Red Color Coated Galvalume Corrugated Steel Roof Sheets for Roofing and Wall Cladding

1．Product Overview

Red color coated galvalume corrugated steel roof sheets are designed for roofing, wall cladding, industrial buildings, warehouses, workshops, and commercial construction projects.

The product uses hot dipped galvalume steel as the base material and is coated with an organic paint system. The aluminum-zinc substrate provides corrosion protection, while the red color coating improves appearance, weatherability, and surface durability for exterior roofing applications.

2．Technical Solution

The material is produced from galvalume steel substrate with AZ coating from 50–180g/m². The sheet is then painted and roll formed into corrugated roofing profiles.

The top surface uses 15–20 micron polyester plus 5 micron primer. The back surface uses 5–7 micron or 7–8 micron polyester plus 5 micron primer.

Available paint systems include PE, SMP, and PVDF. PE is suitable for standard roofing applications, SMP provides improved weather resistance, and PVDF is selected for stronger UV resistance and longer outdoor service.
