This chemical oxidation process is based on the electrolysis that takes place on the surface of the profiles. A layer of aluminum oxide is formed by immersing the aluminum profiles in a sulfuric acid bath, to which an electric current between the aluminum (the anode) and the cathode is subjected for a certain time. This anodic layer hardens the surface, makes it more resistant to abrasion and improves the resistance of aluminum to corrosion and gives it a decorative appearance through a wide range of colours, which makes it an ideal solution for multiple applications, both for its excellent physical and decorative qualities.
Through its 3 anodizing plants, STRUGAL offers a wide range of colors and finishing possibilities: matt, glossy, grated, polished, etc.
With anodizing, multiple advantages are achieved:
Increase resistance to corrosion.
Increase abrasion resistance.
Increase wear resistance.
Improve protection prior to lacquering.
Improve electrical insulation.
Repel dirt and dust.
Our anodizing process has the QUALANOD quality seal.
