Galvanized steel is a hot-dipped coated metal that provides customers with better resistance to corrosive environments.

To create galvanized steel, cold rolled steel is submerged into a molten zinc bath, known as the hot-dip process (galvanization can also be achieved through continuous galvanizing). When the material is removed from the zinc bath and cooled a reaction to the oxygen in the air occurs. The reaction causes the zinc coating to become part of the steel creating the well-recognized spangled finish.

Hot-Dip Galvanized Steel Coil has excellent performance, possessing ideal comprehensive properties of corrosion resistance, formation and coating. It is produced by passing the steel sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristic
