Product Specification

DX51D 24 Gauge Prepainted Galvanized Steel Coil G30 RAL Color for Roofing and Wall Cladding

１．Product Overview

DX51D 24 Gauge Prepainted Galvanized Steel Coil is a color-coated steel product widely used in roofing systems, wall cladding panels, steel structures, and industrial fabrication. Produced from galvanized steel substrate and finished with an organic coating system, it combines corrosion protection with decorative appearance and forming performance.

The product is available in a wide range of RAL colors and is suitable for both architectural and manufacturing applications requiring consistent surface quality.

２．Technical Solution

The galvanized substrate is protected by a zinc coating ranging from 30g/m² to 275g/m². The steel surface is continuously coated and cured to provide adhesion, weather resistance, and color consistency.

DX51D and SGCC grades offer good formability for roll forming, bending, profiling, and sheet fabrication processes. The regular spangle finish provides a traditional galvanized appearance beneath the coating system.
