If an additional surface protection or enhanced finish, such as painting, powder coating or anodizing, is desired, FINE can assist. Our knowledge of alloys, their properties, and their end uses enables us to help you choose the correct finish for your project.
Aluminum has a naturally occurring oxide film that protects it from corrosion. This oxide film is sufficient for many applications. However, in extreme environments, extra protection may be required.
Depending on the look you are trying to achieve, you will need to select the appropriate finish. Especially for end-use aluminum products, finishing means added value while on market.
The process of aluminum anodizing adds a layer of oxidation to aluminum extrusion products. Unlike iron or carbon steel where oxidation creates a layer of corrosion or rust, the anodizing process actually enhances the properties of aluminum.
Powder coating is completely dry finishing process, yielding color-rich, long-lasting surfaces that withstand any weather conditions, and resist scratches and color fading. Unlike liquid paints, the powder coating process does not involve the use of any solvents, making it an almost pollution free application.
Electrophoretic painting is to cover acrylic resin paint evenly on the aluminum profiles, sealed without porosity. This immersion wet paint finishing process uses electrical current to attract the painting onto the aluminum surface.
Polyesters, acrylics, siliconized polyesters, and fluoropolymers are available in a virtually unlimited array of colors.
A wide variety of mechanical methods such as sanding, polishing, grinding, buffing, blasting can be used to obtain a wide variety of textures.
Etching yields a frosted, matte surface appearance, while bright-dipping produces a specular (mirror-like) finish.
