Al-Mg-Mn Alloy 3004 Aluminium Coated Sheet Building Curtain Wall
3004 series alloy (Al-Mn-Mg system) undergoes comprehensive surface cleaning, chemical pretreatment, and coating application with high-performance PVDF fluorocarbon or polyester paints, followed by high-temperature curing for superior performance.
We are a professional color coated aluminum material manufacturer with 3 production lines for coil and 2 lines for sheet, supporting maximum widths up to 2700mm.
- Clear internal management and standardized processes ensure smooth, efficient production
- Main products include color coated aluminum coil, wood grain coated aluminum coil, stone texture coated aluminum coil, Al-Mn-Mg roof aluminum coil, and mirror finish coated aluminum coil
- Additional capabilities: curtain wall aluminum veneer, aluminum honeycomb panel, heat transfer printed aluminum coil
- Raw material testing for bending and hardness properties to ensure alloy temper meets requirements
- Online inspection systems monitor key parameters including coating thickness, uniformity, and adhesion
- Pre-delivery sample testing including grid testing, impact testing, and bending testing
- Chemical testing for special products and comprehensive MTC documentation for every batch
- Curtain walls
- Roofing systems
- Architectural decoration
Tensile strength: 180-240 MPa (H34 temper reaches ≥240 MPa)
Elongation: ≥8% (H34), excellent for stamping and forming operations
- Enhanced corrosion resistance from Mn and Mg elements for atmospheric/rain conditions
- Excellent bendability and deep-drawing capability for complex facade shapes
| Temper | Characteristics | Typical Applications |
|---|---|---|
| H34 | Half-hard, high strength, good formability | Curtain wall panels, 3D cladding |
| H44 | Enhanced corrosion resistance, moderate strength | Coastal/high-humidity areas |
| O (Annealed) | Soft, superior deep-drawing capability | Special curved designs (less common) |
Density: 2.7g/cm³ (65% lighter than steel), significantly reducing structural loads
Custom PVDF colors including metallic and woodgrain effects with superior UV resistance (ΔE<3 after 15 years)
