Al-Mg-Mn Alloy 3004 Aluminium Coated Sheet For Building Curtain Wall

3004 series alloy (Al-Mn-Mg system) that undergoes surface cleaning, chemical pretreatment,

and coating application (typically with high-performance PVDF fluorocarbon or polyester paints)

followed by high-temperature curing.

At the same time, we can produce curtain wall aluminum veneer, aluminum honeycomb panel,

heat transfer printed aluminum coil.

Inspection and Testing Measures for Color Coated Aluminum Coil

1) We test the bending and hardness property for every batch raw material, make sure the Alloy

Temper can meet customer’s requirement.

2) During the production process, we use online inspection systems to monitor key parameters,

such as coating thickness, uniformity, adhesion.

3) Before delivery, we will select samples to test, including grid testing, impact testing, and bending

testing. For some special products, we will carry out some chemical testing.

4) We have MTC for every batch product, convenient for tracking and confirmation. Test records

are kept by our laboratory staffs.

Primarily used for:

• Curtain walls

• Roofing systems

• Architectural decoration

Key Characteristics of 3004 Aluminum Coil

Mechanical Properties

Tensile strength: 180-240 MPa (H34 temper reaches ≥240 MPa)

Elongation: ≥8% (H34), excellent for stamping and forming

Corrosion Resistance

Mn and Mg elements enhance atmospheric/rain corrosion resistance

Formability

Excellent bendability and deep-drawing capability for complex facade shapes

Common Tempers

Performance Advantages for Curtain Walls

♦ Lightweight

Density: 2.7g/cm³ (65% lighter than steel), reducing structural loads

♦ Aesthetic Flexibility

Custom PVDF colors (metallic, woodgrain effects) with UV resistance (ΔE<3 after 15 years)
