Technical Specifications

British Standard T45 is a carbon-manganese steel tube supplied in the hardened and tempered condition. The T45 is a well-established product within the aerospace industry, having been used originally in the fuselage detail of Spitfire and Hurricane aircraft. Its high strength properties ensure that it will continue to be an essential material for both the aerospace and motorsport industries.

T45 is easy to weld and to form, and this quality combined with supreme high strength and relatively low weight makes it a popular choice for many of our clients.

Historically and presently, the T45 has found many applications in the aerospace industry, and also within the modern motorsport industry. It has been used to create roll cages, pilot seats, cassis, and much more.
