We use low-carbon steel

Quality raw material

The company manufactures electro-welded tubes of different geometry and dimension: round, square, rectangular, oval, semi-oval, elliptical, with special sections.
The so-termed precision tubes are processed in a variety of ways:

  • From hot rolled pickled strips;
  • From cold rolled strips;
  • From zinc-coated strip;
  • From high-strength strip (pickled, cold-rolled, zinc-coated);
  • From dual-phase strip;
  • From other materials upon request.
