Galvalume is more corrosion resistant than galvanized because of the barrier of protection the aluminum creates. Galvalume is also a thinner steel than galvanized making it a bit more vulnerable to scratches.

The galvalume & aluzinc steel sheet in coil uses the cold-rolled steel sheet as a substrate and solidified by 55% aluminum, 43.4% zinc and 1.6% silicon at 600 °C. It combines the physical protection and high durability of aluminum and the electrochemical protection of zinc. It is also called aluzinc

Hot Dipped Galvanized Steel CoilsHot Dipped Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintabi
