0.31mm CGCC Z100 PVDF Prepainted Steel Coil RAL5894 for Roofing and Building Panel Applications
0.31mm CGCC Z100 PVDF Prepainted Steel Coil RAL5894 for Roofing and Building Panel Applications
１．Product Overview
0.31mm CGCC Z100 PVDF Prepainted Steel Coil is a color coated galvanized steel product used for roofing panels, wall cladding, steel structure buildings, vehicle components, furniture panels, and electrical equipment applications.
The product uses CGCC substrate with 100g/m² zinc coating and PVDF paint system. The 0.31mm thickness supports lightweight forming and panel fabrication, 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 100g/m² zinc coating. This metallic coating improves corrosion resistance for building and industrial applications.
The top surface uses 10 Micron Polyester + 5 Micron Primer to improve coating adhesion and surface appearance. The back surface uses 5–7 Micron Primer to improve reverse-side protection during storage, transportation, forming, and installation.
PVDF coating is suitable for applications requiring better weather resistance, UV resistance, and long-term color stability than general polyester coating systems.
