Hot-dip galvanizing is the most common and effective process measure in steel anticorrosion methods. In the construction industry, light steel keel, building floor, corrugated board, rolling door, etc. Used in various industrial and civil buildings; In household appliances and light industry, it is used for the shell and bottom plate of various household appliances; Galvanized steel plates are widely used in light industry, power supply, automobile and construction industries. In the automobile industry, it is used for automobile body, shell, inner plate, bottom plate and so on.
The main advantage of hot-dip galvanized aluminum alloy coating (coating contains 5%Al, 95%Zn and trace rare earth elements) is that the coating has good plasticity and adhesion, so the corrosion resistance before and after deformation remains unchanged, and its atmospheric corrosion resistance is much higher than that of conventional hot-dip galvanized, which has good coating performance and can keep the combination of alloy layer and coating stable for a long time.
