Item | Parameters/Specifications | Notes |
---|---|---|
Base Material | Galvanized Steel (GI), Aluminum-Zinc Coated Steel (GL), Al-Mg-Mn Alloy | - GL (55% Al-Zn) offers superior corrosion resistance for humid/coastal areas - GI is cost-effective for moderate climates |
Thickness | 0.3mm-0.8mm (standard export range) Customizable up to 1.5mm |
Thickness determines load capacity; recommend based on application. |
Coating Weight | - Galvanized (Z): 60-275g/m² - Al-Zinc (AZ): 100-200g/m² |
Higher coating weight = better corrosion resistance (e.g., AZ150 = 150g/m² Al-Zn layer). |
Coating Type | - Polyester (PE) - Silicon Modified Polyester (SMP) - Polyvinylidene Fluoride (PVDF) |
- PE: Budget-friendly, 5-8 years durability - SMP: UV-resistant, 10-15 years - PVDF: Extreme weather/chemical resistance, 20-30 years fade-free |
Coating Thickness | Front: 20-25μm Back: 5-10μm (dual-side coating) |
Dual-side coating extends service life. |
Color Standard | RAL, Pantone color customization Common colors: White (RAL9016), Ocean Blue (RAL5010), Brick Red (RAL3009) |
Special colors require higher MOQ. |
Tensile Strength | 280-550MPa | High-strength grades (≥380MPa) for load-bearing structures. |
Salt Spray Test | - GI base: 500-1000 hours - GL base: 1000+ hours |
Test standard: ASTM B117 |
Fire Rating | Class A (Non-combustible) | Compliant with EN13501-1/GB8624. |
Temperature Range | -50°C to +120°C | Stable performance in extreme climates. |
Panel Dimensions | Effective width: 600-1200mm Length: Custom (typically ≤12m) |
Custom profiles available (corrugated, concealed-clip panels, etc.). |
Weight | 5-12kg/m² | Lightweight design reduces transport/installation costs. |
Minimum Roof Slope | 3° | Suitable for flat or low-slope roofs. |
International Standards | - ASTM A755 (USA) - EN10169 (EU) - JIS G3312 (Japan) |
Third-party test reports (e.g., SGS) available. |
Eco-Certifications | RoHS, LEED | Meets green building requirements. |
Typical Applications | Industrial plants, warehouses, commercial buildings, agricultural greenhouses, temporary structures | Compatible with insulated sandwich panels (rock wool, polyurethane). |
