The transformation of the house into a fortress is best start with a solid door. Doors that can not hack, not yet invented. But to crack the safe door will take time, effort and noise. The main thing that this time enough to arrive at the place of service.
The producers there are several methods of manufacturing steel doors, even as they lead a special webinar . Depending on the method of manufacture and the cost depends on the door. But if you value the security of your premises then we go about saving should not be. Most manufacturers of welded parts of frame and then welded it to the steel sheets. Moreover, some manufacturers on the technology provided ribs, and some do not. It is necessary to consider when buying a door. If the ribs are absent, then take the door is not worth it. Sagging and misalignment during operation is guaranteed. And plus this version is not very reliable. Using this technology produce a budget option for steel doors. Its cost does not exceed 18 000 rubles. Safety of such manufacturers is in the background.
In the manufacture of more reliable and solid doors are used flexibly. Initially, a sheet metal bend rather complicated profile and increase his ribs. It is for this technology and these must be made safe and secure door. Then welded to an increased profile sheeting. Through the use of spot welding is no bias at the door will not. This door will cost more than the budget option. But on the strength of these doors many times the bypass budget.
Despite the method of manufacturing the door need to pay attention to the thickness of the cladding. If it does not exceed 1 mm, take the door is not worth it. It can open the can opener. The thickness should be between 1,2-2,5 mm. And the thicker, the better. Determine the thickness of the metal can on a combination of joints or on the bottom, where the bending. Even in the eyes can determine how thick the metal. Still need to pay attention to the framing of the door. It should be on the order of the thickness of the doors themselves to securely hold them myself.
It turns out, as described in many articles on copywriting , stock exchange, the main indicator of the reliability of the door is the thickness of its outer skin, a standard set of locks and burglar elements from different manufacturers almost the same. But this does not mean that it should not be paying attention.
