Electrophoretic Coating (E-Coating)
Electrophoretic coating, also known as electrophoresis or e-coating, is a premium surface treatment often combined with anodizing to achieve superior performance for aluminum profiles. The process starts with anodizing, where a transparent oxide film forms on the surface of the aluminum, offering a protective base layer that improves corrosion resistance and adhesion. After anodizing, the profiles are immersed in an electrically charged water-based solution during the e-coating process. This deposits a uniform paint layer onto the oxide film, combining the protective benefits of anodizing with the durability and aesthetics of electrophoretic coating. The result is dual-layer protection, delivering enhanced strength, durability, and aesthetic appeal.

| Applications | Architecture, high-end decoration, industrial components. | Suitable for structural parts with moderate performance requirements. |
Powder coating is an advanced surface finishing process for aluminum profiles that provides excellent durability, corrosion resistance, and vibrant aesthetics. It involves applying an electrostatically charged powder to the aluminum surface, which is then cured under high heat, creating a protective, uniform, and long-lasting coating. This finish is resistant to fading, chipping, and scratching, while offering a broad range of textures, gloss levels, and custom colors. At HTS-ALU, we can produce powder-coated finishes based on RAL color charts or Pantone color matching, ensuring we meet diverse design needs and specific customer preferences.
At HTS-ALU, we operate two vertical and two horizontal powder coating lines, enabling us to handle a wide variety of profile sizes and designs. Vertical lines are ideal for efficiently coating large or long aluminum profiles used in construction and industry, while horizontal lines allow for precision coating of smaller, intricate components perfect for decorative and detailed applications. This versatility enables us to deliver high-quality solutions for many industries, such as architecture, automotive, and furniture manufacturing.
