Hot Dip Galvanized Steel Sheet

Description:
This kind of hot dip galvanized steel sheet, also referred to as galvanized steel coil, is mainly used in machinery fields, light industry, construction sector, transportation field, chemical industry, and home appliances.

It can be made by coating the zinc onto the surface of cold-rolled steel strip by the means of continuous hot dip. Compared with cold rolled sheet and ordinary galvanized sheet, this kind of galvanized steel sheet has superb surface, better corrosion resistance, and better moisture resistance.

Technical Parameters:
Thickness(mm):0.15-0.8
Width(mm):900 -1250
Max. zinc content(double-side g/m2):150
Inner diameter:508mm
Weight of sheet coil:3-5ton
Surface structure: zero zinc spangle/small zinc spangle / normal zinc spangle
Surface treatment: Fingerprint resistant, environmental passivation, oiling, finishing
