Galvalume sheet:
Galvalume Steel Sheet is carbon steel sheet coated with aluminum-zinc alloy by a continuous hot dipped progress .The nominal composition is 55% aluminum and 45% zinc.
A small but important addition of silicon is included in the coating alloy. It is added not to enhance the corrosion performance,
but to provide good coating adhesion to the steel substrate when the product is roll-formed, drawn, or bent during fabrication.
