Color Coated 55% Galvalume Steel Coil AFP/ Non AFP Galvalume Steel , Minimised Spangle , Anti-Finger Print
Introduction:
Galvalume is a product which is very similar to Galvanized steel but with better corrosion resistance(up to 3 times life of galvanized).The supperior properties of galvalume arise from the unique composition(43.5%Zn,1.5%Si,55%AL) of the metallic coating.The galvalume steel coil has uniform thickness ,strong adhesive force , no peeling during processing and molding , and good corrosion resistance.The surface is bright and clean , the size is accurate ,the coil surface ia straight ,the zinc flower is even and beautiful .After its surface is finished ,it is a good substrate for making anticorrosive coating coil. Hot-dip aluzinc steel sheet is substrated on cold rolled steel(CRC)in various strength and specification Coating composition is 55%aIuminum in weight ratio.43 4%zinc.and 1 5%silicon with excellent corrosion and heat resistance performance.
Application range:
