&Nbsp;    a look at the materials used. High quality aluminum alloy doors and Windows used in the aluminum, oxide film thickness, strength and shall comply with the relevant national standards, wall thickness 1.2 mm, 157 n tensile strength per square meter mm, yield strength to reach 108 Newton per square mm, oxidation film thickness of 10 microns. If you cannot meet the above standards, is poor-quality aluminum alloy doors and Windows, should not be used. &Nbsp;

      the second processing. High quality aluminum alloy doors and Windows, fine processing, installation stress, good sealing performance, switching easily. Poor quality of aluminum alloy door and window blind selection series and specifications for aluminum, processing crude, replaced by sawing and milling, not complying with the requirements for installation, sealing performance is poor, switch freely, not only air leak leaks and glass breakage phenomenon, but encountered strong winds and forces, easy to push and pull parts or glass blown or dropped, and destroy cuts.

Some have only 0.6-0.8 mm wall thickness made of aluminum alloy doors and Windows, the tensile strength and yield strength is much lower than the standard provisions of the State, is not safe to use. In addition, processing of aluminum alloy doors and Windows more self-employed, they do not know the structure and properties of aluminum alloy doors and Windows. In order to reduce the cost of cutting corners, shoddy, disasters, and generally should not be used. The best selection of regular aluminum Windows and doors manufacturer's product.
