Any house, as we know, begins with outer door. It ensures safety and at the same time is "face" of any dwelling. Choosing reliable outer door, it is necessary to know to what parameters it has to correspond that it should be taken into account doors or what locks provide the greatest reliability at its choice.
Instruction
1. Choose outer doors in the large companies. Whatever advantages of door to you painted advertizing agents, whatever photos showed before agreeing to purchase, it is better to look at it "alive". I.e. to estimate reliability of loops, operation of locks, to choose the finishing corresponding to your taste, and it is possible to make it only in showroom where the most part of the range of the company is provided. By the way on its scales it is possible to judge also solidity of the most trading organization.
2. Check documents for the outer doors confirming their quality. The solid and reliable producer to which the reputation is expensive will surely take care of confirmation of quality of the products. Though outer doors are also not subject to obligatory certification, the reliable "players" of this market working not one year have this document. One many more eloquently than advertizing agents various diplomas, awards speak about output quality.
3. Pay attention to quality of cloth. If you not the Italian mafioso, to you to anything massive armored doors. But also too thin material will not approach. The greatest preference is given to outer doors at which thickness of external steel sheet is 2-4 mm. The qualitative door cloth has to be strong, beautiful, reliable and provide fine shumo- and warmly isolation. Besides it has to be supplied with peephole with viewing angle not less than 120 degrees.
4. Learn how many locks are put on door. The reliable model has to have not less than two locks of different type. The more the lock has secrets, the it is more difficult to open it. And if at doors locks suvaldny and, let us assume, bayonet type are put at the same time, it will give it big reliability in fight against any malefactors.
