Another category of steel doors – the so-called "elite" steel door. Typically, this the doors of foreign manufacture (European, for example GERDA), which are expensive forms of external and internal finishes (MDF, veneer), as well as expensive locks, accessories (also imported). To the weak sides of these doors should be attributed to considerable cost – from $ 1500 and great delivery time. The latter category – it is the metal doors of domestic manufacturing. They are optimal in terms of price and quality (from U.S. $ 350). Similar between is at first glance thanks to finishing materials (vinil. leather, hardboard, mdf, veneer., polymer coating), they are quite different in structure and internal devices.

First of all, was isolated and welded tselnognutye Box Design and the door leaf. The level of burglary, manufacturability and appearance wins tselnognutye door. Used a loop can be open or hidden. Open loop is opened 180 degrees, but their level of burglary is much lower than that of the hidden (the opening angle of about 110 degrees). The thickness of the hidden loops must be at least 6 millimeters to door leaf is not slack with time.

Door leaf must should be strengthened with additional system of stiffeners, protivootgibochnymi corners, and insulated (Isover, min. wadding, foam). Scope of locks need to be strengthened against the plate, drilling, strengthen the special canisters under lock and key. Have to rely on those producers who can provide you with complete and clear information on the design of manufactured doors. Thus, the door of domestic production is better to choose from tselnognutogo profile, hidden hinges and a powerful "sound" design. Weak side of the door, perhaps, is their appearance (for doors decorated with vinyl. Skin), "bored" with the Soviet era, although this drawback can be minimized if we choose as finishing mdf, veneer, particleboard (optional 120-300 dollars). When considering the strengths of the metal doors of domestic production, they are: 1. optimal the ratio of price and quality 2. a wide range of materials used, locks. 3. production according to individual customer's sizes. 4. guarantee the local manufacturer. Market for domestic steel doors sufficiently representative, thanks to the choice of such doors can rely on the experience and reputation of the manufacturer, the professionalism of the sales and installation teams.

"It seems to be toned and not (because we paid coating on the glass). BUT! The coating should limit "VISIBILITY" with the driver's seat. What is "Visibility"? VISIBILITY – The property of the vehicle, determined by the driver to see a workplace outside the space vehicle. Connect with other leaders such as Samsung here. That is, in fact it is the angle within which we can see space! And the visibility – it's not visible – the eye's ability to perceive an object, the visibility is determined by the ratio of the contrast of the object with the background to the magnitude of the threshold or the smallest discernible eye contrast. That Thus, if the inspector says that you will not see the post at night, for 50 yards, he can and will be right, only it's not deteriorating visibility is reduced visibility. If you were nailed for half a glass veneer, it would be deterioration in visibility. Are investigated further. Written that are allowed to apply tinted windows, and the way they do not specify tint! And so the only thing that we have violated, the percentage of tinting specified in the guest (Windscreen light transmission should be at least 75% front side windows of at least 70%, the rest is not specified).

But we broke it? Otherwise you would not read it. Thus, to prove your guilt DPS officer should measure the light transmission of your tinted glasses a special device (which also must be certified and have an annual calibration). In accordance with Annex N 1 to the Order of the Interior Ministry on December 7, 2000 N 1240 "Manual of Technical Supervision State Inspection Road Safety Ministry of Internal Affairs of the Russian Federation", subject to the supervision of traffic control for construction and technical condition of vehicles can be carried out on stationary posts and police check posts, checkpoints, vehicles. All this means only one thing: to get you for tinted can (a fine of 100 rubles.), but only for the above positions in the presence of technical means for verification. That is, the city can ride safely, unless of course you have time and desire to prove all this DPSnikam. The original of this and my other articles can be read on
