AZ185 Galvalume Steel Coil (185 g/m²)
Premium AZ185 Aluzinc steel coil with excellent corrosion resistance, heat reflectivity, and long service life for construction, automotive, appliances, and energy industries.
Galvalume Steel Coil AZ185 – 185 g/m² Aluminum-Zinc Coated Steel
Galvalume Steel Coil AZ185 is a premium hot-dip aluminum-zinc alloy coated steel sheet with a coating mass of 185 g/m². The coating consists of 55% aluminum, 43–43.5% zinc, and 1.5% silicon, delivering outstanding corrosion resistance, thermal reflectivity, and extended service life. Compared with AZ70, AZ100, and AZ150, AZ185 provides a thicker protective layer, making it ideal for long-term applications in harsh outdoor, coastal, and industrial environments.
Key Features
Superior Corrosion Resistance – Provides long-lasting durability in marine, humid, and industrial conditions.
High Heat Reflectivity – Reduces heat absorption, helping lower energy costs in roofing and cladding applications.
Excellent Processability – Supports bending, cutting, stamping, welding, and painting for versatile applications.
Extended Lifespan – The 185 g/m² coating layer ensures maximum protection against rust and weathering.
Eco-Friendly Material – 100% recyclable and compliant with global environmental standards.
