The choice of a steel door
In the Russian market represented a great number of steel doors both domestic and imported. They differ, first of all, the price - import, usually two to three times more expensive than domestic. But, according to specialists, is not worth saving. The thing is that come from outside the doors are made with modern equipment and the latest technology. Our door is in the majority going to artisanal.
Obviously, the quality, alas, is not «in our favor». However, most import models «tied» to the model size (for each company - they own). Order for production «custom» door may take only a few firms, but the door will cost considerably more expensive, and it will have to wait two months to a year and a half. But domestic door can be customized and relatively inexpensive in the short term.
Common device
The device of domestic and imported steel doors little different. At the core of the door - a rectangular frame with an inner edge of the rigidity of the welded steel structure. On the frame are welded steel plates (with one or two sides). Door hang up on the hinge in the steel box, reinforces the doorway. Outside the door knocked leatherette or decorative panels (the most expensive trim - wood). Inside the door can be hollow and may contain noise insulation and thermal insulation material. The difference in «anatomy» imported and domestic steel doors can be only in the thickness of steel sheets. We import doors thicker than sheets of 1.5 mm, while in Russia using a steel sheet of thickness 2 - 3 mm. As a result, our doors are produced massive, heavier. But this does not mean that they are reliable (excess weight \\ “is \\” hinges on the strength).
It is desirable that the assembly was composed of platband and the arches. These details greatly increases the reliability of construction, excluding the possibility of breaking the door or scrap fomkoy.
On the import of steel doors and arches platband is necessary, but the Russian could not have. An important element in the steel doors - hinges. They, too, can be both foreign and domestic production. It is necessary to ask the seller what weight they are free to stand up to (the most reliable are the hinges on the supporting bearing). The number of loops is calculated individually for each door. Particular attention is paid to castles. Many experts believe that the most secure locks - suvaldnye, they are often - crab (when «tab»-bolt go in 2-4 tracks from different sides door canvases). The more complex the castle, so it is more expensive. Better to install a door lock, two, one - crab, the other - simple. Moreover, it is desirable that a castle was suvaldny another - Cyl. Larvae of the lock cylinder must be protected bronenakladkoy that it could not dislodge. Well, when the bolt locks are hidden in the metal tube that can rotate - then bolt is virtually impossible perepilit.
Frames
Experts advise to buy the doors, manned by imported locks. It is believed that they are more robust: less likely to go down, the number of combinations of keys is from 500000 to 4 billion should be taken seriously, and the choice of accessories. At a steel door must be fitted eye and the inner gate. Very nice eyes with a radius of 200-degree view. Imported door without the eye does not produce, and at home - eyehole assembled to order. You can order a peephole installed in such a distance from the floor, so that it could look a child. Valves better buy a spiral, rather than sliding, the latter with zahlopyvanii door may accidentally close.
Price
Now about the price. It consists of multiple components: the door is taken into account the size, type and number of locking devices, external finish, the availability of accessories. In addition - the price for delivery, installation, measurement, counseling, the dismantling of the old doors. Yet, perhaps, to pay for the increase in the aperture, the aperture tab bricks, installing platband, delivery door in the floor (if the house without a lift), etc.
It is important
In conclusion, I would like to note that it is important to choose not only the door, but the company involved in the sale and installation of steel doors. Outcome 50% 25 depends on the quality of the door itself, the remaining 50% of 25 - to the quality of its installation and maintenance.
When choosing the company should pay attention to such things as well-known companies, the experience of work in the market not less than 5 years, the availability of a company network or demonstration points, solid design of the booth, friendly staff, at all stages of communication with customers.
