Corrosion Resistant Aluminum Steel Coil 0.5mm-3mm Thick For Roofing Automotive

Aluminum Steel Coil 0.5-3mm Thick ASTM Certified Corrosion-Resistant For Roofing Automotive

Aluminum Steel Coil is a revolutionary hybrid material combining the lightweight benefits of aluminum with the structural strength of steel. Designed for roofing and automotive applications, this ASTM A792/A809-certified coil features a 55% aluminum-zinc alloy coating (Galvalume® equivalent) for unmatched corrosion resistance, heat reflectivity, and durability. Available in 0.5–3mm thicknesses and custom widths, it is engineered to withstand harsh weather, UV exposure, and chemical exposure while reducing lifecycle costs.

Key Selling Points:

Superior Corrosion Resistance: 55% Al-Zn coating outperforms traditional galvanized steel in salt spray tests (ASTM B117).
Lightweight & Strong: 20% lighter than pure steel, with tensile strength up to 550 MPa.
Heat Reflectivity: Reflects 80% of solar radiation (ASTM E424), reducing cooling costs for buildings.
Easy Fabrication: Compatible with roll forming, stamping, and welding processes.
Eco-Friendly: Recyclable material compliant with LEED and BREEAM standards.
