Flexible Corrugated Steel Roof Sheets for Warehouses and Special Construction Projects

1．Product Overview

Flexible corrugated steel roof sheets are designed for warehouses, special construction projects, industrial buildings, civil buildings, and workshop roofing systems.

The product uses hot dipped galvalume steel as the base metal and is formed into a corrugated roofing profile. The corrugated structure improves panel rigidity while keeping the sheet lightweight and easy to install. The color coating provides surface protection and architectural appearance for outdoor building applications.

2．Technical Solution

The sheet is produced from CGLCC or DX51D+AZ galvalume steel substrate according to JIS G3322, ASTM A792, and EN 10169 standards.

The AZ coating range is 50–180g/m². The top surface uses 15–20 micron polyester plus 5 micron primer, while 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 warehouse roofing, SMP is selected for improved weather resistance, and PVDF is suitable for stronger UV exposure and longer exterior service.
