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

１．Product Overview

JIS G3302 SGCC galvanized corrugated roofing sheet is manufactured for roofing, wall cladding, ceiling, fence, and general construction applications. The corrugated structure improves panel rigidity and drainage performance while maintaining lightweight installation advantages.

Produced with 60-275g/m² zinc coating and 0.14mm-1.5mm thickness, the sheet provides corrosion resistance for industrial buildings, warehouses, steel structures, mobile houses, and large-span construction projects.

２．Technical Solution

The product uses SGCC galvanized steel substrate processed through corrugation forming technology. The galvanized coating helps reduce oxidation and rust under outdoor exposure conditions.

The 76mm wave width and 17mm-17.5mm wave height improve structural strength and water drainage efficiency. Regular spangle and minimum spangle surface finishes are available according to appearance and application requirements.
