Hot Dipped Corrugated Roof Panels with 76mm Wave for Roofing and Wall Cladding

1．Product Overview

Hot dipped corrugated roof panels are designed for roofing, wall cladding, industrial buildings, warehouses, workshops, container-related panels, and light construction projects.

The product uses hot dipped galvalume steel as the base metal and is formed into a 76mm wave corrugated profile. The AZ coating provides corrosion protection, while the coated surface supports weather resistance and stable appearance for outdoor applications.

2．Technical Solution

The roof panel is produced from CGLCC or DX51D+AZ galvalume steel substrate according to JIS G3322, ASTM A792, and EN 10169 standards.

The AZ coating range is 50–180g/m². The top surface uses 15–20 micron polyester plus 5 micron primer, and the back surface uses 5–7 micron or 7–8 micron polyester plus 5 micron primer.

Available paint systems include PE, SMP, and PVDF. PE is suitable for standard roofing and wall applications, SMP is selected for improved weather resistance, and PVDF is suitable for stronger UV exposure and longer exterior service.
