Our anodizing capabilities include:

  • Clear Anodizing up to 31’
    A widely used anodizing method typically involving sulfuric acid anodize followed by hot water seal.
  • Two-Step Anodizing
    Also known as electrolytic coloring; after anodizing the metal is immersed in a bath containing an inorganic metal salt. Current is applied which deposits the metal salt in the base of the pores. The resulting color is dependent on the metal salt used and the processing conditions.
  • Hard Coat Clear
    An electrochemical process that provides clear corrosion protection to aluminum and aluminum alloy parts or pieces.
  • Acid Etch
    An alternative chemical etching process that produces a superior finish compared to traditional caustic etch anodizing. Acid etching is performed in the pre-treatment cleaning of aluminum profiles, before the anodizing process.
  • Traditional Caustic Etch
    This chemical treatment is done prior to anodizing to improve the final appearance of the anodized part.
