Safety Cage Tubing

For automobile roll cages, a specialist grade of steel is used and manufactured to a unique standard. Industrial Tube’s carbon tube for Roll Cages is manufactured in compliance with the Motorsport MSNZ- Q29. 38.1mm available in 5.5m lengths. 44.5mm available in 4m lengths.

Yes. UltraTubeRS™ can be bent using common motorsport bending equipment, including manual and mandrel rotary draw benders.

Validation bending has included tight 2D centreline radii using mandrel bending, as well as use on pull‑type benders such as ProTools and JD2. Behaviour is consistent with expectations for high‑strength tube.

Yes. UltraTubeRS™ is compatible with standard TIG welding and MIG welding processes used in motorsport fabrication.

TIG welding is generally preferred for critical structural applications, particularly where thinner wall sections are used, due to its high level of control over heat input and weld profile. MIG welding can also be used with appropriate technique, with pulsed transfer modes recommended to assist in managing heat input.

Filler material should be slightly undermatched relative to the parent material. Common examples include ER70S-2 and ER70S-6 or equivalent grades. Preheating and post-weld heat treatment are not typically required under normal fabrication conditions.

As UltraTubeRS™ is supplied in a heat-treated condition, welding heat input should be controlled to the minimum required to achieve full penetration.

Independent testing has shown that UltraTube RS delivers tensile strength comparable to 4130 chromoly while exhibiting more progressive deformation behaviour and a less severe weld-zone hardness increase after TIG welding. Material selection should always consider the specific application, design and fabrication requirements. For a detailed technical comparison, download the study below.

Use of any material depends on the rules of the relevant sanctioning body and class. Builders should always confirm acceptance with their governing body or scrutineer for their specific application.

In many rule sets, material used outside the principal safety cage structure (such as lower chassis rails, secondary bracing, or non‑rollover‑protection members) is treated differently to main roll‑over structures. Applications in these areas are typically less restrictive, but confirmation should always be obtained for the specific class and vehicle.
