| Coating Thickness | Total coating thickness: 20-25μm (primer: 5-8μm; topcoat: 15-17μm); ensures excellent color retention and corrosion resistance |
| Mechanical Properties | Tensile Strength: 18-28 ksi; Elongation: 5-10%; Pencil Hardness: ≥2H; Load-Bearing Capacity: ≥1.2kN/m² (varies by corrugation profile) |
| Coating Performance | Color Fastness: ≥4-5 grade (ISO 105-A02); Adhesion: ≥1 grade (ASTM D 3359-97); Weather Resistance: UV resistance ≥3000 hours QUV aging test (no fading, chalking) |
| Standards Compliance | GB/T 3880, ASTM B 209, EN 485, ISO 2360:2003, AAMA 2603-05 (PE coating standard) |
| Fire Rating | Class A1 (non-combustible), meets global fire safety standards for roofing materials |
| Weight | Approx. 1.89 kg/m² (0.7mm thickness, excluding coating), lightweight and easy to handle |
Key Features & Advantages
Applications
Residential Buildings: Houses, villas, bungalows, and townhouses—adding a modern touch while providing reliable weather protection.
Commercial Buildings: Stores, offices, warehouses, workshops, and shopping malls—combining durability with aesthetic appeal, suitable for large-scale roofing projects.
Industrial Facilities: Factories, workshops, and storage sheds—resistant to industrial pollutants and harsh weather conditions, requiring minimal maintenance.
Public Buildings: Schools, hospitals, community centers, and sports facilities—meeting strict fire safety and durability requirements.
Coastal & Humid Areas: Resistant to salt fog and moisture, making it ideal for coastal homes, marinas, and buildings in humid regions.
Renovation Projects: Perfect for roof replacements, as its lightweight design reduces the need for structural modifications.
Quality Control & Testing
Thickness & Dimension Test: Ensuring 0.7mm thickness (±0.05mm tolerance) and consistent corrugation profile.
Coating Adhesion Test (ASTM D 3359-97): Coating adhesion ≥1 grade, no peeling or chipping.
Color Fastness Test (ISO 105-A02): Color fastness ≥4-5 grade, no fading under UV radiation.
Weather Resistance Test (QUV aging test): ≥3000 hours of UV exposure, no chalking or fading.
Mechanical Performance Test: Tensile strength, elongation, and load-bearing capacity to ensure structural stability.
Fire Rating Test: Class A1 non-combustible, complying with global fire safety standards.
Water Leakage Test: Ensuring the corrugated profile prevents water pooling and leakage.
