Hot Dipped Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard 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. Usually hot dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
