Surface treatment

We anodize (almost) everything
Surface treatment and anodizing, Hydro Aluminium Raeren SA
During anodizing, the oxide layer on the surface of the aluminium is thickened using an electrochemical process. In this process, the natural aluminium colour can be maintained, but many other colours are also available.

Advantages of anodizing 

  • aesthetic reasons
  • corrosion resistant
  • specific surface structure
  • surface hardness
  • durability
  • reflection ability
  • electrical insulation

Even in its natural state, aluminium has a decorative surface with good corrosion resistance. However, if you would like greater protection or another colour, we can anodize or paint the aluminium profile without any difficulty.

At our extrusion plant in Raeren we have the possibility of anodizing all kinds of aluminium products – from processed individual parts to profile lengths of 7.5 m. And if you need longer profiles, you can count on our partners, who work to our quality standards.

We can also paint your profiles, whether it is with wet paint or by powder coating. The selection of colours is infinite. Paint gives the aluminium a decorative appearance and also protects the profile from corrosion and temperature fluctuations.

There are even more surface treatments available: for example coating with Teflon or other films, screen printing or grinding, polishing or barrel finishing.
