Language Selection:
Taking high quality cold rolled coil or hot dip galvanized steel coil or galvalumed steel coil as basic plate, the steel plate passes pretreatment(degrease and chemical treatment), liquid dope with layers of color, firing and cooling lines to become pre-painted galvanized steel coil. It displays great workability, durability and weather resistance and always uses for decoration and corrosion resistance, like home appliance cover and roof plate.
