Prepainted Steel Coil: Substrate, Coatings and Properties
Prepainted steel coils, also known as pre-coated steel, color-coated steel coil, or PPGI (pre-painted galvanized iron) coil, have been coated with primer and paint before they are cut, shaped, or formed into final products.
This process ensures a uniform paint application, contributing to the material¡¯s aesthetic and functional properties.
The coils are commonly made from galvanized or Galvalume steel, which provides a rust-resistant foundation, and the pre-applied paint adds an additional layer of protection against environmental factors.
