The choice of a steel door

In the Russian market represented a huge amount of steel doors of both domestic and foreign production. They differ, first of all, the price - import, usually two to three times more expensive than domestic ones. But, as experts say, is not worth saving. The fact is that supplied from abroad doors are made using modern equipment and latest technology. But our doors to the vast majority of home-going. Obviously, the quality, alas, not in our favor. " However, most imported models are "tied" to the standard size (with each company - they own). Order to produce "custom" doors can take only a few firms, but this door will cost considerably more expensive, and it will have to wait two months to fifteen years. But the domestic door can be custom-made relatively inexpensively and in a short time. Common device unit of domestic and imported steel doors do not differ much from each other. The basis of such doors - a rectangular frame with an internal rib, welded steel profiles. On the frame is welded steel sheets (with one or both sides). Door hinge in a steel box, which reinforces the doorway. Outside the door leatherette stud or decorative panel (the most expensive finish - natural wood). Inside the door can be hollow and may contain soundproofing and heat insulation material. The difference in the "anatomy" of imported and domestic steel doors can only consist of thick steel sheets. We import the door sheets, no thicker than 1.5 mm, while in Russia use steel sheet thickness of 2 - 3 mm. As a result, our doors are obtained heavier, harder. But this does not mean that they are reliable (overweight "had" the strength of the loop). It is desirable that the kit includes frames and arches. These details greatly increase the reliability of a design, eliminating the possibility of breaking the door with a crowbar or a crowbar. On imported steel doors of the porch and the trim is optional, but the native can not have them. An important element of a steel door - hinges. They are, again, can be both foreign and domestic production. Need to ask the seller how much weight they are free to stand up (the most reliable are the loop on the support bearing). Number of loops is calculated individually for each specific door. Particular attention should be paid to castles. Many experts believe that the most reliable locks - lever, they are also most often - crab (when the "tongues"-bolts go into 2-4 directions on different sides of door leaf). The more complex lock, so it is more expensive. Better than one door lock to install two, one - crab, the other - simpler. It is desirable that one was a lever lock, the other - cylinder. Larvae of the cylinder lock to protect the armored plating so that it was impossible to dislodge. Well, when deadbolts locks hidden in a metal tube that can rotate - then bolts almost impossible to saw through. Experts advise buying locks the door, complete with imported locks. It is believed that they are more reliable: fewer fail, the number of combinations of keys ranges from 500,000 to 4 billion should be taken seriously, and the choice of accessories. On a steel door must be fitted eye and the inner gate. Very convenient eyes with a radius of 200 degrees view. Imported doors without eye does not produce, but on the native - peephole mounted on request. If you prefer, you can order a peephole installed at a distance from the floor, so that it could look a child. Valve is better to get a screw instead of sliding, the latter collapses at the door may accidentally close. Price Now about the price. It consists of multiple components: consider the size of doors, type and number of locking devices, external finish, the availability of accessories. Also - the price for delivery, installation, measurement, consulting, dismantling the old door. Still, might have to pay for the increase of the opening, the opening tab brick, installing casing, delivered doors on each floor (if the house is no lift), etc. Important In conclusion I would like to note that it is important to choose not only the door itself, but also firms involved in sale and installation of steel doors. The end result is 50% dependent on the quality of the door, on the other 50% - the quality of its installation and maintenance. When selecting the firm should pay attention to such things as the firm's reputation, years of experience in the market for at least 5 years, the availability of the firm network of stores or demonstration points, solid stand design, friendly staff at all stages of communication with the customer.
