Color aluminum coil

Pre-coated aluminum coils (also called pre-coated aluminum sheets or pre-painted aluminum coils) are aluminum products made by cleaning and chemically treating the surface of aluminum coils, then coating them with one or more layers of organic coatings (such as polyester PE, PVDF, etc.) and baking and curing them. In short, they are "aluminum coil materials that have already been painted with color paint" and can be directly processed into various finished products.

Main features of color-coated aluminum coils

• Rich colors and aesthetically pleasing;Corrosion and oxidation resistant;
• Good weather resistance (especially PVDF);
• Easy to process, stampable, and bendable;
• Smooth surface and easy to clean.

Common Color-Coated Aluminum Coil Materials

• 1000 Series (Pure Aluminum Series)

Representatives: 1050, 1060, 1100 High Aluminum Content (≥99%)

Characteristics

1. Soft, good ductility
2. Good corrosion resistance
3. Low strength

Applications: Decorative panels, insulation materials, food packaging

In short: Softest, purest, easiest to process

• 3000 Series (Aluminum-Manganese Alloy) Most Commonly Used

Representatives: 3003, 3004 Added Manganese

Characteristics:

1. Higher strength than pure aluminum
2. Good rust resistance
3. Moderate cost

Applications: Color-coated aluminum coil substrate
Building roofing Insulation, ceilings

In short: Best overall performance, most commonly used in construction

• 5000 Series (Aluminum-Magnesium Alloy)

Representatives: 5052, 5005, 5083 Added Magnesium

Characteristics:

1. High strength
   Strong resistance to seawater corrosion
   More durable
2. Applications: Curtain wall systems
   Ships
3. High-end building facades

In short: High strength + Highly corrosion resistant (for high-end products)

Color-coated Aluminum Coil vs. Color-coated Steel Coil

Rich colors, customizable according to RAL color charts.

Customized Cases

• We can apply a PVC protective film to the surface according to your needs. This is called coated color steel sheet, which protects the delicate paint surface of the color steel sheet during processing.

  

• We can emboss patterns onto the smooth surface of galvanized color steel sheets according to your needs. This is called embossed color steel sheet, and it comes in diamond and orange peel shapes. We can also customize it to your specific shape.

Quality Inspection

• We first conduct a visual inspection to ensure the galvanized color steel coils are free of defects, facilitating subsequent processing and aesthetic use.
• Coating Performance Testing: We use a magnetic thickness gauge or coating thickness gauge to test the paint film thickness, ensuring it meets the customer's required thickness. JXL STEEL can produce paint films with a thickness of 25 microns on both the front and back sides. After testing, we sequentially conduct adhesion, bending performance, hardness, and impact resistance tests to ensure the paint does not crack or peel during customer use, and the product is fully qualified.
• Corrosion Resistance Testing: We will conduct salt spray tests to ensure that the color remains vibrant even in harsh operating environments.
• Substrate Mechanical Property Testing

  Project	Method	Common requirements
  Yield strength	tensile test	190~350 MPa
  Tensive strength	tensile test	270~450 MPa
  Elongation	tensile test	≥20%
  Bending performance	bending test	Bending diameter as specified by thickness
  Stamping performance	stamping test	No cracks
