Entrance doors must reliably protect the house from unwanted visitors. It can not always provide finished products offered by specialized shops. A high-quality door, with the presence of the necessary conditions and tools, can be made independently. Detailed information about this is set out.

Steel door design

The entrance doors are made of wood and metal. But the benefits of steel doors are obvious:

• the design made of sheet metal, profile pipes and corners is characterized by high strength;
• steel doors are not afraid of temperature drops;
• metal is not prone to deformation under conditions of high or low humidity level;
• long service life;
• aesthetic attractiveness: The entrance doors made of steel can be decorated forged details and decorative lattices.

Important: steel doors can be made exactly in terms of opening. It will save from the need to expand the opening using the cutting diamond instrument.

The materials for working on the steel door will be needed as follows:

• sheet steel: The sheet dimensions are selected depending on the opening (about 1850 × 900 mm), thickness - 2 or 3 mm;
• for the manufacture of the door leaf: steel corners 40 × 40 mm or profile pipe - 10 m;
• for door box: Steel corners 50 × 50 mm - 12 m;
• door loops - 2 pcs;
• anchor bolts - 6 pcs;
• mortise locks;
• eyes;
• insulation (foam plastic, polystyrene foam, mineral wool);
• mDF panel with a thickness of 8-12 mm (for the inner and external facing of the canvas) - 2 pcs;
• foam assembly;
• perimeter seal self-adhesive;
• platband;
• stengips - for the design of the side walls of the opening;
• decorative paint.

Assembly and installation of steel doors - Tools for work

To process metal, assembling doors and their installation, you must have at your disposal the following tools:

• bulgarian with cutting and sharpened metal discs;
• welding machine and electrodes with a diameter of 3 mm;
• drill with a set of drills;
• hammer;
• screwdrivers;
• perforator;
• roulette;
• marker;
• corolnic;
• construction level;
• clamps.

IMPORTANT: Tips from steel door installation professionals agree that the correct connection of the parts of the door leaf and the box is possible only on a flat surface, which can be used by the workbench of the corresponding sizes.

Technology production of steel doors

The whole process can be divided into the following steps:

• frame manufacturing;
• manufacture of door leaf;
• installation of loops, locks and other accessories;
• warming, sheathing of the canvas.

Before proceeding with work, we make a project of steel doors for home. It is a detailed drawing of the design with the indication of all sizes, the places of installation of the fittings, the location of the technological holes.

Step-by-step instructions: how to make a steel door

During the manufacture of parts of the metal door and assembly, the following rules are followed.

Production of steel door frame

1. On the workbench put steel corners, sliced \u200b\u200bin size according to the parameters of the opening, leaving the gap of 10-15 mm on each side.
2. In places of welding (in the corners), spins are made under 45 degrees, the corners are connected at right angles (controlled by the coal).
3. The parts connected are fixed by clamps, after checking and adjusting sizes: the lengths of diagonals should not be different than 2 mm.
4. Clamps are removed only after cooling the metal heated by welding.
5. Plates with holes for fastening the design in the opening are welded to the finished frame.

Basic parts of steel door

Making a steel door cloth

1. The canvas should be freely in the frame, for which, during the assembly around the perimeter, remote plates are inserted with a thickness of 4-5 mm during the assembly.
2. The metal sheet of the canvas should close this clearance and enter the frame.
3. In order to ensure the strength of the web, on the inside weld the ribs of stiffness.
4. Welding seams and burrs after cutting metal are cleaned with a grinder with an abrasive sharpening circle.

Installation of fittings and steel door trim

Door canvas insulated expanded polystyrene

1. The loops weld to one of the sides of the canvas (the choice depends on the direction of the opening) and at the same time - to the frame. The distance from the upper and lower edge is 150-200 mm. It is important to comply with the alignment so that during opening and closing there is no deformation and jams.
2. The door eye is installed at the level convenient for all living in the house.
3. The insulation of the door leaf is performed using foam or extruded polystyrene foam. The material is cut for styling between the ribs of stiffener. The gaps are filled with mounting foam. On the edge of the canvas (throughout the perimeter), the rubber seal on a sticky basis is placed.
4. The door leaf from the insulation side is closed by the MDF panel made on request. This panel can also be used for external finish.
5. Other options for finishing steel doors: Coloring for metal, PVC film sticking, with wooden clapboard, leatherette (see photo).

Tripping doors lining

Tip: In order for the door with the cavity loop, the attacker could not remove, the design should provide for the riglels. Anti-removal is also effective in the form of short (40-50 mm) pins, which are installed in the end of the web side of the loop.

Box in the steel door locks

For reliability, locks for steel doors are installed at a distance of 250-300 mm from each other. The procedure for the following.

1. The mounted door is installed vertically, after which there are places for cutting locks.
2. With the help of a drill, drill holes for bolts of locks. If the slots are needed - they use the Bulgarian.
3. Drill holes for fastening screws. In order to hide the screws of the screws, perform the crown of a large diameter drill.
4. Set temporarily locks in place, place and drill holes for the parts of the handles and lining.
5. Install locks and handles, securely fasten them with screws to the canvas.
6. With chalk or chiffel rubbing the piglets of locks, after which the doors are closed and planned places for holes in the frame.
7. Arrow holes and fasten decorative planks.

Installation of mortise locks

Important: If steel door opening systems provide for the installation of vertical locking bolts, to install the mechanism should be envisaged between the rigidity ribs.

Installation of steel doors

1. Preparation of the opening: the old doors and box are dismantled, the fittings are cut.
2. Frame is installed. It should occupy a strictly vertical position, which is controlled by the level. For temporary fixation, wooden wedges use.
3. Fastening the frame with anchors. For them, through the holes in the plates with the perforator, the holes are drilled.
4. Placed on the loop door canvas. The loops are pre-lubricated with lithol.
5. Loop adjustment is performed: the door leaf should be well in the frame, without distortion and rubbing.
6. Rama and canvas are painted before facing the finishing material. This will protect the metal from corrosion and increase the life of the product.
7. The gaps are filled with mounting foam, the walls of the opening are plastered, decorative coating is applied.
8. With the external and inside, platbands are installed.
