The role of the front door cannot be overestimated. This is the main barrier to intruders entering the house and at the same time a key detail in the design of the room. The market is saturated similar products, among which buyers prefer metal structures. Unfortunately, the purchase does not always justify the money spent: quality budget options in many cases it is low, and there is no money for a good product.
The thought of making it yourself arises. If you have a welding machine and the skills to use it, then there is nothing complicated. You need to figure out how an iron door works, draw a drawing, buy material, components and get down to business. Thoughtful, careful work with careful adherence to the sequence of operations will allow you to create a design that surpasses many industrial designs.
Homemade metal door - advantages and features
Those who fear that it is very difficult to assemble an entrance steel structure at home are exaggerating. Modern equipment and materials allow manufacturing to be completed in a short time. There are several reasons why you should take this step:
- the choice of material for the product is carried out personally - there is no need to worry about its quality;
- if the doorway non-standard sizes, individual order too expensive;
- possible various options finishing, creation of exclusive design;
- you will have to spend some money, but the total cost is significantly lower than a purchased door.
A private house, especially outside the city, where the owners rarely visit, requires reliable protection from the entry of strangers. A good steel door at the entrance copes with this function. Many products are only menacing in appearance, but opening them is not difficult. The tin is so thin that it lends itself to a can opener. In a structure made with one’s own hands, no one will interfere with the installation of sheets 2–3 mm thick.
Sometimes an additional interior metal door is installed. She is not out of place in a communal apartment, where she sometimes has to live together with dubious characters. In a private house the second entrance structure serves as another barrier for attackers. In addition, an insulated door means additional savings on energy resources. She herself does not let the cold in, and if there is another one at the entrance to the room from the corridor, a warm one is created air gap between them.
The bathhouse is also quite often equipped with a steel entrance door. Outside the city, as a rule, it is a separate building and needs protection from the entry of strangers. The location itself requires such a design to have a heat-insulating layer, otherwise the metal will quickly cool the room. One more nuance: surface finishing is required so that in the cold the hands of a person running out of the bathhouse do not get caught on the iron.
home component steel door - canvas. It is made from a single sheet of metal 2–3 mm thick. They are welded to the door frame from the corners from the entrance side, and on the inside it is made wood paneling. Stiffening ribs are installed in the frame. Filling is placed in the space for thermal insulation: polystyrene foam, mineral wool. Another element is a box, which is made from a rectangular pipe 50x25 mm or larger.
It is important to choose the right loops. Hidden ones serve as additional protection against burglars and do not damage general view. To prevent the structure from warping due to weight, install required amount, depending on its mass. Up to 70 kg, two are enough; if more, 3–4. To make doors easier to move, buy products with bearings or balls.
A mandatory attribute is locks, of which it is customary to install two. One is a safe, has increased resistance to physical impact and burglary tools. The second is a cylinder, it is believed that the key cannot be forged. Another element of protection is the end iron pins, which prevent the door from being removed even when the hinges are cut off.
Getting started - making a box
First, the doorway is measured. If it's too big for standard door 900×2000 mm, the excess is covered with bricks and blocks. When the deviations are not very significant, they leave it, because the design is made by hand, and the parameters special significance Dont Have. There are 1.5–2 cm gaps between the box and the wall on all sides, which are filled with foam.
A drawing is made that serves as a guide for assembly and installation. The dimensions of the frame, door frame, leaf, as well as the location of stiffeners, hinges, and locks are applied to it. Knowing the dimensions of the door, they calculate how many and what length of blanks are required. Industrial products are made from bent profile, which is produced at special machine. Use at home rectangular pipes 50×25 mm.
To ensure that work does not cause inconvenience, it is necessary welding table. Any material is used for manufacturing, even durable ones. wooden beam. The main thing is that the surface is absolutely flat and located in the same plane. It doesn't have to be continuous. They make the strapping - for a standard door 90x200 cm, 1.2 mx1.75 m is enough. 2 more crossbars are inserted along the width, checking the horizontality with a stretched rope.
The door frame, or ludka in carpenter's slang, must ensure that the door is tightly closed. To do this, protruding overlays (rebates) are installed on the inner perimeter, or a special metal profile is made on a bending machine: thickness 1.5 mm. Hinges are installed on one vertical beam, and locks on the other.
