JIS G3302 SGCC Galvanized Corrugated Roofing Sheet with 275g/m² Zinc Coating

１．Product Overview

JIS G3302 SGCC galvanized corrugated roofing sheet is designed for roofing, wall cladding, ceiling, fence, sandwich panel, and container plate applications. The corrugated profile improves sheet rigidity and drainage performance, while the galvanized surface provides corrosion protection for construction environments.

With 0.14mm-1.5mm thickness, 650mm-1050mm effective width, and 60-275g/m² zinc coating, the product is suitable for industrial buildings, civil buildings, warehouses, large-span steel structure housing, and interior or exterior decoration projects.

２．Technical Solution

The sheet is produced from SGCC galvanized steel and formed into a corrugated roofing profile. The zinc coating protects the steel substrate from oxidation and rust, supporting outdoor roofing and wall system performance.

Regular spangle and minimum spangle surfaces are available for different appearance requirements. The 76mm wave width and 17mm-17.5mm wave height help improve overlap installation, rainwater drainage, and panel stability.
