Anodization coloursProcess of anodizing


The work pieces are to be prepared prior to the application of the anodization process. The anodization procedure complies with DIN 1761, both when there is no chemical pre-treatment (DIN 1761: E0, technical surface) and when there is chemical pre-treatment (DIN 1761: E6, decorative, flat-stained surface).


Anodizing is accomplished through electrolysis. This means that the pores will be opened, so that the pores can be dyed.

Work pieces up to 6m length, 0,8m width, 1,9m depth and 1.200kg can be treated with the anodization procedure.


After anodization, the open pores must be sealed again. This is achieved through cooking in demineralized water.

With the anodizing process, work pieces can be anodized in a colorless state, or dyed in various colors. By default, Laengle offers the following shades (Euras Standard):


  • C0 Natural clay
