A look at the materials used. High quality aluminum floor mats used in aluminum, thickness, strength and oxidation film, should comply with the relevant provisions of national standards, should be 1.2 mm wall thickness, tensile strength reached 157 Newtons per square millimeter, the yield strength to reach 108 Newtons per square millimeter, the thickness of the oxide film should reach 10 microns. If you reach the above criteria, is of poor quality aluminum windows and doors, can not be used.

Second look processing. High quality aluminum floor mats, fine processing, installation pay attention, good sealing performance, switch freely. Poor quality aluminum windows and doors, aluminum blind selection series and specifications, processing shoddy, to replace the saw milling cutter is not required for installation, sealing performance is poor, the switch does not ease, not only leakage occurs glass leaks and burst phenomenon, and in case to strong winds and external, easy to push and pull off some or glass blowing or touching down, destroy things hurt.

Third, look at the price. In general, high-quality aluminum floor mats because of high production costs, poor quality mat aluminum prices to be higher by about 30%. Currently processing aluminum floor mats are more self-employed, they do not know the structural characteristics of aluminum floor mats and performance. In order to reduce the cost of cutting corners, shoddy, larger product hazards, generally should not be used. The best selection of regular aluminum mats manufacturers of products.
