Welded tubes and profiles
according to EN10305-3/-5
The welded pipe can be used directly from the machine. Developments in recent years have continuously optimized this product group.
In addition to the standard raw materials, high-strength dual and complex-phase steels can also be welded. The tubes achieve strengths of more than 1200 MPA. Welded pipes are used in many areas due to their tolerances, straightness properties and the one-step manufacturing process.
Round, rectangular or flat oval tubes – many shapes can be produced directly.
Our product portfolio includes round, rectangular and flat oval tubes. The surface of the steel tubes is also suitable for a direct coating process. Alternatively, the tubes can also be manufactured from galvanised strip.
Areas of application for welded tubes in the automotive industry
Welded tubes are used in the automotive industry in the following components, among others:
- Front and rear seat structures
- headrests
- Chassis and structural components
- Cooling loops for batteries
- Trailer couplings
- Hinge brackets
Welded tubes are also required in many areas of the furniture industry:
- Cantilever chairs
- Chairs
- School desks
- Height-adjustable desks
Our welded tubes are also used in logistics, e.g. as support rollers for transport systems, frame parts for floor conveyor systems or in container construction.
