１．Product Overview

SGCC SGCH G550 galvanized corrugated roofing sheet is a hot dipped galvanized steel roofing product used for industrial buildings, civil buildings, warehouses, steel structure housing, prefabricated houses, and container applications.

The galvanized zinc coating provides corrosion resistance, while the corrugated profile improves sheet stiffness, drainage performance, and installation stability. With 0.14–1.5mm thickness and multiple length options including 1500mm, 3005mm, and 3600mm, the product is suitable for different roofing and wall cladding projects.

２．Technical Solution

The product uses hot dipped galvanized steel coil as the substrate and is formed into corrugated roofing sheets through roll forming.

SGCC and SGCH are suitable for standard galvanized roofing applications, while G550 material provides higher hardness and rigidity for roofing systems requiring improved structural stiffness. Zinc coating from 30–275g/m² can be selected according to outdoor exposure and corrosion resistance requirements.
