Galvanized sheet refers to a steel sheet with a layer of zinc on the surface. Galvanizing is a frequently used economical and effective anti-rust method, and about half of the world's zinc production is used for this process.

Alu-zinc sheet has a 55% aluminum-zinc alloy coating on the surface. The surface of the galvanized sheet presents a unique smooth, flat, and gorgeous starlight, and the basic color is silver-white. The special coating structure gives it excellent corrosion resistance. The normal service life of the galvanized sheet can reach 25 years, and the heat resistance is very good. It can be used in a high temperature environment of 315℃; the coating and paint film have good adhesion, good processing performance, and can be stamped, sheared, welded, etc.; the surface conductivity is very good.
