Structural 76mm Pre Painted Corrugated Roofing Sheet GI Corrugated Sheet with Matt Finishing

Structural 76mm Pre Painted Corrugated Roofing Sheet GI Corrugated Sheet with Matt Finishing

１．Product Overview

Structural 76mm pre painted corrugated roofing sheet is used for roofing, structural cladding, wall panels, commercial buildings, industrial workshops, warehouses, household appliance panels, and general construction applications.

The product is manufactured from color coated galvanized or galvalume steel substrate. The 76mm wave width and 17mm wave height provide corrugated rigidity, while the matt finishing surface supports a lower-gloss architectural appearance 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 corrugated profile improves panel stiffness for roofing and structural applications. Zinc coating from 50g/m² to 180g/m² supports corrosion resistance for common building environments.

Painting materials include PE, SMP, PVC, and PVDF. Bright or matt finishing can be selected according to architectural appearance and project requirements. The matt surface is suitable for buildings requiring reduced reflection and a more consistent visual finish.
