Quality in fifth generation

With our ambitious employees at the Heidenheim site, we offer our customers high-quality pipe bends and vessels. We deliver these in the required time and respond flexibly to our customers’ wishes. We also support our customers in the development of new products and continue to develop ourselves. We regularly review these continuous improvements both internally and externally. Due to our own training, our employees are always very well qualified and up to their requirements.

The fact that we implement this quality policy consistently and at all times can be seen from our satisfied customers and, above all, their current feedback.


We are happy to remember a few very special milestones in our company’s history as we continue to work towards an even better future!
