PPGI steel coil
galvanized steel coilIn addition to using color-coated hot-dip galvanized/aluminum coil as a substrate,but also can use cold-rolled,hot-dip steel coil and aluminum coil as the substrate.adopting high technology and advanced equipment,the base material to go through degreasing,cleaning,surface treatment film.Organic polymer resin and then coated with primer and top coat consisting of senior coated steel.Fuyuan merged into overall good quality board.the color-coated with a broader applicability,decorative,molding,corrosion resisitance,weather resistance and other characteristic.
