Q:What is hot-dip aluminized zinc steel sheet?

Hot-dip aluminized zinc steel sheet is a coated steel sheet made by applying a double-sided hot-dip aluminized zinc alloy coating to cold-rolled steel sheet as the base material. The alloy composition of the coating is 55% Al, 43.5% Zn, and 1.5% Si by mass percentage.
The physical isolation, electrochemical protection, and trivalent aluminum ion doping of the aluminized zinc coating give aluminized zinc steel sheet excellent corrosion resistance.
Under the same conditions, the service life of aluminized zinc steel sheet is 2-6 times that of ordinary galvanized steel sheet.
