Product Introduction of Coating Business Division
Color Coated Sheet:
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. The used coatings including polyester, silicon modified polyester, high-durability polyester, polyvinylidene fluoride, epoxy and high corrosion-resisting coating are widely used for building, transport, home appliances, solar energy, furniture, etc. It is mainly used as the side door plate of refrigerators, and shell of DVDs, air conditionings, freezers, and washing machines.
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.
