In close cooperation with value chain partners including the final client, we offer safe and reliable solutions for the corrosion protection of high tensile fasteners for both onshore and offshore turbines.


Our surface treatments and gratings make a solid contribution to postponing maintenance intervals for agricultural machinery. We work together with both OEM and first and second tier suppliers.


For the international railway industry, we offer surface treatments with very precise tolerances, which are used on safety parts, such as custom-made construction parts, fastening materials and system parts for rail switches.


We produced the first gratings and stair treads for the Dutch offshore platforms in the 1970s and have continued to develop this expertise in the following decades with a wide range of grating types and options.


With professional project organisation and short communication lines, we provide the international construction sector with grating products, functional anti-corrosion surface treatments and aesthetic preservation, such as high-quality galvanising and powder coating.
