１．Product Overview

The 0.25mm DX51D AZ275 Galvalume Corrugated Roofing Sheet is designed for roofing, wall cladding, and housing panel applications.

Manufactured from aluminum-zinc coated steel, it combines lightweight construction, corrosion resistance, and structural durability. The corrugated profile improves rigidity, making it suitable for residential, commercial, agricultural, and industrial building projects.

２．Technical Solution

The roofing sheet is produced from hot-dipped galvalume steel coated with an aluminum-zinc alloy layer. This coating system provides aluminum barrier protection and zinc sacrificial protection, improving long-term resistance to atmospheric corrosion. The corrugated design increases strength and load distribution while maintaining low weight for easier installation and transportation.
