hot-dip galvanized steel
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 characteristics. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
With carbon structural steel or low alloy steel, pure zinc coating, zinc-iron alloy coating, S280GD+Z hot-dip galvanized steel sheet for appliances are featured with strong coating adhesiveness, high erosion-resistance, accurately controlled zinc coating thickness, high size precision, flat profile and good mechanical, processing and welding performance. They can be used for making outside and inside plates for home appliances.
