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

Product Specification

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.
