Industrial aluminum profile is a die extrusion cross-section alloy profile. The extruded profile is the substrate, also known as the material. The color is single, and the corrosion resistance and wear resistance are poor. In order to increase the physical and chemical properties of profiles, surface aesthetics. Extruded profiles often require surface treatment. There are several common surface treatment methods.

1, chromium: This way is to form a layer of chemical conversion film on the surface of the profile, the adsorption of the film is better, can be used for a variety of coating bottom, the advantage is that the color is rich and optional. Suitable for aluminum and aluminum alloy, aluminum magnesium alloy.

2, anodizing: this is a common surface treatment method for industrial aluminum profiles. The principle is to form an oxide film on the surface of the profile, the advantage is that it can increase the corrosion resistance and wear resistance of the profile, and has an insulation effect, which is suitable for a variety of industry production fields and can play an anti-static role.

3, electrophoresis: the effect is similar to spraying, is to form a layer of organic coating on the surface, rich in color, good decorative selection, good durability.

4, electroplating: there are many ways, common nickel plating, silver plating, gold plating, zinc plating, copper plating, chromium plating, etc. The advantage is a variety of options, can be selected according to their own needs, can increase the physical and chemical properties of the product.

5, powder spraying: common ways are dip coating, spraying, brush coating and so on. The principle is to form an organic coating on the surface of the profile, and the advantage is that the color is rich and multi-choice, and the decoration is good, which can also increase the corrosion resistance and maintain the durability of the color.
