30–275g/m² Galvanized Corrugated Roofing Sheet 600–1250mm Steel Roof Panel

１．Product Overview

Galvanized corrugated roofing sheet is a hot dipped galvanized steel roof panel used for industrial buildings, civil buildings, warehouses, prefabricated houses, steel structures, mobile houses, container manufacturing, household appliances, furniture, vehicles, and vessel manufacturing.

The corrugated profile improves sheet stiffness, while the galvanized zinc coating provides corrosion resistance for roofing, wall cladding, and exterior building applications. With 30–275g/m² zinc coating and 600–1250mm width options, the product is suitable for both standard roofing projects and customized construction requirements.

２．Technical Solution

The product uses galvanized steel substrate and corrugated roll forming technology. The zinc coating protects the steel surface from oxidation and rust, while the wave profile improves rigidity and water drainage performance.

SGCH full hard material provides higher strength and sheet stiffness for roofing applications. Optional materials such as DX51D, DX52D, S350GD, and S550GD can be selected according to forming requirements, strength level, and project specification.
