NEW addition - welded steel construction tubes
We are pleased to announce that we have expanded our product range to include structural steel seam pipes. This is a group of products that is widely used in many industries and construction, thanks to its good strength properties and attractive quality-to-price ratio.
Our offer includes welded pipes made of steel grade S235JR. After the manufacturing process, the finished product (seamed pipe) in the designation receives the letter H (hollow) at the end, indicating the application for pipes, and the final designation S235JRH is formed.
Closed sections produced by cold bending, are made of unalloyed structural steels, fine-grained structural steels. Cold-bent hollow sections have wall thicknesses of up to 30 mm.
Welded structural tubes meet the conditions specified in PN-EN 10219-1:2007 and PN-EN 10219-2:2007 named Cold-bent hollow sections made of unalloyed and fine-grained structural steels (Part 1: Technical conditions of delivery, Part 2: Tolerances, dimensions and static sizes).

Manufacturing process of seamed structural pipes
Seam pipes are obtained by bending or coiling the strip so that the edges can be joined together by welding or welding. Strip coiling makes it possible to produce helically welded pipes with varying diameters depending on the angle of the helix, the helical line. Production of pipes by bending begins with the preparation of a steel strip or sheet, which is then unrolled and straightened accordingly. In the next stage, the sheet passes through a series of profiling rollers, where the ends of the sheet are bent and formed into the shape of a pipe. The edges of the formed pipe are joined by electric welding or welding, which ensures the formation of a strong joint.
Seam pipes in our offer are produced by bending, and the ends are joined by high ferquency induction (HFI) welding. This is an induction welding in which the joint is formed by pressing together parts heated locally by eddy currents created under the action of an alternating magnetic field.
After the welding process, the pipe is cooled and then calibrated and straightened to achieve the correct dimensions and ideal cross-sectional geometry. At a further stage, quality inspections, including non-destructive testing of the welds, are carried out to ensure the safety and compliance of the product with the relevant standards. Finished pipes are cut to the required lengths and, if necessary, subjected to additional surface finishing.
