Overview
Richard Thomas and Baldwins Ltd, commonly abbreviated as RTB, was a major British iron, steel and tinplate producer whose operations were concentrated principally in Wales. The company was created in 1948 through the merger of Richard Thomas & Co Ltd and Baldwins Ltd, bringing together two established industrial groups with deep roots in the nineteenth-century development of the British iron and tinplate industries. Richard Thomas & Co had grown from the activities of Richard Thomas, who leased tinplate works at Lydbrook in Gloucestershire in 1871 and at Lydney in 1876. The business expanded through acquisitions of local collieries and the purchase of the Melingriffith Tin Plate Works near Cardiff in 1888. Under Richard Beaumont Thomas, who succeeded his father as managing director, the company became one of the United Kingdom's principal tinplate manufacturers. Its later expansion into integrated iron and steel production included the takeover of the Ebbw Vale Steel Iron and Coal Company in 1936, followed by construction of a new steel plant and strip mill at Ebbw Vale. Baldwins originated as EP&W Baldwin, an ironfounding business based at Stourport. Alfred Baldwin became its sole proprietor in 1870, while retaining the established trading name. In 1888 he brought his son Stanley Baldwin into the business; Stanley Baldwin later became Prime Minister of the United Kingdom. The company was incorporated as EP&W Baldwin Ltd in 1898 and progressively acquired tinplate works, particularly in South Wales. The merged RTB combined raw-material interests, iron and steelmaking capacity, strip-milling facilities and a substantial portfolio of tinplate works. In 1948 it introduced the first continuous tinning line at its Ebbw Vale tinplate works, an important development in the mechanisation and scale of tinplate finishing. RTB also undertook major greenfield investment during the post-war period. The most significant project was Spencer Steelworks at Llanwern, east of Newport, which was officially opened in 1962. The works were named after H. F. Spencer, RTB's managing director when construction was announced in 1956. RTB's ownership changed as British steel policy shifted between nationalisation and proposed privatisation. The company was nationalised in 1951 and placed under the Iron and Steel Corporation of Great Britain. In 1953, under a Conservative government, it was transferred to the Iron and Steel Holding and Realisation Agency in preparation for possible privatisation. Its scale made a sale difficult, however, and the company remained in public ownership. In 1967, the steel industry was nationalised again under the Iron and Steel Act, and RTB was absorbed into the newly established British Steel Corporation rather than continuing as an independent company. The RTB corporate entity is therefore defunct, although important facilities and industrial assets associated with its former operations continued within successor steel organisations. The business ultimately became part of the corporate lineage that now forms part of Tata Steel Europe. RTB's historical significance lies in its role as one of Britain's largest steel companies, its integration of coal, iron, steel and tinplate production, and its contribution to the industrial development of South Wales.
History
The industrial history behind Richard Thomas and Baldwins began with two separate nineteenth-century businesses. Richard Thomas developed a business in iron, tinplate and coal after leasing the Lydbrook tinplate works in Gloucestershire in 1871 and the Lydney works in 1876. He expanded through local colliery acquisitions and, in 1888, acquired the Melingriffith Tin Plate Works near Cardiff. His company became an important British tinplate producer, and his son Richard Beaumont Thomas took over as managing director in 1888. The Richard Thomas business later moved further into integrated steel production. In 1936 it took over the Ebbw Vale Steel Iron and Coal Company. A new steel plant and strip mill were subsequently built at Ebbw Vale, strengthening the company's position in South Wales and connecting its tinplate activities with a broader iron and steelmaking base. The second predecessor, Baldwins, began as EP&W Baldwin, an ironfounding firm at Stourport. Alfred Baldwin bought out his relatives in 1870 and became the sole proprietor while retaining the firm's original name. In 1888 he brought his 21-year-old son Stanley into the enterprise. Stanley Baldwin later became Prime Minister of the United Kingdom. EP&W Baldwin Ltd was incorporated in 1898 and expanded by acquiring tinplate works, mainly in South Wales. These two industrial groups were combined in 1948 to create Richard Thomas and Baldwins Ltd. The merger produced a large, geographically concentrated steel and tinplate company with interests extending across ironmaking, steelmaking, strip milling, tinplate production and coal. One of the new company's early technological developments was the introduction in 1948 of the first continuous tinning line at its Ebbw Vale tinplate works. RTB was affected directly by post-war changes in the ownership and governance of British steel. In 1951 it was nationalised and placed under the Iron and Steel Corporation of Great Britain. After a change of government in 1953, it was transferred to the Iron and Steel Holding and Realisation Agency in anticipation of possible privatisation. The company's size and strategic importance made disposal difficult, and it remained in public ownership. The company's principal post-war expansion project was Spencer Steelworks at Llanwern, east of Newport. Construction was announced in 1956, during the management of H. F. Spencer, and the new greenfield works officially opened in 1962. The project represented the scale of capital investment then being directed toward modernising British steel production and expanding capacity in South Wales. In 1967, the British steel industry was nationalised again under the Iron and Steel Act. RTB was absorbed into British Steel Corporation, ending its existence as an independent company. Its former operations entered the successor structure of the British steel industry and, through later corporate changes, the business lineage associated with the former RTB operations ultimately became part of Tata Steel Europe. The company's legacy is consequently institutional as well as industrial: it linked older South Wales tinplate works with modern integrated steelmaking and became one of the principal predecessors of later British and European steel operations.

Products and positioning
A vertically integrated British steel and tinplate producer with a major industrial presence in South Wales.
TinplateMetal products
Tinplate was one of RTB's defining product areas. The company inherited and expanded a network of tinplate works in South Wales and Gloucestershire through its predecessor businesses. Its 1948 introduction of a continuous tinning line at Ebbw Vale represented a significant move toward continuous, large-scale finishing of steel coated with tin.
Steel stripFlat steel
RTB produced steel strip through the Ebbw Vale complex. The strip mill was developed after the 1936 takeover of the Ebbw Vale Steel Iron and Coal Company and supported the company's integrated steel and tinplate operations.
Iron and steelPrimary metals
The company operated across iron and steel production rather than functioning solely as a finishing business. Its assets included steelmaking capacity at Ebbw Vale and the later Spencer Steelworks at Llanwern, reflecting RTB's role as one of the United Kingdom's largest integrated steel producers.
Coal and colliery outputMining inputs
Through Richard Thomas & Co, the company's predecessor structure included ownership or control of local collieries. These interests supplied part of the industrial base associated with an integrated iron, steel and tinplate producer.
