Hot Dipped Gavalume steel coil is a high-performance coated steel product manufactured by hot-dip plating a steel substrate with an alloy consisting of 55% aluminum, 43.4% zinc, and 1.6% silicon. It combines the barrier protection of aluminum and the sacrificial protection of zinc, making it a reliable choice for long-life, low-maintenance applications across various industries.
With excellent corrosion resistance—2 to 6 times better than conventional galvanized steel—and high heat resistance up to 315°C, aluzinc performs well in harsh environments such as coastal areas and high-temperature settings. It also features a sleek silvery metallic finish, good formability, and easy processability, allowing for bending, stamping, and painting as needed.
Widely applied in construction (roofing, wall cladding, frames), automotive parts, home appliances, solar energy systems, and agriculture, aluzinc balances durability, aesthetics, and sustainability, providing cost-effective solutions for both indoor and outdoor projects.
