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.

Customized sheet length, effective width, wave width, wave height, color, painting material, and packing method can be supplied according to project requirements.

６．Advantages

• 76mm wave width and 17mm wave height improve roofing sheet rigidity.
• Matt finishing surface provides a lower-gloss appearance for architectural roofing and wall systems.
• 50–180g/m² zinc coating supports corrosion resistance for building applications.
• PE, SMP, PVC, and PVDF paint systems support different weather exposure and surface performance needs.
• Multiple effective widths support different roofing layouts and installation requirements.
• Standard export seaworthy packing supports container shipment and long-distance transport.

７．How to Choose

• Choose matt finishing when the project requires reduced surface reflection and a softer visual appearance.
• Choose PE coating for common roofing and construction applications.
• Choose SMP or PVDF coating when better weather resistance is required.
• Choose thicker sheets when higher structural rigidity is needed.
• Choose higher zinc coating when the project requires stronger corrosion resistance.
• Choose customized RAL color or customer sample color according to roof and wall design.
• Confirm thickness, width, effective width, zinc coating, paint type, color, wave profile, and packing method before production.
