Description
Prepainted galvanized steel coil (PPGI) is a new type of composite material made by applying a continuous organic coating to hot-dip galvanized steel sheets—which serve as the substrate—following chemical pretreatment, and then curing the coating through baking. It combines the strength of steel with the decorative appeal and corrosion resistance of the coating, making it a key raw material in industries such as construction, home appliances, and transportation.
