GALVALUME STEEL SHEET (GL)

GALVALUME STEEL SHEET (GL)

Galvalume Steel Sheet_Aluminum-Zinc Alloy Coated Steel Sheets (GL) are galvanized steel sheets with both zinc and aluminum, and is the ideal combination of anti-corrosion and alkali-resistance of zinc, and the durability, heat-resistance, and acid-resistance of aluminum.

The galvanized layer is consisted of 55% of aluminum and 43.3% of zinc and 1.6% of silicon per weight, and 80% aluminum in terms of volume ratio, so while the advantages of aluminum is well preserved zinc prevents the risk of red rust on the surface, a weakness of aluminum, and the product combines the strengths of both materials.
