| Surface Treatment | Feature |
| Mill finish | Raw material for secondery surface treatment. Natural aluminum material, without any coating. Cheaper cost. The aluminum profile itself will forms a weak oxide film in the air-- Have weak corrosion resistance. Mill finish normal suitable for industry product like heat sink etc. |
| Powder coating | Electrostatic spraying, the powder can cover profile, smooth surface, durable. The film thickness normal have 60-120μm. It can protect the surface from corrosion. Available in all kinds of color. Suitable for outdoor usage. Powder Coating Aluminum Door Profile |
| Anodizing | Oxidation film thickness normal is 8-12μm, durable, corrosion-resistant, less machinery line. Avaliavle in planty of color, such as: Sliver, champange, bronze, black, steel, golden etc. Customized color also avaliable. |
| Wooden grain | Transform texture like real wood on profile surface, without mechanical lines, corrosion-resistant, durable. Avaliable in all kins of wooden pattern, 3D/4D wooden grain, powder coating wooden and electrophoresis wooden grain. |
| Electrophoresis | There is a transparent electrohporesis film on surface. 20 years quality assurance, with smooth surface, highly-wear resistance, corrosion-resistant, durable. Avaliavle in planty of color, such as: Sliver, champange, bronze, black, steel, golden etc. Customized color also avaliable. Suitable for outdoor usage. |
| PVDF coating | Fluorocarbon spraying, PVDF paint does same as car painting. 20 years quality assurance, with smooth surface, highly-wear resistance, corrosion-resistant, durable. Avaliavle in all kinds of color. Customized color also avaliable. Suitable for outdoor usage. |
| Sandblasting | Pre-treatment for anodizing. Use sand impact on profile surface, it can cover machinery line. Suitable for decoration. Avaliable in all kinds of sand such as quartz sand, steel sand etc. |
| Brushing | Pre-treatment for anodizing. Even brush on profile surface, it can cover machinery line. Suitable for decoration. |
| Polishing | Pre-treatment for anodizing. By buffing and chemical anodizing to form the surface like mirror. Suitable for decoration, use for indoor product. |
