Welded tubes

Hydro stands for high-quality, longitudinally seam-welded aluminium tubes. As the leading manufacturer, we specialize in the production of precision tubes for technically exacting, value-added applications in light vehicles. Our aluminium tubing, which is well suited to bending, swaging, flaring and hydroforming processes, is characterized by close geometrical tolerances and high surface quality – ideal for meeting the tight package requirements of modern car design.

Our tube solutions include:

• Chassis subframes
• Engine cradles
• Propeller shafts
• Body frames
• Structural components
• Instrument panel beams
• Radiator supports
• Crash elements
• Shock absorbers
• Pistons for air-suspension systems

Adding to a wide range of application possibilities
Longitudinally seam-welded tubes can be produced in many different cross-sectional shapes for use in a range of applications. Decisive is the outstanding formability of the alloys used (high elongation) and the high reproducibility of the manufacturing process (tight tolerances).

Longitudinally seam-welded tubes are the convincing solution because of their outstanding forming properties and high cost-effectiveness. In large batches, they are particularly attractive for automotive applications. Thin-walled, large-diameter tubes can be manufactured easily. Precision and quality are also assured at low processing costs.
