Prepainted Steel Coil
Color coated Steel Coil is mainly divided into three parts: construction, household appliances and transportation. Building is generally used to build the roof, wall and door of industrial and commercial buildings such as steel structure workshop, airport,warehouse and freezer. Household appliances are used in the production of refrigerators and large air conditioning systems, freezers, toasters, furniture, etc. Transportation industry is mainly used for oil pan, automobile interior parts, etc.
PPGI is a product made of cold-rolled steel coil and (aluminum) Galvanized Steel Coil after surface chemical treatment, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. This product is produced by the manufacturer in coils on the continuous production line, so it is also called prepainted steel coil. It not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials.
