Aluzinc Steel Coils (55% Al-Zn)

Our flagship product is steel coils coated with an alloy consisting of 55% aluminum, 43.4% zinc, and 1.6% silicon (Aluzinc/Galvalume). This aluminum-zinc coating provides significantly enhanced corrosion resistance—potentially offering 2–4 times the service life of standard galvanized steel under suitable conditions—along with excellent heat reflectivity and a bright spangle finish. These properties make it ideal for roofing, cladding, and appliances, particularly in harsh coastal and desert environments. Between 2025 and 2026, we supplied approximately 4,000 metric tons of this product to customers across the Middle East.