Cut long and short pieces, lay them out on a flat surface with the narrow side up. Check the angle, which should be 90°, and the distance between the diagonals. After making sure that they are correct, they grab the parts. It is also necessary to install linings inside the frame, where it will rest door leaf. They are made from the same profile, only they are installed flat, or a corner is used.
Correctly calculate the depth to which the seams are welded. It depends on the thickness of the door leaf. Its plane is closed position should completely slam the box. Add 3–5 mm per rubber compressor.
The contours of the box are already visible, all that remains is to check the correctness of the shape once again and thoroughly scald it. Don't forget that metal heats up. Short sutures are applied in a dotted manner from the center to the sides. During the second pass, the missed areas are boiled. Install the mounting plates on the side. All seams are cleaned with a grinder.
Some people may not like the fact that the pipes have open ends. But they will be hidden in the wall opening when the slope is finished, and the insides will become inaccessible to moisture. You can plug or cut the workpieces at an angle of 45° and weld it that way. It's much more complicated.
How to make a door leaf - the easy way
It is important to create the frame correctly: to ensure rectangular shape, location in one plane. When the production of the box is completed, it is not removed anywhere: it will be used to assemble the door frame. This is very convenient and much simpler: you don’t need to constantly take measurements or draw – everything is done locally. Proposed step-by-step instruction installation is based on this option.
First they cut vertical racks, taking into account that a gap of 3 mm is required at the bottom and top. The first is placed on the folds of the box from the hinge side. To ensure the required distance, a 3 mm flux-coated electrode is installed between the ends, sides and shell. Press with clamps and grab in several places. Then it will be trimmed with a grinder.
A similar operation is performed with reverse side. A rectangular hole is first cut in the profile to install the lock. Only a gap of 5 mm is required, so the “five” electrode is used as a template. Then measure the distance between the side posts, cut short cross members and weld them in accessible places.
Next, stiffeners are inserted. There are quite a lot of options for location and quantity. The simplest one is one pipe exactly in the middle along the frame. To achieve greater rigidity, they are supplemented with short corners located in each half.
Next, the clamps are cut off and the frame is scalded in places where there was no access before. Do it gradually, without heating the metal too much, so that it does not lead. Then the seams are cleaned with a grinder, achieving a smooth surface on the outside.
The sheet is marked so that it is 20 mm longer in length and 25 mm longer in width. Place it on a flat surface and place the door frame on it. Place it so that the canvas protrudes by 10 mm at the top, bottom and on the side of the hinges, and by 15 mm where the locks are.
Weld, starting from the middle, moving towards the edges. Make short seams no more than 4 cm on each side alternately, skip 2 cm, which are then welded. Periodically allow the metal to cool. They grab it in several places to the stiffening ribs - it turned out front side canvases. The inner lining is installed after filling the space thermal insulation material. It does not extend beyond the edges of the frame and is fixed flush.
Complete instructions for making a door are presented in the video.
Installation of external and hidden hinges
Canopies for an iron door are somewhat different from those intended for structures made of other materials; they are not interchangeable. The most common type is with an ordinary ball bearing installed between the hinge parts. It creates an easy move and allows you to hang any weight of canvas. The simple version has a cylindrical shape.
Drip canopies differ only in appearance, but are more convenient for installation. Conventional ones are installed using small plates that provide clearance between the hinges and the door. Steel rods instead, after welding and grinding with a grinder, look more aesthetically pleasing. Drop-shaped ones do not need gaskets; the shape itself provides the necessary clearance.
External hinges with bearings are easy to install; the main requirement is to maintain alignment, otherwise the door will not open well. To install external canopies with your own hands, follow the following sequence:
- place the door frame horizontally and insert the leaf into it;
- carefully check the gaps between them;
- the cavity of the canopies is well filled with lubricant so as not to accidentally catch the halves during welding;
- put the loop in place, pointing the pin upward;
- they slip in gaskets or turn the drop, ensuring a gap, and weld.
Hidden canopies are fully protected from cutting: the angle grinder will not help intruders. The hinges are securely hidden in the internal cavities when the door is closed. In addition, they have a number of other advantages:
- aesthetic appearance - do not stand out on the canvas;
- ease of use - you can adjust the position of the shutters;
- durable – hidden from the weather, not required additional care or lubricant.
