Z30-Z275 Zinc Coating Al-Mg-Mn Prepainted Galvanised Steel Coil
Introduction:
It is made by taking hot galvanized sheet and zinc-iron alloy hot galvanized sheet as the substrate through surface pretreatment, coating one or more layers of liquid coating by roll coating, baking and cooling. With GI as base metal,after pretreatment(degrease and chemical treatment)and liquid dope with several layers of color,then after firing and cooling,finally the plate steel is called pre-painted galvanized steel(PPGl).Pre-painted gaIvanized steeI is good capable of decoration,molding,corrosion resistance.
Galvanized Sheet:
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.
Cold Rolled Sheet:
Cold sheet has excellent type and surface quality and mechanical property indexes meeting customer demands. It is widely used for galvanized substrate, home appliances, tubbing, automobile, building, enamel, and other industries.
