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
Starting with circular tubes, which are annealed and prepared for drawing, the final shape is achieved after one or more further processes. Steel is a very good material to form. A wide range of shapes, wall thicknesses, materials Coordinated production processes depending on order requirements and quantities Batch sizes available from a few hundred metres Very narrow tolerances
