YANGSEN TUBE
We develop and produce rolled and drawn precision and profile steel tubes for various industrial sectors using tailored materials and processes.
Reinforcement tube
Jansen Steel Tubes manufactures welded precision steel tubes and profiles used as structural reinforcements in the automotive industry. High-tensile materials are used for the structural reinforcement tubes. Applications within this automotive industry segment are very sensitive to quality and component failure in the event of an undesired deformation of the component may have serious consequences. The tight production tolerances guarantee efficient and thus cost-effective tube processing during component production. The use of new modern air-hardening materials allows a significant reduction of the work involved by abolishing the tempering process, and thus a significant reduction in costs.
Tube requirements
■ Excellent formability
■ High levels of fatigue strength
■ High levels of strength and hardness according to Q+T
■ Excellent surface conditions
