The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminized sheet, and it is a continuous molten coating process. The galvanized steel sheet with 55% aluminum-zinc alloy coating has better corrosion resistance than galvanized steel sheet of the same thickness when exposed to the same environment on both sides. The 55% aluminum-zinc alloy coated aluminum-zinc steel sheet not only has good corrosion resistance, but also the color-coated products have excellent adhesion and flexibility.DX52D+AZ/DX51D+AZGalvalume/galv......
