Surface finishing using the anodising process

Our strength is particularly evident in the surface-finished version:

We offer anodising according to DIN 17611 for interior and exterior applications in the common anodising shades. Our standard coating thickness for interior applications is 10 - 12 µm. Please select the pre-treatment required for your application from Table 1. In table 2 you can find the standard anodised colours. Of course, we're also happy to supply you with special colours.
