Hot-Dipped galvanized steel strips greatly resist corrosion and rust, combine utility and beauty. The zinc coating is firmly bonded to the base metal, and the coating of hot dipped galvanized steel strips are often thicker than electro galvanized steel. They are more suitable for heavy duty applications and outdoor exposure.
The zinc coating provides protection against corrosion. Galvanized steel strips can be produced through a continuous hot-dip galvanizing process in which the steel is immersed in a container of molten zinc.
