Surface Finish

Anodizing

Forms a protective oxide layer for durability and color options.

Advantages: Excellent corrosion resistance, hard surface, and long-lasting color.

Brushed

Creates fine, linear textures for a modern metallic look.
Advantages: Smooth surface, hides scratches, and enhances visual appeal.

Electrophoresis Coating

Creates a smooth, glossy, and uniform protective layer through an electrochemical process.
Advantages: Excellent corrosion resistance, consistent color, and strong adhesion for long-lasting finish.

Polished Finish

Produces a mirror-like reflective surface.
Advantages: High gloss, premium appearance, and easy to clean.

Sandblasted

Uses high-pressure abrasive blasting for a matte, uniform texture.
Advantages: Non-glare surface, better coating adhesion, and clean industrial style.

Painting Finish

Applies liquid paint for color, protection, and decorative effect.
Advantages: Wide color selection, smooth surface, and enhanced corrosion resistance at low cost.

Heat Transfer Printing

Applies decorative patterns such as wood grain or marble effect onto aluminum surfaces using heat and pressure.
Advantages: Realistic texture, high weather resistance, and durable decorative finish.
