How to choose surface treatment for aluminum profiles? Comparison of applicable scenarios for anodizing, powder coating, and electrophoresis
2026,09,17
Introduction: Both are industrial aluminum profiles, and the surface treatment process directly determines their service life, appearance, anti-corrosion ability, and procurement cost. Overseas customers often confuse anodizing, powder coating, and electrophoresis processes. Choosing the wrong process can lead to rapid aging during outdoor use or dust pollution in clean workshops.
Anodizing is the most common solution for industrial aluminum profiles, which generates a dense oxide film on the surface of aluminum. It is wear-resistant, weakly conductive, suitable for automation racks, equipment frames, and commonly used in clean workshops; The disadvantage is limited color options.
Powder spraying, with a higher coating thickness, strong UV resistance, and rich colors, is commonly used for outdoor fences, photovoltaic brackets, and building aluminum profiles; However, the coating is prone to powdering upon impact and is not suitable for industrial frames that require frequent disassembly and friction.
Electrophoretic treatment results in a smooth and delicate surface with excellent anti-corrosion performance. It is commonly used for building doors and windows, but the cost is relatively high and it is less commonly used in the industrial equipment field.
Key selection points: Prioritize anodizing indoor equipment racks; Prioritize powder coating for long-term outdoor environments; Avoid coating processes that are prone to powder loss in clean and dust-free environments.
