S450 G20 Galvanized Corrugated Roofing Sheet 0.6mm 150g/m² Zinc Coating for Steel Structure Housing

１．Product Overview

S450 G20 galvanized corrugated roofing sheet is designed for steel structure housing, building material applications, roofing systems, and wall cladding projects.

The sheet uses galvanized steel with a corrugated profile to improve rigidity, drainage performance, and installation stability. With 0.6mm thickness, 1000mm width, 1250mm length, and 150g/m² zinc coating, it is suitable for roofing and cladding applications where corrosion resistance and structural stiffness are required.

２．Technical Solution

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

The 150g/m² zinc coating helps protect the steel surface from oxidation and rust in construction environments. Big spangle surface provides a typical galvanized appearance, while skin-passed, non skin-passed, or chromated surface treatment options support different appearance and handling requirements.
