Profile steel tubes

Precision and profile steel tubes from Jansen are as individual as the requirements of our customers. Therefore we focus our production competences completely on the provision of tailor-made solutions. Our comprehensive quality management system guarantees perfect process operations and consistency throughout: from technical advice through individual processing steps to logistics services. Regular random sampling substantiates our quality requirements and ensures that form and function are in harmony from the raw material to the end product.

Our range of profiled steel tubes includes square and rectangular tubes as described in EN 10305-5.
Jansen has further extended this product group with more shapes and different edge designs.

Welded, cold rolled

During the rolling of the tube, the shape is determined by the outer tools.
Individual diameters and wall thicknesses with narrow tolerances
Different materials
Wide diversity of shapes
Surfaces with skin pass rolling
Controlled weld quality
Heat treatment
