Situated in South Wales, Caparo Tubes (Tredegar) were the UK pioneers in the production of a range of quality cold-formed welded tube and hollow sections manufactured by the electric resistance welded (ERW) method of production.

The plant's three mills manufacture a range of sizes and qualities dedicated to providing customers with a product specific to their requirements supported by high service levels. Products for the structural market are manufactured to EN 10219 S275 in qualities S235, S275 and S355 as standard.

For applications where there is a requirement for enhanced impact resistance at low temperatures the Caparo developed Caparo Cold Formed S355 ma. (micro alloy) can be specified. This material gives improved weldability and enhances its suitability for the galvanising process, being superior to other higher strength options. Alternatively, EN10219 S235JRH can also be specified.

For more specific applications mechanical tubes to EN10305 E220, E260 and E320, dual certified pressure tested conveyance tube for the mechanical services and fire protection markets manufactured to both BSEN10255 and BSEN 10217-1, and scaffolding tube to EN39 are produced. Where further processing is required a range of facilities to cover the needs of the market is available.

In addition to longitudinally welded tube the spiral mill facility produces tubes from 400mm dia to 1575mm dia, which are welded both internally and externally providing additional strength over conventional single weld tubing.
