Galvalume coils

The galvalume coating applied by the continuous hot-dip process is an alloy consisting of approximately 55% aluminium and 45% zinc by weight. Galvalume steel sheet combines the best qualities of aluminium and zinc offering at least two times the corrosion resistance of galvanized. The aluminium-zinc coating provides superior corrosion resistance and heat reflectivity. It also has good bare edge protection and forming qualities. The smooth, silvery metallic spangle appearance makes it attractive in unpainted applications. It is also available in prepainted form.