Internal hinges
Installing hidden canopies is much more difficult. First prepare special rectangular holes V door frame and the frame of the canvas. They weld it inside, which is already inconvenient. You should buy models with small boxes in which hinges are installed. They are pushed into the prepared openings and scalded.
You can install hidden canopies yourself. The basis is ordinary cylindrical hinges with a bearing, additional elements cut from profile pipe. The picture above shows this design when the door is slammed shut. Using the diagram, it is not difficult to make internal hinges for an iron door with your own hands.
Last steps – finishing up to full functionality
All metal is cleaned of possible rust, coated with primer and painted. This also applies outside door leaf, even if it follows decorative finishing other materials. There are many possibilities: MDF, lining, natural wood.
You need to install a lock: watch the video on how to do this.
The location of the lock is marked at the end of the frame with a rectangle. The dimensions are a little larger so that the part fits easily, but not too much, especially in width. This way the wide slot will not be blocked by the mounting plate. Marks are placed on the canvas in places where mounting holes need to be made. Use a drill of a larger diameter, since it is difficult to achieve complete coincidence on both sides.
The lock and handles are inserted, and decorative plates are secured. The ends of the crossbars are coated with paint and the door is covered. There will be marks on the door frame. Grooves are cut along them. To create additional protection against burglary, a piece of corner is welded to the frame. For reliability, a thick steel plate under the lock would not hurt.
Before installation internal lining carry out insulation. Foam plastic is usually used, less often - mineral wool. Cut into pieces and place in the space of the door leaf without gaps. To seal, all joints between the metal and the heat insulator are blown in polyurethane foam. It is also used to fill the stiffeners through pre-drilled holes.
To seal the junction of the canvas with the box, a rubber seal is installed on the fold. Before purchasing it, measure the perimeter and find out the required length. They also differ in thickness. To decide which one is needed, place a piece of plasticine and close the door.
Finishing remains inside. The choice of material is at your discretion. For a garage, utility rooms, chipboard or galvanized sheet metal is suitable, for a bathhouse - natural wood. If the door is in an apartment, a more aesthetic cladding is required: MDF panels, laminate, PVC or wooden lining.
Make metal door It’s quite possible to do it yourself if you approach this process competently The front door is one of the most important elements apartments. It protects the house from unauthorized entry by intruders, so this design should be as strong and reliable as possible. Metal entrance products are in particular demand, but their cost is quite high. If you want to get a door for a minimum cost Money, or you need a design of non-standard sizes, then you can make it yourself.
Why you may need to weld doors yourself
Gone are the days when you could leave your house open and not worry about all your valuables going missing. Even when you are in an apartment, you cannot be sure that robbers will not break into an unlocked door. Therefore everything more people replace thin ones wooden panels, armored metal structures.
The construction markets offer a huge range of steel entrance doors. All of them have an attractive appearance and are positioned by sellers as reliable, impenetrable structures. However, often after the purchase it turns out that the iron “armored” door you purchased is opened with an ordinary hairpin or kicked out. This drawback is typical for Chinese models.
When you make a metal door yourself, you can be confident in its quality, practicality and safety.
High-quality imported and domestic products, the reservation of which truly meets all standards, have a high cost.
If you want to become the owner of a durable metal door, then make it yourself. Making such a structure yourself is not as difficult as it might seem, and you will spend several times less than you would pay for similar design in the shop.
Production durable doors at home, requires the presence of a fairly large list of tools and materials. Most of them can be purchased at a hardware store, but some will have to be ordered from the factory.
Tools and materials that will be needed to make the door:
- Two-millimeter steel sheet;
- Several meters of profile pipe;
- Two door hinges;
- Door fittings (handle, lock and peephole);
- Anchor bolts and mounting foam;
- Drill and grinder;
- Welding machine;
- Insulation material;
- Plywood or boards;
- Finishing materials finished design.
We have provided you with a universal list of tools. Depending on the purpose of the product and its design, some materials may be added, for example, forged elements.
How to make a drawing of a metal door with your own hands
Before proceeding directly to the manufacture of the door, it is necessary to take measurements of the doorway. It is also important to carefully inspect the walls adjacent to the area where the door will be installed. They must be made of concrete or brick, since the metal structure is too heavy for a plasterboard base.
