Anodising Finishing

One of the best techniques for finishing aluminium is the anodising process. The electrolytic oxidization produces a protective ceramic layer on the surface of the metal. The aluminium becomes more resistant and completely new design options become available due to this pre-treatment method

We use the following colouring techniques:

  • Adsorption
  • Absorption
  • Electrolysis
  • Colouring using alloy components

Aluminium surface identification

So as not to lose the overview of the many design options, we at GRONBACH use EURAS and DIN 17611 for identification purposes. Should something special be required, we have our applications specialists on hand as well as our own surface identification system.
