The color painting protects the aluminum profile from the harmful environment and makes an attractive finish of the end product. The layer thickness varies from 5 to 30 microns.
What is anodizing used for?
Anodizing creates a protective and decorative layer on the profile surface. It is practicable when the appearance, service life, corrosion- and wear-resistance are the key. Also, it provides consistent coverage.
The process of anodic oxidation in sulfuric acid solutions has proven to be a reliable way to protect the aluminum profile from damaging corrosion. This process is also called profile anodizing. The oxide layer produced by an electrolytic method has a density of 200-2000 times greater than natural oxide films. Compared to the other coating methods (i.e., varnishing, painting, polymer film coating), anodizing eliminates the problems of delamination and underfilm corrosion.
Anodizing provides excellent properties such as wear-, abrasion and erosion resistance, as well as electrical and thermal insulation. The coating is very resistant to corrosion in aggressive environments.
You can purchase aluminum anodizing only
or entrust us with a full-cycle aluminum profile production.
We offer 6 colors, with a coating thickness from 5 to 30 microns. To remove traces of extrusion, the profile is bead blasted and etched, then anodized.