Before you start making a metal door, you first need to prepare its detailed drawing
After all the measurements have been taken, it is necessary to make drawings of the future door. The scheme must match actual dimensions to scale. In your drawing, show the installation location of the lock, stiffeners and door handle.
In order for a homemade door to look no worse than a purchased one, you need to carefully consider every nuance before making it. You can also add designs decorative elements, for example, decorate with glass or forged patterns.
The drawing will help you see all the shortcomings of the circuit and understand in time whether it is necessary to add stiffeners or whether it is better to leave everything as is. Also, based on a well-drawn plan, it will be easier to weld the door correctly.
How to weld a door from a profile pipe: making a door frame
Before making a door, it is necessary to properly prepare the doorway. How flat this part of the apartment is will determine how tightly the steel structure will fit against the walls.
The doorway must be carefully puttied, plastered and adjusted in size to the door frame. You can make sure that the doorway is processed correctly using a level.
You can use profile pipes to make a door frame
When the doorway is prepared and its dimensions match the dimensions door design in the drawing, you can proceed to assembling the frame. This is what they do first, since it will be easier to make a canvas based on the size of this element.
The material for creating the door frame can be thick profile pipes. With their help, it is possible to weld the most durable structure.
Making a door frame:
- First of all, you need to measure the parameters of the already prepared doorway and cut the profiles according to these dimensions. Please note that the finished door frame should be approximately 1.5 cm smaller than the doorway. In this case, the installation of the door structure will go as smoothly as possible.
- Next, you need to lightly weld the frame elements to each other. This is necessary so that in case of an error, you can easily redo your work.
- Now you need to re-measure the iron frame. The distance is measured from corner to corner diagonally, as well as vertically and horizontally.
- If the frame is perfectly flat, then the final welding of the elements is carried out. Welding areas are polished with a special machine.
- On last stage it is necessary to drill holes for the anchor bolts and weld the hinges. The welding areas of the loop and profile are cleaned with a grinding machine.
The design of the door frame cannot be called complex. If you have minimal welding skills, then you can handle this stage of creating a door without much difficulty. However, if this is your first time holding a welding machine in your hands, we advise you to first practice on pieces of metal corner.
Making an iron door leaf with your own hands
After the assembly of the door frame is completed, you can proceed directly to the manufacture of the door frame, and then to welding on it sheet metal. For these purposes, you can use a metal corner and a two-millimeter steel sheet.
Before you start making an iron door, you need to properly prepare the tools for the job.
How to make a door leaf with your own hands:
- The metal corner is cut into pieces the right size. To do this, you need to take measurements from the inside of the box. The door leaf should be 5 mm smaller than the frame on all sides.
- The frame elements are welded. Diagonals are checked.
- A stiffening rib is welded vertically in the center of the frame. It is also necessary to weld the horizontal profiles; one half will need 2 metal ribs.
- Now you can mark the steel sheet. It should be 1 cm larger than the door frame on the lock side, top and bottom, and at the point of attachment to the hinges, an overlap of 0.5 cm should be left. The cut steel sheets are welded to the frame.
- Welding areas must be cleaned using a grinding machine.
- Drill a hole and holes for the lock and install it on the door. Don't forget to make a hole for the door peephole.
- Weld the door hinges to the frame and door leaf.
- Insulation is placed inside the door structure between the stiffening ribs.
- We decorate the inside of the door with a sheet of plywood, which can then be covered with veneer or wallpaper.
- The metal side of the door needs to be primed and then painted or covered with leatherette.
If you wish, you can make a glass insert in the door leaf or decorate it with elements of artistic forging.
The resulting homemade door has all the characteristics of its purchased counterparts. However, it will cost you much less than a finished design and may even be of better quality than many factory-made options.
How to properly weld an iron door with your own hands (video)
Making a metal door with your own hands is not as difficult as it might seem at first glance. Even if this is your first time holding a welding machine in your hands, with a little practice you can create a pretty decent product.
Sections of the article:
On the entrance door market steel structures rightfully occupy one of the leading positions. The manufacturing technology and positive characteristics of the material make it possible to prevent unauthorized entry into the premises and withstand all illegal attempts to open it by selecting door keys, destruction or deformation of the canvas. Range finished products in specialized stores is quite extensive, but making an iron door with your own hands is not only possible, but also accessible to virtually everyone. It is only important to have the desire and experience of working with a welding machine, as well as to strictly adhere to the sequence when working with materials and tools.
