How to select aluminum plate quickly?
At first glance, the aluminum plate thickness, strength and oxide film used for high-quality aluminium alloy anti-skid board should meet the relevant national standards. The wall thickness should be over 1.2 mm, the tensile strength should reach 157 Newtons per square meter, the yield strength should reach 108 Newtons per square millimeter, and the oxide film thickness should reach 10 micrometers. If it fails to meet the above standards, it is inferior aluminium alloy doors and windows, can not be used.
Second, look at the processing, high-quality anti-skid aluminum alloy plate, fine processing, installation, sealing performance is good, and the switch is free. Poor quality aluminium alloy doors and windows, blindly select series and specifications of aluminium profiles, rough processing, sawing instead of milling, do not meet the requirements of installation, poor sealing performance, unsound switches, not only leakage of wind and rain and glass cracking, but also encounter strong wind and external forces, easy to push and pull parts or glass blow down or Collision, destruction and injury.
Looking at the aluminum plate price, in general, the cost of high-quality aluminium alloy antiskid plate is about 30% higher than that of low-quality aluminium alloy antiskid plate because of its high production cost. At present, there are many individuals who process the aluminum alloy anti-skid plate. They do not know the structural characteristics and performance of the aluminum alloy anti-skid plate. In order to reduce the cost of jerry-building and reduce material consumption, it is generally unsuitable to adopt the second-best products, which have greater hidden dangers. It is better to choose the products of the normal aluminium alloy anti-skid plate manufacturer.
