CGCC DX51D 900MM Pre Painted Corrugated Roofing Sheet Hot Dipped Galvanized Steel Coils

１．Product Overview

CGCC DX51D 900MM pre painted corrugated roofing sheet is used for roofing, wall cladding, structural buildings, commercial construction, household appliance panels, industrial workshops, and general building applications.

The product is made from hot dipped galvanized or galvalume steel substrate with color coated surface. The corrugated profile improves panel rigidity, while the pre painted surface provides decorative appearance and corrosion protection for roofing and wall systems.

２．Technical Solution

The roofing sheet is produced according to JIS G3322 CGLCC, ASTM A792, and EN 10169 DX51D+AZ standards.

The top surface uses 15–20 micron polyester plus 5 micron primer. The back surface uses 5–7 micron or 7–8 micron polyester plus 5 micron primer.

Zinc coating from 50g/m² to 180g/m² supports corrosion resistance for roofing and construction applications. PE, SMP, PVC, and PVDF painting materials can be selected according to weather exposure, surface performance, and project appearance requirements.