The main reasons for making steel doors yourself include:
- Non-standard dimensions of the final structure;
- The embodiment of an exclusive designer's idea;
- Use of special materials;
- Opportunity to obtain a high quality product;
- Economic component.
A high-quality iron door has high protective properties, provides sufficient heat and sound insulation, and has a long service life.
Iron structure design
The process of manufacturing an iron door should begin with the creation of a drawing, which indicates the actual dimensions of the product. The resulting diagram will serve as the basis for the assembly and subsequent installation of the door.
You need to start by measuring the width and height of the doorway. The obtained measurements are transferred to paper, a diagram is drawn future design with the specified width and height of the door leaf.
The standard size of the metal structure is 900 mm x 2000 mm. If the dimensions are larger, then an additional block is installed on top, covered with sheet iron, glass, grating, or a blind or hinged block is welded to the side. All elements are specified in the project.
The dimensions of the door frame should be 2 cm smaller size doorway. The resulting gap will subsequently greatly simplify the installation process of the box and allow it to be adjusted if necessary.
The number of hinges is calculated taking into account the weight of the structure; as a rule, 2 - 4 canopies are used. To evenly distribute the load, the hinges are welded at the same distance from each other. In this case, the first and last ones are welded at a distance of 15 cm from the outer edge of the door.
The next step is to strengthen the door frame with additional stiffeners. The main stiffening element is located in the middle of the door leaf, and additional stiffening ribs can be placed from the corners of the product or from the hinges, which will evenly distribute the load over the entire area of the door. The main thing is that the stiffeners do not interfere with the insertion of the lock or the installation of the handle and eye. Stiffening ribs must provide strength finished product, their number is also chosen at your own discretion.
Materials and tools
TO necessary tools for assembling an iron door with your own hands include:
- Electric drill;
- Screwdriver;
- Bulgarian equipped cutting disc for metal;
- Clamps;
- Set of files, grinding machine;
- Set of measuring tools.
- Steel sheet (2 - 3 mm thickness with dimensions 100 x 200 cm);
- Metal corners for the frame (3.2 x 3.2 cm 6 r.m.);
- Profile pipe for the box and stiffeners (5x 2.5 cm 9 lm);
- Door awnings;
- Reinforcing plates for attaching the door frame to the wall (40 x 4 cm, thickness 2 - 3 mm, 4 pcs.);
- Door fittings (locks, handles);
- Anti-corrosion protective compounds, dye;
- Polyurethane foam, anchor bolts.
To materials for manufacturing standard design relate:
The range of door hardware and locks is quite diverse, the choice depends solely on personal preferences. But the most popular mechanisms are locks with bolts on three sides. Such products are much more difficult to install, but also protective functions theirs is significantly higher.
If the iron door is intended for utility rooms, you can use a more simplified and low-cost financially option: the function of a rigidity amplifier will be performed by a reinforcing rod.
Assembly steps
The process of assembling a metal structure consists of the following steps.
Collecting boxes
Frame parts are cut from a profile pipe and laid in the form of a rectangle on the welding table. All dimensions are checked again, including diagonally. A control measurement will allow you to set the angles exactly at 90 degrees. A correctly adjusted structure is tacked by welding.
After completing the welding work, it is necessary to check the perpendicularity of the sides and measure the distance between opposite pairs of corners. Compare source data.
If everything turned out correctly, you can proceed to the final welding work. Upon completion, the seams must be sanded. Then the reinforcing plates are welded to the door frame.
Assembling the door leaf
To assemble the leaf, it is necessary to take measurements of the inside of the door frame. On each side we retreat 7 cm - these are the dimensions of the future structure.
From metal corners The blanks are cut to the required length and undergo pre-treatment to remove burrs. The prepared corners must be laid inside the structure to form a rectangle. After that, control and measuring actions are carried out.
If any nuances appear, they must be eliminated and all parts adjusted to size. The connecting points are welded tightly.
The next step is to cut the material for the stiffeners, they are tightly welded to the door frame. It is important to take into account all the places indicated in the project for installing the lock and related fittings.
Exterior view of the frame with welded stiffeners. Fabrication of the sheet begins with laying the steel sheet on a welding table or trestle. The finished frame is placed on top of the sheet and a contour is drawn according to the dimensions specified in the project, while an indent of 10 cm must be made from the outer edges of the frame.
