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.

• German SMS Group fully automated coating lines with ±0.01mm thickness precision
• Line Speed: 120m/min (20% faster than industry average)
• MES system enables real-time production monitoring with ≥99.3% product qualification rate
• Multi-spectral imaging detects micro-defects as small as 0.02mm² with 99.8% recognition accuracy
