Surface treatment directly determines the corrosion resistance, wear resistance, appearance texture, and service life of aluminum profiles. Different processes are suitable for different scenarios. Anodizing: A dense oxide film of 10–20μm is formed, which is wear-resistant, corrosion-resistant, has a fine texture, and strong metallic luster. It is suitable for industrial frames, high-end decoration, and outdoor structures.
Powder coating: Electrostatic spraying of resin powder, featuring rich colors, strong adhesion, good weather resistance, and UV resistance, suitable for doors and windows, curtain walls, outdoor furniture, and offering high cost performance.
Electrophoretic coating: A transparent or colored paint film is formed on the oxide film, resulting in a uniform and fine surface, resistance to stains and weathering, and high glossiness. It is suitable for high-end doors and windows, sunrooms, and interior decoration.
Fluorocarbon coating: Using fluorocarbon resin, it boasts excellent weather resistance, anti-fading, and corrosion resistance, making it suitable for super high-rise curtain walls, coastal buildings, and harsh environments. Its lifespan can reach up to 50 years.
Wood grain transfer printing: It simulates the texture of real wood grain, with a realistic texture and resistance to scratching and wear, suitable for indoor decoration, antique doors and windows, and garden landscapes.
Selection suggestions: For industrial use, choose anodizing; for doors, windows, and exterior walls, choose powder coating or electrophoresis; for high-end applications or coastal areas, choose fluorocarbon; for interior decoration, choose wood grain.
