GAL180™ steel is the result of an ideal alloy of aluminum and zinc. It consists of aluminum (55%), zinc (43.4% in weight), and silicone 1.6% in weight ratio) so it has both aluminum-unique corrosion-resistance and heat resistance and zinc-unique galvanic behavior.

This aluminium-zinc alloy coated steel product is made with the most ideal combination of the advantages of Zinc (sacrificial anode and alkalinity resistance) and the advantages of AIuminium (durability, heat resistance, and acidity resistance).

Al-Zn alloy galvanized steel product is made through the optimal synergy between the strengths of zinc and aluminum. These strengths are durability, heat resistance, and alkali/acidity resistance. Galvalume steel is used in materials for roofs and walls in construction and residential market.
