High Wind-load Resistance 3003 3004 Aluminum Alloy Coil for Curtain
Wall
Aluminum material for the curtain wall, the natural oxide layer
combined with PVDF/anodized
coatings resists UV/salt corrosion, delivering 25+ years service
life with minimal maintenance.

Our Workshop
All the melting and holding furnaces are supplied by GAUTSCHI (Switzerland)
1+1+4 hot rolling mills and 1+5 hot rolling mills from SMS Group (Germany).
6 sets of cold rolling mills from SMS Group (Germany) ......
1) We introduced a wide range of world-class equipments to ensure
product quality.
2) We specialize in high-quality aluminum alloy coils, with key
grades such as 1050, 1060,
1100, 3003, 3004, 3104, 5052 and 6061.
3) We follow clear internal management and standardized processes
to keep our production
smooth, efficient, and well-organized.
Automatic Aluminum Coil Wrapping Machine
1) Less manual work, faster and easier packaging.
2) Accurate control for neat, consistent wrapping every time.
3) Tightly wrapped coils stay secure and are easy to transport.
All Automatic Three-dimensional Elevated Warehouse
♦ Smart Storage: it can automatically handles high-temperature coils from hot and
cold rolling,
monitoring their temperature at the same time.
♦ Automated Transport: automated coil transport cars smoothly plan their routes based on
production needs.
♦ Flexible Handling: all the coils are efficiently and flexibly delivered to the next
production stage.
Alloy Ingot Storage Area
This area is used to store different types of alloy ingots.
Materials are neatly stacked for easy tracing and handling, ready for use before rolling.
Ocean Shipping
1) We use cushioning materials between the coil and wall, and tighten
everything with specialized
lashing straps.
2) we place non-slip wooden blocks under each coil to prevent any
movement during the shipping.
3) It has the waterproof layer inside the package, we also put many
desiccants in the container,
to protect the cargo from moisture
Alloy Material Selection Guide
| Alloy | Temper | Tensile Strength | Key Feature | Typical Use |
| 3003 | H14/H24 | 145-185 MPa | Cost-effective | Basic cladding |
| 3004 | H34 | 200-240 MPa | High wind-load resistance | Coastal areas |
| 5052 | H32 | 230-280 MPa | Excellent corrosion resistance | Industrial zones |
Key Advantages
✅ Lightweight & High Strength
Density: 2.7g/cm³ (1/3 of steel), reducing structural load
5052-H32: Tensile strength ≥230MPa; 6061-T6: Up to 310MPa
✅ Superior Weather Resistance
Natural oxide layer resists UV; Anodizing triples durability
5,000-hour salt spray test (GB/T 10125 compliant)
✅ Design Flexibility
Roll-forming, bending, stamping (min. bend radius = thickness)
Supports parametric curved designs (e.g., double-curvature walls)
✅ Diverse Surface Finishes
| Finish | Features | Applications |
| PVDF Coating | 20-year color retention | Landmarks (e.g., Shanghai Tower) |
| Anodizing | Metallic finish, hardness ≥300HV | Premium office buildings |
| Wood Grain | Natural texture, -40~80℃ range | Cultural/retail projects |
✅ Energy Efficiency
Solar reflectance ≥80% (reduces cooling costs)
100% recyclable; recycled aluminum uses 95% less energy
