ASTM A755 PPGI Coil Prepainted Steel Coil Ppgi Color Coated Sheets
Color coated steel coils, also known as pre-painted steel or coil-coated metal, are composite
materials formed by applying protective and decorative coatings onto cold-rolled steel, galvanize
steel, or galvalume substrates through continuous roll coating and baking processes. These prod
-ucts combine structural strength with superior weather resistance for architectural, appliance,
and transportation applications.
A standard color coated coil consists of multiple functional layers
| Layer | Component | Function | Thickness |
| Substrate | CR (Cold Rolled), GI (Galvanized), or GL (Galvalume) | Structural support | 0.2-1.5mm |
| Conversion Layer | Chromate/phosphate treatment | Adhesion promotion | 0.5-3um |
| Primer | Epoxy/polyester resin | Corrosion protection | 5-10um |
| Topcoat | PE/PVDF/SMP | Color & weather resistance | 15-25um |
Product Classification
By Substrate:
1) Galvanized (GI)
Zinc coating: 60-275g/m²
Ideal for roofing/wall panels
2) Galvalume (GL)
55% Al-Zn alloy coating (AZ150/AZ185)
Superior heat/corrosion resistance
3) Cold Rolled (CR)
Economical option for indoor applications
Coating Type
| Coating | Features | Service Life |
| Polyester (PE) | Cost-effective, color variety | 7-12 years |
| Silicone Modified Polyester (SMP) | Enhanced UV resistance | 10-15 years |
| PVDF (70% PVDF resin) | Extreme durability | 20-30 years |
| High Durability Polyester (HDP) | Balanced performance | 15-20 years |
