Prepainted steel coil

Prepainted steel coil, also known as Pre-coated steel coil or Color-coated steel coil, is a type of steel product that has been coated with a layer of paint on a galvanized steel substrate (PPGI) or a galvalume steel substrate (PPGL), offering exceptional corrosion resistance and an aesthetically pleasing finish. This additional coating not only protects the steel from environmental factors but also allows for a variety of colors and textures, enhancing its visual appeal and versatility.
