Customized RAL Color PVDF Prepainted Steel Sheet DX51D AZ Coated for Roofing and Cladding

1．Product Overview

Customized RAL color PVDF prepainted steel sheet is designed for roofing sheets, wall cladding systems, steel structure buildings, and exterior architectural panels requiring long-term weather resistance and stable surface appearance.

The product uses hot dipped galvanized steel or galvalume steel substrate combined with a continuous color coating process. The painted surface improves corrosion resistance, UV durability, and appearance consistency for outdoor applications.

2．Technical Solution

The steel sheet combines galvanized or galvalume substrate with primer and finish coating layers.

Available coating systems include PE, SMP, and PVDF. PVDF coating provides improved UV resistance and outdoor durability for long-term exterior exposure applications.

The standard coating structure uses 25±5 micron top coating and 7±2 micron back coating to maintain coating consistency and forming performance during fabrication.

The product supports customized RAL colors for roofing, wall cladding, and architectural panel projects.
