Pickled Tubes & Profiles


We produce tubes and tube components from pickled steel for a whole variety of requirements, ranging from the purely functional to the ready-to-install, and from standard cross sections to elaborate profiles.

Our wide range of the latest machinery combined with a vast pool of know-how means we can deliver just about any technically feasible solution. Our standard product range includes round, elliptic, oval, triangular, rectangular, and polygonal tubes. In addition, we can produce customized profiles to extremely low tolerances in a wide range of cross sections and wall thicknesses.