According to the outlined contour, it is cut out steel sheet, sections of cuts must be polished. Prepared canvas using welding machine mounted to the frame.
An important point: in order to prevent distortion, welding cannot be done with a continuous seam.
The optimal welding seam is 30 mm sections with an intermediate distance of 15 - 20 mm. To avoid subsequent hidden defects, during operation, the product must periodically cool down, otherwise it may need to be repaired in the near future.
Having finished with the outer side of the door, the canvas must be turned over and the door frame placed on top.
To make it easier to fit the box to the frame, you can use pads, the thickness of which is from 2 to 5 mm; they are laid along the entire perimeter of the structure. A sealing tape will later be installed into the resulting space to improve the soundproofing qualities of the door.
When the door leaf is completely ready, special cuts are made for installation internal lock and a peephole, a hole is drilled under door handle. Edges of holes in mandatory subject to grinding.
An important point: the size of the hole for the lock must simultaneously allow installation of the lock without play and provide free access to it in case of repair work.
For a padlock it is necessary to provide special pads.
Installation of door hinges
The upper canopies, equipped with grooves, are attached to the door frame, and their lower parts with pins are welded to the door frame. Docking seams must be sanded.
collected metal structure must first be cleaned of foreign particles (dust, shavings) and treated with an anti-corrosion compound. The final touch is either tinting or decorative finishing of the door.
To understand in more detail and clearly how to assemble iron doors do it yourself, it is recommended to first study the video, which clearly shows the entire process from A to Z.
Door installation work
A box is placed in the doorway and the structure is adjusted relative to the opening; all actions are carried out using a plumb line or a building level.
Installation work on installing the door frame takes place only with its geometrically correct location. Anchor bolts are used to secure steel hinges to the wall. After which you can hang the door leaf on the awnings.
Checking the correct installation: the iron door should open and close freely, and the hinges should work smoothly and without unnecessary effort.
Installing a lock and door handle
After installing the lock, end sides The crossbars must be rubbed with chalk and made marks on the door frame. In the marked places, holes are cut out - grooves for the crossbars.
If there is a need for additional protection lock, you should weld a corner of the required length to the door leaf in those areas where the bolts come out. Another way is to strengthen the door leaf in the place where the lock is installed. To do this, a 6 mm thick steel plate is welded on the inside. At this stage, it is recommended to adjust the operation of the locking mechanism and ensure that the door fits tightly to the frame.
Having studied detailed instructions manufacturing, you can understand how to properly make a metal structure. It’s quite possible to assemble an iron door with your own hands at home, the main thing is to arm yourself necessary material and a tool.
Time forces you to save. At the same time, increased demands are placed on home security. Metal doors are an invariable attribute of every city apartment. An alternative to them in terms of reliability is only entrance doors made of solid wood, but they are incredibly expensive and themselves provoke an attacker to break in. Nice door made of metal and installation are also expensive. An alternative is a do-it-yourself metal door.
Of course, a homemade door cannot be a full-fledged analogue of a factory one: in artisanal conditions It is impossible to comply with the manufacturing technology. But opening a metal door is quite difficult, and it will produce the necessary psychological effect.

14. Clear welds, paint the canvas with protective enamel or powder paint.
16. The inside of the door can be covered with MDF panels.
Metal Entrance door ready with your own hands. All that's left is the installation.
Installation methods
Attention: often if you install a factory door yourself, you lose the warranty on it.
First way installation of the canvas in the opening - using mounting plates(if you made the iron entrance door yourself, you can weld them in advance).
1. Three plates (eyes) are installed on each rack. When installing the box, the plates must be adjacent to the wall from the inside (so that they cannot be cut off).
2. Place the box in the opening and measure it vertically. There should be a gap of about two centimeters between the box and the opening.
3. Holes for fastening are drilled through the holes in the plates and anchor bolts are inserted.
4. Foam the installation gaps. Once the foam has hardened, the excess is cut off.
5. Hang the canvas on the hinges.
6. They install the best locks for metal doors.
7. Close the gaps with platbands. If the walls of the opening are wide, they are covered with MDF panels.
Second way: if the walls of the opening are wide and the box is recessed inside.
1. Place the box in the opening and align it vertically. The gaps between the box and the walls are from half a centimeter to a centimeter.
