Providing structural rigidity in motor sport applications.
The primary purposes for a safety cage / roll cage are to protect the vehicle’s occupants in the event of a roll-over and provide structural rigidity in motor sport applications. The high-strength properties of Industrial Tube’s Safety Cage tube ensures that the safety cage can withstand significant forces during a roll-over or crash, providing crucial protection.
Industrial Tube has an unmatched track record in the safety cage, roll cage application, backed by stringent testing and quality control. With over 170,000 metres of safety cage tubing for Motorsport and Roll-over protection systems (ROPS) produced and supplied across New Zealand and Australia over the past 15 years.
Industrial Tube’s Mild Steel Roll Cage Tube is manufactured in New Zealand to MotorSport New Zealand’s ITM-MSNZ-Q29 standard. Not approved by Motorsport Australia; sold for commercial ROPS.
UltraTube RS™ is a New Zealand–manufactured dual-phase steel tube, engineered specifically for motorsport safety cages. It delivers over 650 MPa yield strength with excellent ductility, progressive strain hardening, and proven crash energy absorption.
