Pickled Tubes & Profiles

Functionality, economy and tightest tolerances for perfectly fitting final products

Tubes, tubular components and profiles made of pickled steel - including high-strength steels, complex and duplex steels - meet a wide range of requirements: From pure functionality to ready-to-install solutions, from simple cross sections to sophisticated special profiles.
Our comprehensive, state-of-the-art machinery and the know-how of our employees enable us to provide practically all solutions that are feasible. Our standard program includes round tubes, elliptical tubes, oval tubes, triangular tubes and profile tubes. In addition, we manufacture special profiles according to customer specifications in a wide range of cross-sections and wall thicknesses with the narrowest tolerances.

What are our quality standards?

Our quality standards for pickled tubes are unique:
•    Production of pipes in the wall thickness range of 1 mm
•    Continuous inline pipe measurement
•    Continuous weld seam quality monitoring
•    Free choice of weld seam position - this also applies to  corners
•    Production with tightest tube tolerances inside and outside of +/- 0.1 mm
•    High radial runoutaccuracy up to 0.08 mm
•    Tightest wall thickness tolerances up to +/- 0.02 mm
•    Highest surface requirements for further processing

What are the characteristics of our premium tubes?

Premium tubes from Wuppermann meet particularly high quality standards. They can be produced with external and internal tolerances of less than +/- 0.1 mm and wall thickness tolerances of up to +/- 0.02 mm. Even tighter tolerances are possible for round tubes. Here the external / internal tolerances are within +/- 0.05 mm.

For which final products are our pickled tubes and profiles used?

Our pickled tubes - especially the premium tubes - are used in the furniture industry. They are mainly used for furniture where tubes are used as precisely fitting components and must be telescopic, for example, for a height-adjustable desk. Other final products include various tubular components for various frames, including chair frames, radiators and specific applications in the automotive industry, which are implemented according to clear standards and specifications.
