Anodizing is a final treatment process that gives some metals a stronger finish featuring high hardness and excellent corrosion resistance.

Anodizing aims at protecting the metal surface by coating it with a layer of insoluble oxide to protect against corrosion and yield a clean surface finish that functions as a basis for any subsequent coating required to achieve certain electrical and mechanical properties.

Aluminum anodizing process starts by preparing the surface mechanically and chemically, followed by using an acid solution and electrical charge in a controlled temperature ambience to produce a homogeneous and dense layer on the piece. Next, aluminum oxide penetrates the aluminum surface and a layer of aluminum oxide starts to build up.

Also, oxidization layer can be dyed or electro-colored at the end of the process, prior to sealing, to yield a decorative and colorful finish.

A polished shining surface may be obtained mechanically by running high-speed rotating brushes or by chemical brightening.

Our aluminum anodizing line is equipped to anodize aluminum profiles with lengths up to 6500 mm.

Available color and shades are champagne, bronze and black.
