UltraTube RS™: a modern alternative to traditional high-alloy steels.

UltraTube™ and UltraTube RS™ – New Steel Options for Builders Who Push Limits

Industrial Tube Manufacturing introduces UltraTube™, a new generation of high-strength precision tubing engineered for strength, reliability, and ease of fabrication.

Developed from the same OEM-grade dual-phase steels used in modern automotive safety cells and structures, UltraTube™ combines high yield strength (650 MPa +) with exceptional ductility and weldability. It’s strong where it counts, yet straightforward to work with – a practical step forward for fabricators looking for consistency and performance from locally made Precision Steel Tube.

Developed to give New Zealand and Australian fabricators access to the same advanced steels long used in global automotive manufacturing, UltraTube™ provides the opportunity for well-engineered designs to reduce weight without compromising safety or reliability – and it’s made right here.

Stronger, Lighter, Easier to Work With

UltraTube™ is manufactured from cold-rolled dual-phase steel using a precision cold-forming and high-frequency induction welding (HFIW) process. Every length is dimensionally accurate, mechanically consistent, and fully traceable. The result is predictable bending and forming behaviour and a high-grade surface finish – ideal for applications where process consistency and presentation matter.

With its combination of high strength, energy absorption, and fatigue resistance, UltraTube™ is suited to:

Commercial vehicle fit-outs
4WD and off-road accessories
Structural frames and engineered assemblies

For fabricators accustomed to 4130 ‘Chromoly’, UltraTube™ provides a modern, weld-friendly alternative – no pre-heat or post-heat required and compatible with standard filler materials. Available in a stocked range of circular profiles, with square, rectangular, and oval options produced to order (MOQs apply).

Motorsport Innovation: UltraTube RS™

Built on the same platform, UltraTube RS™ is the performance-validated variant developed for motorsport safety structures. Produced under strict process control with independent tensile testing to AS 1391, every order of UltraTube RS™ is supplied with full Material Test Certificates for complete traceability, and permanent line-marking for easy identification – providing verified mechanical performance and confidence for safety-critical applications. UltraTube RS™ is designed as a direct alternative to imported 4130 Chromoly, BS4 T45 and Docol R8 and is manufactured in a full range of motorsport relevant sizing from 22.2-50.8mm (7/8″-2″).

Mechanical Properties (UltraTube RS™)

Yield Strength Rp0.2 (min): 650MPa
Tensile Strength Rm (min): 800MPa
Elongation A50 (min): 14%
Hardness (Typical): 104 HRB

Testing shows consistent mechanical properties of more than 650 MPa yield and 800 MPa tensile strength with stable deformation behaviour under impact. UltraTube RS™ is currently pending approval across multiple motorsport sanctioning bodies in Australasia, and has already proven itself in prototype builds – including the University of Waikato’s Formula SAE chassis fabricated entirely from UltraTube RS tubing.

Made Here. Supported Here.

UltraTube™ and UltraTube RS™ are manufactured in New Zealand to AS 1450 and EN 10305-3 dimensional standards, supplied with full mill certification and traceability. Backed by local technical support and fast delivery across Australasia, the range gives engineers and manufacturers the confidence to specify high-performance tube that meets today’s engineering priorities – lightweighting, safety, and efficiency – without the need to import or compromise.
