60-275g/m² Zinc Coating SGCC Galvanized Corrugated Roofing Sheet JIS G3302

１．Product Overview

SGCC Galvanized Corrugated Roofing Sheet is manufactured according to JIS G3302 and designed for roofing, wall cladding, ceiling, and fencing applications. The product combines galvanized corrosion protection with a corrugated profile to provide structural rigidity and long-term outdoor durability.

With zinc coating options from 60g/m² to 275g/m² and thicknesses ranging from 0.14mm to 1.5mm, these roofing sheets are widely used in industrial buildings, warehouses, workshops, agricultural facilities, and steel structure projects.

２．Technical Solution

The roofing sheet is produced from SGCC galvanized steel substrate and processed through roll forming to create a corrugated profile with a 76mm wave width and 17-17.5mm wave height.

The hot-dip galvanized coating forms a protective barrier against moisture and atmospheric corrosion. Regular spangle and minimized spangle surfaces are available to meet different appearance requirements.
