Excellent Decorative Property Brushed Surface Color Coated Aluminum Coil

A pre-finished aluminum coil featuring a mechanically or chemically brushed surface with

uniform linear or random patterns, combined with durable color coatings for enhanced

aesthetics and functionality.

Key Features

a) Surface Finishes

Linear brushing (unidirectional grain)

Random brushing (non-directional pattern)

b) Coating Systems

Polyester (PE) for indoor applications

PVDF for superior outdoor durability

Performance Advantages

• Excellent Decorative Properties

Brushed Texture: A fine metallic grain pattern achieved through mechanical or chemical

brushing, enhancing visual appeal for modern, minimalist, or industrial designs.

Color Coating: PVDF (polyvinylidene fluoride) or PE (polyester) coatings offer rich colors

(e.g., wood grain, stone patterns, solid colors) and UV resistance, preventing fading over time.

• Lightweight & High Strength

Low Density (~2.7 g/cm³): ~1/3 lighter than steel, reducing structural load and installation/transport costs.

High Strength: Alloying (e.g., with magnesium/silicon) and work hardening achieve tensile strengths

of 150–300 MPa, suitable for structural parts.

• Corrosion Resistance

Natural Oxide Layer: Aluminum oxide (Al₂O₃) resists atmospheric and rainwater corrosion.

Protective Coating: PVDF coatings withstand acids, alkalis, and UV rays, ideal for coastal/industrial

areas (20+ years lifespan).

• Easy Processability

Flexibility: Easily cut, stamped, or bent (e.g., for AC housings, curtain walls).

Welding/Riveting: Certain grades (e.g., 3003, 5052) are weldable, compatible with multiple joining methods.

• Eco-Friendliness & Sustainability

Recyclability: Aluminum is >90% recyclable, with recycled production using just 5% of original energy.

Non-Toxic Coatings: PVDF coatings are heavy-metal-free, compliant with RoHS/REACH standards.

Typical Applications

♦ Architectural cladding (elevator interiors, decorative trims)

♦ High-end appliance panels (refrigerators, ovens)

♦ Consumer electronics (laptop casings, audio equipment)

♦ Interior design elements (cabinet surfaces, space dividers)
