CGCC 4 x 8 Corrugated Metal Sheets GI Corrugated Roofing Sheet for Industrial and Civil Buildings

1．Product Overview

CGCC corrugated metal sheets are used for industrial and civil buildings, roofing systems, wall cladding, structural use, commercial buildings, household appliance panels, warehouses, workshops, and general construction applications.

The product is made from color coated galvanized or galvalume steel substrate and formed into corrugated roofing sheets. The 76mm wave width and 17mm wave height improve panel rigidity, while the color coated surface supports corrosion resistance and building appearance requirements.

2．Technical Solution

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

Zinc coating from 50g/m² to 180g/m² supports corrosion resistance for industrial and civil building applications. PE, SMP, PVC, and PVDF painting materials can be selected according to weather exposure, surface durability, and architectural appearance requirements.

Bright and matt finishing are available for different roof and wall design requirements.