2. Through the mounting holes in the box, drill holes for fastening in the wall of the opening (depth - 10-15 centimeters).
3. Insert anchors and tighten.
Third way: concreting the box.
In this case, a hollow box is used, the inside of which is filled with concrete. Measure the vertical position of the box, fix the box to the wall with anchors and leave until the solution has completely set.
2. Before hanging the canvas, the hinges need to be lubricated. When adjusting the hinges, loosen the fasteners on them.

First of all, you need to decide appearance future door, make it yourself or find a sketch or photo of it on the Internet. I printed the sketch to scale, based on the actual dimensions of the doorway. If the opening width in the sketch is, for example, 20 mm, this means that its real width is 2 m.
To make the door, it's best to start with a frame that I welded from angle metal.
We mark the corner and cut it with a grinder at 45 degrees.
We apply the carpenter's corner to the corner of the frame, maintaining an angle of 90 degrees.
Having welded the corners, we grind them with a grinder and a grinding disc.
From the same corner and a metal strip (20×2) I made blanks for the door frame. The template will help you calculate the exact distance to weld the strip. To do this, a template is applied to the inside of the corner (50×50) along with a strip (20×2), then the strip is welded to the corner.
In the future, the strip will serve as a plywood retainer. Then the excess material is cut off along the entire length of the corner.
On one of the strips I made a hole for the lock so as not to have to do it later when the whole frame is ready.
We make the key hole at a distance of 900 mm from the edge of the corner.
We make metal blanks for the door frame according to the dimensions of the internal frame. A frame for the doors is created from the already made corner. It is made in height and width internal size door frame.
In order to avoid rubbing of the frame and door frame, you need to put metal plates between them, which I made from the same 20x2 mm strip.
Between the frames we insert our blanks - metal plates 2mm thick.
Now we weld the door frame.
As a result, we got a door frame and a door frame.
We weld a sheet of metal to the resulting door frame. Edge distance metal sheet to the frame - 15mm
For the future window, use a grinder to cut out an opening in the center of the door.
We also make stiffening ribs, as shown in the photo, and weld them to the door so that it does not bend and retains its shape.
The initial number of stiffeners was not enough, so additional ones need to be made.
But this was not enough, so add diagonal ribs for strength.
There should be as many stiffening ribs as will allow the door not to bend.
This is what your resulting design should look like.
Using a drill and a drill bit with a diameter of 4.2 mm, we make a hole, then use a tap to make a 5 mm thread.
We fasten the lock to the door frame with bolts with a diameter of 5 mm.
Using a marker, you can make markings for the future hole for the core of the lock.
First, we drill a hole using a drill and a drill bit with a diameter of 12 mm, then we finish this hole with a round file.
Now let's cut out a rectangle from plywood to the size of the future door for the inside of the door.
Now let's work on the loops. To choose their location correctly, you need to retreat 150 mm from the top and bottom edges of the door.
In this case, the hinges should be positioned so that the lubrication holes face the front part doors.
We weld around the perimeter of the door frame square pipe(20x20) to close the gap between the frames.
Now let's take small strips (40x4) of metal that will serve us to fasten the doors, and weld them perpendicular to the surface of the door. With their help, the door will be secured in the doorway.
We make two holes in the door frame for the lock “tongues”. We make markings for the “reeds” directly from the lock attached to the door.
To protect the lock, we weld a corner.
Now let's start painting the door. First we will cover it with primer paint.
After the primer layer has dried, cover the door with black paint.
We use foam chips as insulation for the door. It needs to be mixed with PVA.
Then carefully fill the entire surface of the door with the insulation mixture.
We fasten the pre-painted plywood with rivets to the door frame.
Now we paint the door on both sides with hammer paint.
To avoid drips and distribute the paint evenly, it is advisable to lay the door horizontally.
We have an empty hole for the window. We install in it decorative grille made in the technique cold forging metal
In addition, we need to install double-glazed windows to keep the door warm.
The door is ready, now it needs to be installed in the doorway. To do this, you need a level to keep the door vertical. I welded a metal strip perpendicular to the frame; a hole with a diameter of 12 mm is made in it for fixing anchor bolts(D12mm and length 100mm).
Now the door not only gives you a feeling of pride and satisfaction for the work done, but is also ready for constant use.
