Color steel plate is also called pre-coated steel plate. It is based on metal strip steel (such as cold-rolled steel sheet, hot-dip galvanized sheet, galvanized sheet, electro-galvanized sheet, etc.). Through strict process control, various polymer coatings or pastes are applied on its surface. Thickness 0.12-2.0mm, width 600-1500mm. Color precoated steel plate includes galvanized color steel plate (PPGI)and aluminum-zinc (Al-Zn) color steel plate(PPGL).
Pre-painted Galvanized Color steel plate is the most commonly used steel plate for sandwich panels, and the thickness is generally 0.4-0.8mm.The color can be customized according to the needs of the project.
