0.35mm CGCC Z180 Prepainted Steel Coil RAL 5236 for Roofing and Building Panel Applications

１．Product Overview

0.35mm CGCC Z180 Prepainted Steel Coil is a color coated galvanized steel product used for roofing panels, wall cladding, steel structure buildings, furniture components, vehicle parts, and electrical equipment panels.

The product uses CGCC substrate with 180g/m² zinc coating and PE coating system. The 0.35mm thickness supports lightweight panel forming, while the pre-painted surface provides corrosion protection, decorative appearance, and reduced secondary painting work.

２．Technical Solution

The galvanized steel substrate is protected by 180g/m² zinc coating. This metallic coating provides corrosion resistance for building and industrial applications.

The top surface uses 10 Micron Polyester + 5 Micron Primer to support coating adhesion and surface appearance. The back surface uses 5–7 Micron Primer to improve reverse-side protection during storage, transportation, forming, and installation.

PE coating is suitable for general roofing, wall panel, and building material applications where balanced appearance and processing performance are required.
