Surface Finishing Options for Chalco Aluminum Round Tubes

Chalco offers a wide range of surface finishing processes tailored for aluminum round tubes, designed to enhance corrosion resistance, wear durability, and aesthetic appeal. From anodizing to powder coating, brushed finishes, and electrophoretic coating, each treatment is engineered to ensure exceptional performance and long-term stability in demanding environments.

• Anodizing

  An electrochemical process that forms a dense oxide layer (10–25μm) on the tube surface. Anodized aluminum round tubes offer excellent corrosion and wear resistance, with color options such as silver, black, and gold. Ideal for outdoor structures, marine applications, and humid environments.

• Powder Coating

  A static spray process that bonds powder coating to the surface, then cures it under high heat. Offers vibrant colors, enhanced UV/weather resistance, and superior impact durability. Common in furniture, signage, and industrial components.

• Brushed Finish

  A mechanical sanding process that creates fine, uniform textures for enhanced metallic appearance and scratch resistance. Used in premium home décor, consumer electronics, and decorative applications.

• Polishing

  Mechanically polishes the surface to achieve mirror-like or high-gloss effects, suitable for automotive trim, display pieces, and high-end electronic products, boosting visual appeal and surface smoothness.

• Electrophoretic Coating

  Applies a uniform coating using electrophoresis technology to enhance salt spray resistance and corrosion protection. Offers a smooth, strong, and color-stable surface, often used for automotive parts and architectural profiles.

• Sandblasting

  Uses high-speed abrasives to create a matte, textured surface. Improves paint/coating adhesion and is commonly used in industrial equipment and structural components as a pre-treatment step.
