time required for a professional to open a metal door in an inexpensive and expensive category is about 6 minutes. The simplest metal doors in this respect open in just a couple of minutes, and those considered impregnable - in 8. And the difference in price is from ten to twenty thousand rubles. So how do you make the right choice?
The best way to protect yourself from a thief is to install an apartment alarm in addition to the door.
It is from the response time of the security agency employees that one should make a start when choosing a door according to the criterion of resistance to burglary - it should be enough for the timely appearance of the guard.
If the main criterion is the appearance of the door, then it is best to focus on the interior and furnishings of your apartment and the harmony of the door with the facade of the building. In this case, the use of a combined cladding and a detailed study of the design will be appropriate. These services are currently provided by many companies that manufacture steel doors on a professional basis.
The official division of locks for metal doors into classes
A door lock is another important structural detail of a steel door, which is characteristic of absolutely all types of doors. From the installed lock, the classification of metal doors depends on the degree of security provided. According to GOST 5089-97, which is called "Locks and latches for doors", the state establishes four classes of locks.
Let's consider them in more detail:
- the first class includes locking devices that have very low burglary resistance characteristics. It is believed that they do not present any obstacles to theft due to their low strength qualities;
- locking mechanisms are suitable for the second class, in which the protective characteristics are at the usual level, and the strength properties are below average. GOST establishes the time it takes to open such a lock without keys. It is about five minutes;
- the third type of locks has the highest security qualities and the average strength of the materials included in them. The definite time for breaking them is ten minutes;
- the last variety is the fourth grade. They have high protective properties, are made of extra strong materials and resist opening for about half an hour.
When determining the time of opening, it meant the working time of a high-class burglar with a special tool. The average person rarely manages to pick even a second or first class lock.
Classification of doors by degree of security, by type of coating and by dimensions
Safety classification
By analogy with the classes of locks, metal doors also differ. According to the properties of reliability and resistance to burglary, they can be divided into three categories:
- ordinary - they are equipped with locks of 3-4 classes and blocking devices and obstacles to removal. These include economy-class metal entrance doors;
- reinforced steel doors - also contain class 3-4 locks inside, equipped with blockers that prevent them from being removed, the hinges of such doors are reinforced, and the perimeter is closed with multi-head locks. Most often, premium metal entrance doors have such protection;
- protective metal doors - have the properties of previous types, but additionally prevent opening by squeezing, squeezing and other similar moments.
Classification by type of coverage
If we consider the classification of doors by type of coating, then they can be divided into the following groups.
Metal doors with a transfer coating. It provides a more attractive appearance while being striking and aesthetic. Often this type of coating imitates others. Perfect for use in places protected from moisture and sun.
The Teflon coating is black, which gives the door a strict and discreet look. This coating material is virtually scratch-resistant and does not fade when exposed to UV light. Teflon is an excellent coating for doors that are installed in country houses and in contact with the street.
Coating with auto enamel. A special technology that helps to achieve a balance between quality and visual appeal. These doors can be installed in apartments and houses.
Hammer-transfer coating - on the one hand, such a door is faced with a hammer method, which gives it resistance to scratches, chips, etc. From the side of the home, the coating is transfer, which allows you to choose it in accordance with the interior.
Sizes and methods of opening metal doors
Door dimensions are also taken into account when classifying them. A distinction is made between standard sizes and custom-made doors.
By the number of locks, metal doors are divided into one- and two-lock. Elite doors are usually made with two or more locks.
By the way of opening, the doors are subdivided into right-sided and left-sided. There are doors that open 90 degrees, others can open 180 degrees.
What to look for when choosing metal doors
- On average, the size of the door frame is 2000x800 mm, which does not always correspond to the size of the doorway in a particular case. Therefore, first the height and width of the opening are measured, and only then the door is bought or (in case of a non-standard size) is ordered;
- thermal insulation in the door leaf should be made of foam or mineral wool, and rubber seals are installed around the perimeter. You can often stumble upon a trick of the manufacturer when he writes that the door is insulated with batting on both sides. This means that under the cladding on both sides there is a layer of batting only 5 mm thick, which is clearly not enough for heat and sound insulation;
- When buying cheap Chinese metal doors of economy class, the base price includes only the black color of the finishing coating. It must be borne in mind that you will have to pay extra for any other color;
- the quality of the door is also indicated by the locks installed on it. The most budgetary models are equipped with two types of locks - upper lever and lower brown Mosrentgen. At the same time, more expensive and presentable models are always placed on the advertising photo. Both of these locks are very popular due to their low cost, but they do not provide the necessary burglary protection;
- the next thing you need to pay attention to is the thickness of the door frame, on which the heat and sound insulation of an apartment or house also depends. It can be standard from one profile pipe 5x2.5 cm or reinforced with a thickness of 7.5 cm.
The cost of metal doors
As mentioned above, the price difference between the classes of entrance doors is very significant. But with the right choice, you can buy a solid and reliable door even for little money.
Economy class metal door price
But if there is a desire to buy not just a reliable, but also an exclusive and luxurious thing, then you should stop at elite doors.
For production and storage facilities, technical metal doors of economy class are used.
