[China Aluminum Industry Network] A look at materials, aluminum profiles used in high-quality aluminum alloy skid plates, thickness, strength and oxide film, etc., should comply with the relevant national standards, wall thickness should be 1.2 mm or more, tensile strength Millimeters of 157 Newtons per square metre, the yield strength must be 108 Newtons per square millimeter, and the thickness of the oxide film should reach 10 microns. If it fails to meet the above criteria, inferior aluminum alloy doors and windows cannot be used.
Second, look at processing, high-quality aluminum alloy skid plate, fine processing, installation stress, good sealing performance, switch freely. Inferior quality aluminum alloy doors and windows, blind selection of aluminum profiles and specifications, rough processing, and saw cutting instead of milling, not installed as required, poor sealing performance, switches are not comfortable, not only leakage of air leakage and glass burst phenomenon, but also To strong winds and external forces, it is easy to scrape or fall off the push-pull part or glass, destroying things and hurting people.
Third, look at the price, under normal circumstances, high-quality aluminum alloy skid plate due to high production costs, the price is about 30% higher than the inferior aluminum alloy skid plate. At present, there are many self-propelled aluminum alloy skid plates, and they do not understand the structural characteristics and performance of the aluminum alloy skid plate. In order to reduce the cost of cutting corners, shoddy products, the hidden dangers of the product is generally not suitable. It is better to use the products of regular aluminum alloy anti-skid plate manufacturers.
