JIS SGCC SGCH G550 Galvanized Corrugated Roofing Sheet for Construction Roof and

１．Product Overview

JIS SGCC SGCH G550 galvanized corrugated roofing sheet is designed for construction roofing, wall cladding, industrial buildings, warehouses, and interior or exterior decoration systems.

The corrugated profile improves sheet rigidity and installation stability, while the galvanized zinc coating provides corrosion protection for roofing and wall applications. With 0.12-1.2mm thickness, 600-1250mm width, and customized length up to 12000mm, the product can match different building structures and project layouts.

２．Technical Solution

The product is manufactured from galvanized steel substrate and formed into corrugated roofing sheets through roll forming processing.

SGCC and SGCH grades are suitable for common galvanized roofing and cladding applications, while G550 provides higher hardness and panel rigidity. Zinc coating from 30-270g/m² supports different corrosion resistance requirements for construction and industrial environments.

Prepainted, color coated, zinc coated, and hot dipped surface treatment options are available according to appearance, durability, and project specification needs.
