Dorman Long, based in Middlesbrough, England, are a major manufacturer and fabricator of steel components and structures . They have been involved in the manufacture and construction of many major bridges since 1875, including, in 1932, the Sydney Harbour Bridge.
The firm began as an iron and steel works manufacturing bars and angles for ships. A natural progression from this was to become involved in the construction of bridges, particularly when Dorman Long took over the concerns of Bell Brothers and Bolckow and Vaughan in the late 1920s. In 1990 they were merged with The Cleveland Bridge & Engineering Company, Darlington, and are still involved in the design, manufacture, fabrication and erection of many different types of structures such as bridges, buildings, offshore platforms, airports, etc, with one of the most recent high profile contracts, being the new Wembley Stadium in London, England.
