1000 3000 Series Aluminum Alloy Coil Used For Roofing Panel
Aluminum alloy coils used as corrugated roofing sheets are a common construction application,
offering advantages such as lightweight properties, corrosion resistance, easy processing, and
aesthetic appeal.
Commonly Used Aluminum Alloy Series
1) 3000 Series Aluminum Alloys (Al-Mn Alloys)
Common Grades: 3003, 3004, 3105
Key Features:
• Excellent corrosion resistance (ideal for outdoor exposure).
• Moderate strength with superior formability, making them easy to roll into corrugated profiles.
• Cost-effective, offering a good balance of performance and price.
2) 5000 Series Aluminum Alloys (Al-Mg Alloys)
Common Grades: 5052, 5083, 5754
Key Features:
• Higher magnesium content (2.5–5%), providing significantly greater strength than 3000 series.
• Outstanding resistance to saltwater and industrial atmospheres, suitable for coastal or high-
humidity areas.
• Good weldability, ideal for large roofing systems requiring seams.
3) 1000 Series Aluminum Alloys (Pure Aluminum)
Common Grades: 1050, 1060, 1100
Key Features:
• High purity (>99% aluminum), offering exceptional corrosion resistance but the lowest strength.
• Excellent ductility, suitable for deep drawing or complex corrugated shapes.
Standard Thickness Selection
| Application | Thickness (mm) | Technical Basis |
| Lightweight Roofing | 0.6~1.0 | Slope >5°, low wind pressure (≤0.3kPa) |
| Standard Industrial Roof | 1.0~1.5 | Wind load ≥1.0kPa (EN 1991-1-4) |
| High Wind/Snow Regions | 1.5~2.5 | Tear-resistant design (coastal/alpine) |
| Solar Roof Base | 1.2~2.0 | Supports PV modules (≥30kg/m²) |
Key Benefits
✅ Lightweight: Density 2.7g/cm³ (1/3 of steel), reduces structural load by 30%+
✅ Weather Resistance: PVDF coating (≥25μm) retains color for 25 years
Anodized layer (10-20μm) resists UV degradation
✅ Easy Installation: Standing seam/concealed clip systems (IPX7 waterproof)
Single panels up to 30m long (minimizes seams)
✅ Eco-Friendly: 100% recyclable, 95% lower energy for recycled aluminum
Solar reflectance ≥80% (cuts cooling costs)
Innovative Applications
♦ Solar-Integrated Roofs: 2.0mm 5052 panels with PV (load ≥60kg/m²)
♦ Ventilated Roofs: 0.8mm perforated panels (15-30% open area) + waterproof membrane
♦ Self-Cleaning Nano-Coating: Contact angle >150° (rain-assisted dirt removal)
Company Advantages
We use the Wolrd Advanced Equipments for your Aluminium Alloy Material
• All the melting and holding furnaces are supplied by GAUTSCHI (Switzerland) Company.
they improve the quality of Aluminum alloy slab which can guarantee Aluminium alloy
products with high-performance.
