Walter T Glover established his wire manufacturing company in 1868, occupying premises at the Bridgewater Street Iron Works in Salford. W T Glover & Co, known as Glover’s, originally made cotton-covered and braided, insulated copper wires for use on bell, signalling and telephone circuits. As trade developed, the company moved to the Springfield Lane Cable Works in 1880. At this time, factories and larger private homes were beginning to install electric lighting, which required better insulated cable. Glover's started to manufacture cables covered with between one and three layers of rubber strip, waterproof tape and compounded cotton braid. In the late 1880s, Glover's began to make lead-sheathed cables for underground use. The company became a limited company and moved to Trafford Park in 1898, securing the exclusive rights for the supply of electricity to all the roads, streets and premises of Trafford Park. In June 1919, Vickers Ltd took over Glover's. Although Vickers held most of the shares, Glover's kept its name and management. In 1929 the Vickers group reorganised and sold its shares in Glover's to Sir Tom Callendar of Callendar Cable and Construction Co. Some shares later went to W. T. Henley's Telegraph Works Ltd. and British Insulated Cables. In 1945, Glover’s became part of British Insulated Callenders Cables Limited, following the merger of Callenders Cable and Construction Co and British Insulated Cables. During the 1950s, Glover’s developed high voltage submarine power cables, used to link centres of population with sources of generation. The parent company formed a subsidiary, BIC (Submarine) Cables Ltd, to manufacture and install the Glover’s cables. Glover's submarine cables linked England and France, and the north and south islands of New Zealand. Increasing competition from other cable manufacturing companies resulted in the south side of Glover’s Trafford Parks works integrating with the newly formed Wiring and General Cables Division of the British Insulated Cables Company (BICC). The Trafford Park factory closed in 1970, but the Glover’s brand continued as part of BICC.

The Ford company was established in Great Britain in October 1910. In order to promote the company's desire to be seen as a company building cars for the British market using locally sources parts put together by local employees, the Ford Motor Company (England) Limited was established in 1911. At the same time the company moved from London to a new factory at Trafford Park, Manchester. The success of the company continued and as a result larger premises were required, the company chose a site in Dagenham on the banks of the River Thames and eventually the new plant was opened there in 1931. The Trafford Park factory continued to operate whilst Dagenham was being built and as a shadow factory, during the Second World War, building Merlin engines until 1946, when production was stopped and the factory was sold.
