Welded precision steel tubes

Welded precision steel tubes are primarily used for structural and media conveying applications due to the high degree of dimensional accuracy of the internal and external diameter – and the stability resulting from that fact.

Our wide assortment of welded precision tubes is supplemented by the coated and highly corrosion resistant Special 07, Zista 07 and Zistaplex tubes from the production of BENTELER Steel/Tube. On request, we also take on various processing assignments for our customers.
