Anodizing

What is Anodizing?

When aluminum surfaces are exposed to the atmosphere, a thin invisible oxide skin forms immediately, protecting the metal from further oxidation. Anodizing is an electrolytic process that adds to the protection provided by aluminum's natural oxide layer.

 

What are the Benefits of Anodized Aluminum?

  • Corrosion Resistance- Although aluminum doesn’t rust, it can deteriorate in the presence of oxygen. Anodizing greatly increases aluminum’s resistance to corrosion and atmospheric agents.

 

  • Aesthetics- Unlike other surface finishes in which a separate coating is applied, the anodized coating is an integral part of the aluminum surface, aesthetically appealing and architecturally harmonious.  

 

  • Ease of Maintenance- Anodized finishes resist staining and scratching and are easily cleaned with mild detergents.

 

  • Durability- Anodized aluminum has a long lifespan as the anodic layer is nearly diamond-hard, and the finish doesn't wear off as it is part of the metal itself.
