1220mm Hot Dip Galvanized Steel Plate Hard Sheet

Hot-dip Galvanized Steel Sheet,Hard Sheet,Galvanized Steel Coil

As a new product of huiyi , Galvalume (abbreviation:GL steel) is hot plating on the surface of steel plate with Al55%,Zn43.5%,Si l.5% ,the surface is smooth,has a good rsistance to atmospheric corrosion,heat resistant oxidation.Hot galvanized sheet and alloying galvanized sheet have excellent performance, ideal combination property including corrosion resistance, formation and coating, and are mainly used for building, automobiles, metallurgy, and electrical equipment. Galvanized sheet is mainly used for making roof, door and window, roller shutter door, and suspended skeleton in building industry, vehicle shell, chassis, door, trunk lid, oil tank and fender in auto industry, steel sash blank and color coated sheet substrate in metallurgy industry, and refrigerator base, shell, refrigerating chamber, kitchen equipment and other parts in electrical equipment industry.Hot-dip galvanized steel sheets (GI) are 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. GI has a thicker galvanized layer which has excellent anti-corrosion qualities, and is the type of steel sheet used most commonly.
