0.18mm ASTM A792 Prepainted Steel Coil RAL 6019 PE Coated CGCC for Roofing and Building Panels

１．Product Overview

0.18mm ASTM A792 Prepainted Steel Coil is a lightweight color-coated steel solution designed for roofing panels, wall cladding, building components, and light industrial fabrication. Manufactured on a galvanized steel substrate and finished with a PE coating system, the product provides a balance of corrosion resistance, formability, and decorative appearance.

The RAL 6019 finish offers a clean architectural appearance suitable for residential, commercial, and agricultural construction projects.

２．Technical Solution

The steel substrate is protected by a 60g/m² zinc coating that provides sacrificial corrosion protection. A PE (Polyester) coating system is applied to the surface to improve weather resistance, color stability, and surface durability.

The coating structure is designed to support roll forming, bending, and fabrication processes while maintaining coating adhesion and appearance consistency. The product can be manufactured according to JIS G3312, ASTM A792, GB/T 12754, and EN 10169 related coating requirements.
