Color Coated Aluminium Coil Prepainted Galvalume Steel Coil ASTM A755M

Color Coated Aluminium Coil Prepainted Galvalume Steel Coil ASTM A755M

With GI (aluzinc) as base metal, after pretreatment (degrease and chemical treatment) and liquid dope with several layers of color, then after firing and cooling, finally the plate steel is called pre-painted galvanized (aluzinc) steel. Pre-painted galvanized steel is good capable of decoration, molding, corrosion resistance. It generally displays superior workability, durability and weather resistance.
