Galvalume steel coil cold rolled for building , G550 , G450 , G300
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 surface of Galvalume steel coil is bright and clean ,the size is accurate ,the coil surface is straight , the zinc flower is even and beautiful.After its surface is finished , it is a good substrste for making anticorrosive coating plates .It is widely used in various kinds of industry such as construction , light industry , automobile , agriculture , animal husbandry, fishery and business. The construction industry is mainly used in the manufacture of anticorrosive industrial and civil building roof panels , rood grille , etc; the light industry uses its home appliance shell , civil tobacco meat , kitchen utensils , etc; the automobile industry is mainly used for the corrosion resistant parts of cars and so on; the farmers and animal husbandary owners.
It should be used for grain storage and transportation, frozen processing equipment for meat and aquatic products, etc.
