Aluzinc steel sheet

Alu-zinc coated steel (55% aluminum, 43.4% zinc, 1.6% silicon) combines the corrosion resistance of aluminum with the sacrificial protection of zinc. The aluminum-rich surface forms a tough oxide barrier against atmospheric corrosion, while zinc provides galvanic protection at cut edges and scratches. Offering 2 to 4 times the durability of standard galvanized steel, it excels in high-heat reflectivity and long-term outdoor exposure. Widely used in roofing, wall cladding, grain silos, home appliances, and automotive parts, Galvalume delivers a cost-effective balance of longevity and performance for both industrial and residential applications.
