1100 Color Coated Aluminum Coil

Overview of 1100 Color Coated Aluminum Coil

The 1100 color coated aluminum coil is a high-purity aluminum product made from 1100 alloy as the base material. It is processed through multiple precise steps including degreasing, chemical conversion, coating, and baking, to form a decorative and protective color coating on the surface.
The coating can be applied by roller coating or spray coating production lines, using different types of paints such as PE, PVDF, HDPE, FEVE, or custom coatings.

With an aluminum content of 99.0% or higher, 1100 aluminum has excellent corrosion resistance, formability, and surface processing performance.
After applying the color coating, the coil not only gains an attractive appearance but also demonstrates outstanding weather resistance, UV aging resistance, and anti-corrosion properties.
It is widely used in architectural decoration, home appliance panels, ceilings, curtain walls, roofing sheets, and transportation applications.

Features of 1100 Color Coated Aluminum Coil

1. Lightweight and Highly Ductile

Low material density and strong ductility allow easy stamping, bending, drawing, and laminating, making it suitable for various shapes and structures.

2. Surface Flatness

Smooth surface without composite high-temperature impressions; no residual stress after shearing and no deformation.

3. Aesthetic Appeal

Available in wood grain, stone grain, and other realistic textures that simulate natural materials.
Patterns can be customized, offering customers a wide range of design options.

4.. Weather resistance

The painted patterns, applied by joint coating and high-temperature baking, maintain high gloss, have good color stability, and minimal color difference. Polyester paint has a 10-year warranty, and fluorocarbon paint has a warranty of over 20 years.

5. Mechanical Strength

Produced using premium aluminum, adhesives, and composite techniques, ensuring sufficient bending and flexural strength to withstand seasonal temperature, wind pressure, and humidity changes without deformation or expansion.

6. Environmental Protection

Resistant to salt, alkali, and acid rain corrosion; non-toxic and free from bacteria growth.
Does not release harmful gases or cause rusting of structures.
Meets national fire resistance standard B1 level.

Production Process of 1100 Color Coated Aluminum Coil

The production of color coated aluminum coils requires high precision and strict quality control, involving the following steps:

Uncoiling → Degreasing and Cleaning → Roller Coating → Drying → Inspection → Recoiling → Packaging

Depending on the coating system, single-coat, double-coat, or triple-coat baking processes can be applied.

During pretreatment, continuous spraying and cleaning enhance corrosion resistance and coating adhesion.
A conversion film is chemically formed on the aluminum surface for improved paint bonding.

The coating process includes two stages - primer coating and top coating.
After primer application, the aluminum coil is dried, and the surface is roller-coated with the top paint layer.
During curing, the coil passes through an oven with controlled temperature (200-300°C) to ensure complete polymerization and elimination of volatile compounds.
