Al-Mg-Mn Alloy 3004 Aluminum Siding Coil For Curtain Wall PVDF Coating
3004 series aluminum alloy (Al-Mn-Mg system) undergoes comprehensive surface preparation including cleaning, chemical pretreatment, and high-performance coating application with PVDF fluorocarbon or polyester paints, followed by high-temperature curing. Engineered specifically for demanding architectural applications.
- Curtain walls with superior weather and UV resistance
- Lightweight, corrosion-resistant roofing systems
- Architectural decoration with versatile colors and finishes
3004 is an Al-Mn-Mg series alloy typically supplied in H34/H44 tempers that delivers exceptional performance when color-coated:
- Tensile strength: 180-240 MPa (H34 temper reaches ≥240 MPa)
- Elongation: ≥8% (H34) - excellent for stamping and forming operations
Manganese and magnesium elements enhance atmospheric and rain corrosion resistance for long-term durability.
Excellent bendability and deep-drawing capability for complex facade shapes and architectural designs.
Available in coil and sheet formats with production capability for ultra-wide 1800mm coils at maximum width.
- Lightweight: Density: 2.7g/cm³ (65% lighter than steel), significantly reducing structural loads
- Aesthetic Flexibility: Custom PVDF colors including metallic and woodgrain effects with superior UV resistance (ΔE<3 after 15 years)
- Weather Resistance: Stable performance across extreme temperatures from -40℃ to 80℃ with no cracking or deformation
- Cost Efficiency: Lower lifecycle cost compared to stainless steel or zinc with minimal maintenance requirements
- Skyscrapers: Shanghai World Financial Center (decorative elements)
- Airports: Beijing Daxing Airport (curved sunshades)
- Commercial Complexes: Parametric facade systems
