Hot Dipped Galvanized Steel Sheet In Coils Used In Steel Structural Projects, GI
1. Product profile
Galvanized steel strip coil is also called hot-dip zinc or hot-dipped galvanizing. It is an effective
way of metal anti-corrosion, mainly used in the industries of metal structure facilities. De-rusted
steel is dipped in to 500 °C zinc liquid and coated with zinc which provides corrosion protection.
