Roll Cage tube Supplier

ProFormance Metals are considered worldwide to be a number one supplier of Roll cage tube and other specialist metals and plastics used in the Motorsport, Automotive, Defence and Niche vehicle sectors.

We manufacture, stock and supply various grades of roll cage tube and even have created our own grade of material that is FIA and MSA approved called ROPT510 (Roll Over Protection Tube: 510 Nmm2 min tensile, 370 N/mm2 min Yield)

With no minimum order charge and our minimum quantity of supply being 1 length of tube, we can cater for small roll cage adjustments, project builds to full works team preparation.


We pride ourselves on providing high quality materials only produced from approved manufacturing sources, all of which are fully traceable and supplied with certificates upon request.


The advantages of a bespoke roll cage :
  • The Roll Cage is manufactured to fit your car, with no modifications from an off the shelf product.
  • The grade of roll cage tube used is controlled via our certification and quality approvals on the distribution of steels.
  • Certification will be in your name and therefore can be traced alongside other vehicle records
  • Continuity of materials are controlled in terms of tensile strengths and elongation (formability). We have manufacturing facilities producing tubes against our specification (ROPT510) – This is of particular importance to roll cage installers and tube manipulators to ensure the same level of quality of roll cage is produced each time.
  • Purchasing direct from us as a stockholder will ensure you are paying the best price for the tubing used.
  • Tubes supplied will be guaranteed to exceed MSA and FIA regulations
    Our network of cage fitters and fabricators can help you with either a local installation or the best in the business for your needs.

We are also able to supply finished parts varying from single hoops to full homologated cage structures.

Roll Cage

A roll cage is a specially engineered and constructed frame built in or around the passenger compartment of a vehicle to protect its occupants from being injured in an accident, particularly in the event of a roll-over.

There are many different roll cage designs depending on the application, hence different racing organisations have differing specifications and regulations.

Another benefit of a roll cage is that it will also help to stiffen the chassis, which is desirable in racing applications.

The ProFormance Metals stock range caters for MSA National, SFI and FIA International cage manufacture.


Roll Bar

A roll bar is a single bar behind the driver that provides moderate roll over protection. Due to the lack of a protective top, some modern convertibles utilise a strong windscreen frame acting as a roll bar. Also, a roll hoop may be placed behind both headrests (usually one on older cars), which is essentially a roll bar spanning the width of a passenger’s shoulders.

Roll Over Protection Structure

ROPS refers to operator compartment structures (usually cabs or frames) intended to protect equipment operators and motorists from injuries caused by vehicle overturns or rollovers.

Aluminium Flat Sided Oval

We received an enquiry from an automotive company based in the USA looking for the supply of a flat sided oval in aluminium. The flat sided oval shape is predominately  found in ERW seamed steel material and would have weight implications for this particular component.

Working closely with designers, we were able to select a size from the tooling range available and enabled the forming of an aluminium round tube already held in stock and produce a flat sided oval on a very short lead time.

The custom production of a small batch produced a weight saving benefit of 0.68kgs per metre (compared to nearest available steel dimensions) and enabled prototype work to commence.



We are currently awaiting the results of prototyping and hope to update at a later date with results.

ROPT510 Aerofoil & Streamline tube

We have just completed a re rolling requirement for a customer that has been commissioned to produce scale models of various race cars and other Motorsport related vehicles.



The end use was for a static display vehicle and material strength did not have to be a major factor, but to re profile to a  finished Streamline / Aerofoil, a cold drawn seamless had to be used.

ROPT510 Roll over protection tube Streamline teardrop for wishbones


The decision was made to use our ROPT510 round tube and re roll into the streamline tube shape as set by our customers’ drawings.

The benefits of using the ROPT510 in this application were to minimise costs, but maintain a quality finish of the streamline due to the high forming properties the ROPT510 possesses.
