Optimized surfaces with perfect properties

We are experts in surface treatment and finishing.
In our work, we aim at achieving technically functional and simultaneously decorative surfaces.

After sandblasting, grinding, polishing, painting, coating and electroplating,
the high-grade surfaces look noble and are well protected against external influences.

For efficient corrosion protection

In our ultramodern electroplating unit we apply coats of copper-nickel, chromium and brass.
Our technology makes this process very efficient and ecologically compatible.

For finer surfaces

In compressed air blasting, sand is used as an abrasive that changes the surface.
By means of this method we remove rust and other dirt particles and create a fine matted surface design.

For surfaces with the right properties

We polish, grind and brush various surfaces.
By removing irregularities, we provide the metal with a special texture.
In the process, we rely on our state-of-the-art machinery and our perfectly trained employees.

For a beautiful appearance with an additional benefit

Our paint shop provides surfaces with a decorative appearance. However, the right paint
may also be a means to preserve the value or to ensure the technical requirements of your application.

For components with your sign

We use cutting-edge laser technology to mark your parts of chromium, nickel, or plastic.
A laser-engraved logo and individual inscription will increase the recognition value of your enterprise.
