Teach you to choose the correct aluminum alloy skid plate
[China Aluminum Network] to see the use of materials. The aluminum profiles used in high-quality aluminum alloy skid plates, thickness, strength, and oxide film shall comply with relevant national standards. The wall thickness shall be 1.2 mm or more, and the tensile strength shall be 157 N/m2. The yield strength shall be achieved. At 108 Newtons per square millimeter, 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, see processing. High-quality aluminum alloy anti-skid plate, fine processing, installation stress, good sealing performance, easy to switch. 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.
Three to see the price. Under normal circumstances, high-quality aluminum alloy anti-skid plates have high production costs and the price is about 30% higher than inferior aluminum alloy anti-skid plates. 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.
