tube specialist | stainless and seamless
stainless steel tube mill

For more than 40 years now, we have been specialising in the development and production of seamless, cold finished stainless steel tubes, nickel alloy/special grade tubes and titanium tubes within the dimensional range of OD 6.0 – 44.50. From the beginnings in the early 1980s and over the years, we have become an established and approved market leader in the manufacture of high-quality, seamless stainless steel tubes.

We realise your demand and design wishes with the highest precision, tight tolerances and an excellent surface. Thanks to our own special bending machine, U-tubes can be realised flexibly and at short notice.

Our manufacturing process is cold forming / cold pilgering and cold drawing of the tubes to the requested dimension. With our know-how and the passion for our products, this can be considered as a true refinement process.

Permanent Investments enable us to constantly develop our modern and efficient production facilities and to meet the increasing demands of our diversified customers.

Our high-quality standards and the corresponding requirements of our customers worldwide are the centre of our daily actions.

It might sound cliché but with us you actually have an agile, service-oriented and flexible partner. Whether you require our help in the daily business or have basic questions, yes even if you have strategic questions, you can be assured that we are doing our utmost to find the best possible solution for you and your partners.

This is not least due to our structures which combine the flexibility of a medium-sized and owner-operated business with the requirements of a globally acting business partner.
