to the highest standards

We trust in the quality of our reservoirs and rely on our own production. In our workshop, we use our CNC machines to manufacture individual one-offs, series production for companies and end customers, as well as prototypes and further developments. Our location in Rostock plays an important role here, because it not only serves as a production site, but also as a research and development center.


A center of innovation and research

The Rostock location plays a crucial role for Stealkey Customs. Our own production facility and our research and development center are located in this northern German Hanseatic city on the Baltic Sea. Thanks to our local presence, we are able to respond flexibly to the requirements of our customers and ensure fast and efficient production.
