Providing structural rigidity in motor sport applications.
The primary purposes for a safety 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.
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 has an unmatched track record in this critical application, backed by stringent testing and quality control.
