The feeling of security creates input metal doors, and they must meet the following requirements:
Diagram of the device of a metal door with insulation.
- reliability and aesthetics;
- convenience of use;
- fire safety;
- high-quality sound insulation;
- Long service life.
You can install a Russian or import door.
Installation of the domestic metal door
In Russia, their manufacturers are engaged in professionals with great experience in the work in this industry. On modern technological equipment, a single-mounted profile box is manufactured with a rigidity rebier that prevents the door deformation during operation. Included with the canvas necessarily go to the focus and platbands. The platband is necessary to close the gaps after installing the door box, and the sequence closes the gap between the door clove and the box.
Scheme of a metal door box.
It is possible to produce inlets of steel doors not only standard sizes, but also to order, taking into account all the wishes of the customer: the size, metal thickness, materials for heat and thermal insulation, fittings, external and interior decoration. Performance of work in the execution of an order for the manufacture of a non-standard door costs the customer much more expensive. Their size is defined, as a rule, two values:
- The size of the canvas;
- Sizes of the opening.
Standard blocks of metal doors for residential and non-residential premises are determined by GOST 31173 - 2003. The document clearly describes all the most important parameters that must be observed in the manufacture of steel doors produced in the territory of the Russian Federation.
Steel sheets in the manufacture must be welded with each other with durable seams, without cracks and influx.
Dimensions of the doorway
The door frame made of flexible profile must be a thickness of at least 1.5 mm. The rolled steel used by the lesser thickness can lead to the deformation of the door canvase. Then the repair or replacement of the canvas will be required. If a rectangular profile is used in the manufacture, then its dimensions must be 40x50 mm.

In modern panel housekeeping, the dimensions of the doorway are spelled out in the director general of the development and should be:
- width - 740-760 mm;
- Height - 1950-1980 mm.

In houses built from bricks, permissible are considered:
- Width - 880-929 mm;
- Height - 2050-2100 mm.
Typical series of houses built at the end of the last century, had door openings:
- Width - 830 - 960 mm;
- Height - 2040 - 2600 mm.
Construction rates and standards are always withstanding in modern home-building. Each company tries to surpass a competitor in providing even such small amenities as an increase in door sizes. You can, of course, buy and standard, providing high-quality installation by its good materials.
Non-standard outlook sizes need to be measured. Fully remove all overhead details of the old door and clean the opening from the garbage and the creaked plaster. It is necessary to check the verticality of the walls of the opening with a plumb and measure the distance between the walls, floor and the upper point of the opening.
Metal doors must have a strict geometric shape: height, width and diameter. Permissible deviation of 3 mm. The design must have high quality external coating. If the external or interior decoration does not match the sales contract specified in the contract, then the customer may require replace the product.
Metal doors insulation
Tools for pitching metal doors.
The canvas can be hollow, and maybe at the request of the customer, to be filled with insulating material that reduces heat loss and increasing sound insulation.
This uses:
- mineral wool;
- polyurethane foam;
- Polyfoam, etc.
Such a soft insulation, like mineral wool, should be isolated from the metal surface with a layer of waterproofing.
This layer is necessary for the insulation of the condensate formed during temperature drops. Minvata filled with condensate vapor can apply a significant metal surface damage, even if it has an anti-corrosion coating.

Hard insulation are inserted into the canvas tightly, without gaps.
You can use bulk insulation, but only if the rigleels are not installed inside. Otherwise, they will be blocked.
External warming of metal doors is not required.
The door frame insulate the mounting foam or through the drilled holes fall asleep the bulk insulation.
All materials used for heat insulation must meet sanitary safety requirements. In addition, a rubber seal is laid around the perimeter of the door box, and the door of the door is magnetic, which increases the density of the adjuncture. With the help of the installed eccentric, the density of the adjustment of the door canvas to the box is adjusted.
Finishing metal doors
Mounting Metal Door Mounting Scheme.
The outer and interior decoration of metal doors may be different. Russian manufacturers offer many finishing options, which is characterized by high quality:
- vinylister of Russian and imported production;
- Genuine Leather;
- laminated wood panels;
- powder thermal phase;
- MDF panels covered with PVC film or veneer or painted in any color, thickness of 8 or 16 mm, with any milling pattern (even on the client sketch);
- violent (with trimmed by valuable wood);
- Possible installation of double-glazed cars;
- It is possible to use forged elements, chasens, stained glass windows, automatic and manual wood threads, stones inlays, various types of artificial aging.
The decorative finish used in the manufacture must be made of high-quality materials and have a solid grip with the base. Facing parts made of wood should be completely covered with varnish or other protective material and have a small area of contact with the metal.
Door hinges and locks
When installing hinges on metal doors, anti-removable pins are installed. Welding or rolling them are fixed in the doorway frame or door box.
They are installed from 2 to 5 pieces. The more they are installed, the more holes need to drill. And this leads to a decrease in operational qualities.

To ensure greater safety, manufacturers recommend setting 2 different types of locks: suvalid and cylinders.
Suwald locks have a complex protection system not only from unauthorized opening of the door, but also from its drilling.
Cylinder locks are characterized by simplicity of operation, in extreme situations it is possible to replace the entire lock, but only its parts - cylinder. In it, the plates are located in a combination that makes it possible to open the door only intended for this lock key.
