Pre-painted steel coil(PPGI,PPGL)

is the coil coated steel sheet (galvanized, zincalumed, cold plate, etc.) after surface chemical treatment (degreasing, phosphating, and chromium hydrochloric acid passivation) and coated (roller) with coatings, again baking to forming. It has both the mechanical strength of steel plate and easy molding performance, and the good decorative performance and corrosion resistance. Color coated plate has strong layer adhesion which could keep fresh color for a long time, so it is widely used in building, home appliances, home furniture, public facilities and transportation fields.
