The surface of aluminum -zinc plate is characteristic of smooth, flat and luxuriant star flower, the primary color is silver white.
Special coating structure makes it has excellent corrosion resistance. The noemal service life of aluminum-zinc plate is up to 25 A, the heat resistance is very good, can be used in 315 c high temperature environment, The coating ang film have good adhesion, has good processing performance, can be stamping, shearing,welding, etc. The surface conductance is very good.
The coating is composed of 55% aluminum,43.4%zinc and 1.6% silicon by weight ratio. The production process of aluminum zinc plate is similiar to that of galvanized steel plate and aluminum plate, which is a continuous melting coating process. The 55% al -zinc-plated al -zinc-plated steel has superior corrision resistance when exposed to the same environment on both sides compared with the galvanized steel of the same thinkness.
