1.0mm RAL 1030 Prepainted Steel Sheet DX51D 1250mm Width for Roofing and Wall Cladding

1．Product Overview

1.0mm RAL 1030 prepainted steel sheet is designed for roofing sheets, wall cladding panels, steel structure buildings, and exterior architectural applications requiring stable color appearance and outdoor durability.

The product combines hot dipped galvanized steel or galvalume steel substrate with a continuous coating process. The painted surface improves corrosion resistance, UV durability, and appearance consistency for long-term exterior use.

2．Technical Solution

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

Available coating systems include PE, SMP, and PVDF. PE coating is suitable for standard roofing and wall applications. SMP coating improves weather resistance for outdoor exposure. PVDF coating provides stronger UV resistance and improved long-term color stability.

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