Steering
Jansen Steel Tubes produces welded and welded-drawn precision steel tubes and profiles for steering systems made of standard materials as well as high-tensile materials. The applications in steering construction are very critical to quality. The tubes' tight tolerances and very good reshaping properties ensure a smooth component production. The use of modern high-tensile materials allows further weight savings by reducing the wall thickness while maintaining the component's strength.
