１．Product Overview
The 0.12mm DX51D AZ275 Galvalume Corrugated Roofing Sheet is designed for lightweight roofing and wall cladding applications where corrosion resistance and efficient coverage are required. Manufactured from aluminum-zinc coated steel substrate, the corrugated profile improves structural rigidity while maintaining low weight, making it suitable for industrial, commercial, agricultural, and prefabricated building projects.
２．Technical Solution
The sheet is produced from hot-dipped galvalume steel with an aluminum-zinc alloy coating that combines aluminum barrier protection and zinc sacrificial protection. The corrugated design increases load-bearing capacity and installation stability. The passivated surface treatment helps improve resistance to storage staining and enhances handling performance during transportation and installation.
