Color Coated Galvanized Steel Coil PPGI
deskribapen laburra:
PPGI (Pre-Painted Galvanized Iron) Steel Coils combine hot-dip or electro-galvanized bases with UV-resistant polymer coatings, offering 5–15-year lifespans in harsh environments. Designed for roofing, appliances, and automotive parts, PPGI achieves ASTM B117 500h salt spray resistance and 85% solar reflectance. Available in RAL 9000–RAL 9023 hues, these coils feature PE/SMP/HDP/PVDF coatings (10–30µm) with gloss levels up to 95 GU for architectural and industrial use.

Technical Specifications
1. Base Material & Dimensions
| Parameter | Hot-Dip PPGI | Electro-Galvanized PPGI |
|---|---|---|
| Zinc Coating | 275 g/m² (Z275) | 20–90 g/m² (ZE20–ZE90) |
| Thickness | 0.13–0.8 mm (±0.02mm tolerance) | 0.13–0.6 mm (±0.02mm tolerance) |
| Width | 600–1,250 mm (slit-to-size) | 600–1,250 mm |
| Coil Weight | 3–12 tons (ID: 508/610 mm) | 2–8 tons |
2. Coating System
| Layer | Coating Type | Thickness | Key Performance |
|---|---|---|---|
| Topcoat | PVDF/HDP/SMP/PE | 15–30 µm | 15+ years color retention (ISO 4892) |
| Primer | Epoxy/Polyester | 5–15 µm | Adhesion: Class 0 (ISO 2409 cross-cut) |
| Backing Coat | Acrylic/Polyurethane | 5–10 µm | Anti-fingerprint, scratch resistance |
Surface Treatments & Performance
1. Laminated Film (30–50µm)
- Features: Fire resistance (Class A ASTM E84), anti-graffiti, fingerprint-proof.
- Applications: High-traffic areas (elevators, subway panels).
2. Embossed Finish
- Patterns: Stucco, rhombus, wood grain (customizable).
- Benefits: 3D texture hides scratches, improves slip resistance (Rz ≥8µm).
3. Coating Comparison
| Type | UV Resistance | Cost | Best For |
|---|---|---|---|
| PVDF | 20+ years | High | Coastal roofs, façades |
| HDP | 15 years | Moderate | Solar farms, HVAC ducts |
| SMP | 10 years | Low | Indoor partitions, furniture |
| PE | 5–7 years | Budget | Temporary structures, packaging |
Performance Advantages
- Corrosion Resistance: Z275 hot-dip base outperforms electro-galvanized by 3x in humidity.
- Formability: 0.4T bend radius (0.3mm thickness) for roll-forming/press-braking.
- Thermal Efficiency: Reflective coatings reduce rooftop temps by 10–15°C (ASHRAE 90.1).
- Weight Savings: 30% lighter than aluminum panels (2.7 g/cm³ density).
- Cost-Effective: 40% cheaper than PPGL with comparable durability in mild climates.
Industry Applications
| Sector | Use Case | Recommended Coating |
|---|---|---|
| Construction | Warehouse roofs, cladding | PVDF (RAL 9006) |
| Automotive | Truck trailer interiors | SMP (RAL 7035) |
| Appliances | Washing machine panels | HDP (RAL 1015) |
| Furniture | Office cabinets, lockers | PE (RAL 5021) |
Certifications & Standards
- Quality: ISO 9001, ASTM A653 (Galvanized)
- Safety: EN 13501-1 (Fire Class B-s1, d0)
- Sustainability: 25% recycled content, RoHS-compliant coatings
