AZ50 Galvalume Steel Coil (50 g/m²)
High-Performance AZ50 Galvalume Coil with Superior Corrosion Resistance, Heat Reflectivity, and Long Service Life for Roofing, Construction, and Industrial Applications
Galvalume Steel Coil AZ50 (50 g/m²) – High-Performance Aluzinc Coated Steel
Galvalume Steel Coil AZ50 (50 g/m²) is an aluminum-zinc coated steel product manufactured to ASTM A792 standards. The AZ50 designation (0.50 oz/ft², 50 g/m² total coating) provides a balanced layer of 55% aluminum, 43.5% zinc, and 1.5% silicon, offering superior corrosion protection, high heat resistance, and long service life.
Compared with galvanized steel, AZ50 Galvalume delivers up to 6x better corrosion resistance, excellent thermal reflectivity, and reliable formability, making it a preferred choice for roofing, siding, appliances, automotive, and agricultural structures.
Key Features
AZ50 Coating (50 g/m²) – durable aluminum-zinc alloy protection.
Superior Corrosion Resistance – up to 20–30 years service life.
High Heat Resistance – continuous use up to 315 °C, peak 480 °C.
Thermal Reflectivity – reduces cooling loads in roofing applications.
Good Formability & Weldability – suitable for bending, stamping, and fabrication.
