Color Coated Steel Coil

Color Coated Steel Coil | PPGI & PPGL Prepainted Steel

Color coated steel coil, also known as pre-painted steel coil (PPGI/PPGL), is a high-quality steel product coated with organic paints or protective films on its surface. It is produced by applying a color coating on galvanized steel coil or galvalume steel coil, combining the superior corrosion resistance of zinc/aluminum coatings with the decorative and protective properties of organic paints.

With its wide range of colors, excellent surface finish, and long-lasting durability, color coated steel coil has become a preferred material in the construction, home appliance, transportation, and furniture industries. The product not only enhances the aesthetic appearance of buildings but also provides reliable weather resistance, UV resistance, and chemical resistance, ensuring stable performance in harsh environments.
