Dorman Long

Dorman Long is an engineering consultancy and equipment manufacturer for the construction of long-span bridges, power stations, refineries, offshore structures, stadia and other large building structures. Originally based in Middlesbrough, North East England, the company was a major steel producer later diversifying into bridge building. Dorman Long was once listed on the London Stock Exchange.

History

The company was founded by Arthur Dorman and Albert de Lande Long when they acquired West Marsh Iron Works in 1875. In the 1920s Dorman Long took over the concerns of Bell Brothers and Bolckow and Vaughan and diversified into the construction of bridges. In 1938 Ellis Hunter took over as Managing Director and he continued to lead the business until 1961.

In 1967 Dorman Long was nationalised, along with 13 other British steel-making firms, becoming subsumed into the government-owned company British Steel. In 1982 Redpath Dorman Long, the engineering part of the business, was acquired by Trafalgar House who in 1990 merged it into Cleveland Bridge & Engineering Company in Darlington.
