CGCC DX51D Prepainted Corrugated Steel Roof Sheets in White Red Blue RAL Colors for Roofing and Wall Cladding

CGCC DX51D Prepainted Corrugated Steel Roof Sheets in White Red Blue RAL Colors for Roofing and Wall Cladding

1．Product Overview

CGCC DX51D prepainted corrugated steel roof sheets are designed for roofing, wall cladding, building decoration, workshops, warehouses, and light construction projects.

The product uses color coated steel sheet formed into a corrugated roofing profile. The zinc coating provides substrate protection, while the painted surface supports weather resistance, color consistency, and architectural appearance. White, red, blue, and customized RAL colors are available for different project requirements.

2．Technical Solution

The sheet is produced from prepainted galvanized steel substrate and formed into a corrugated profile for roofing and wall panel applications.

The coating structure includes a primer layer and finish paint layer. The top surface uses 10–20 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 polyester, SMP, and PVDF. Polyester is suitable for standard roofing projects, SMP is used for improved weather resistance, and PVDF is selected for stronger UV resistance and longer exterior exposure.
