About UltraTube
UltraTube is a high-performance steel tube made from advanced dual-phase (DP) steel. Its ferrite–martensite microstructure offers a unique combination of high strength, good ductility, and excellent weldability.
UltraTube is designed for weight-efficient designs in motorsport, off-road, automotive, and safety-critical applications where strength, reliability, and fabrication ease are essential. Its dual-phase microstructure offers the strength and formability required for complex geometries that are often difficult to manufacture using conventional alloyed high-strength steels.
The mechanical characteristics of UltraTube – high energy absorption, excellent fatigue resistance, and consistent performance – make it well-suited for safety cages, space frames, commercial vehicle fit-outs and heavy-duty off-road accessories. Its ability to deform in a stable, controlled manner helps maintain a low deceleration pulse during impact, improving crash performance and occupant protection.
Dual-phase steels exhibit continuous yielding, transitioning gradually from elastic to plastic deformation rather than showing a distinct yield point. This results in more
predictable behaviour during both forming and impact scenarios.
The cold-rolled coil used to manufacture UltraTube is produced through intercritical annealing on a continuous annealing line (CAL). This process precisely controls phase
transformations to achieve the dual-phase structure, ensuring uniform thickness and consistent mechanical properties throughout the coil and into the final tube.
Industrial Tube Manufacturing’s precision tube-forming process uses high-frequency induction (HFI) welding to produce a tube with excellent dimensional accuracy, a minimal internal weld bead, and a narrow and controlled heat-affected zone (HAZ). The result is a clean, consistent tube optimised for demanding applications where strength and reliability matter most.
