Background
British Castors was established in 1927 in the Birmingham area of the UK and originally were part of a foundry company that supplied metal framed beds. After a number of relocations they settled at the current site in West Bromwich in the famous Black Country and grew to be the largest supplier of castors to the retail distribution industry in the UK.
Revvo was founded in 1930 from a patent of a new “Revolutionary” castor dated 1929. Since then, the product range has expanded to offer load capacities of up to 20,000kgs.
Flexello Castors Limited was established in 1935 in the London area and designs and manufactures a comprehensive range of industrial castors and wheels that are known throughout the world. In 2001 they were acquired by the Colson Group and later relocated to the West Bromwich facility.
Global Castors founded in 1975 in Cheltenham, Gloucestershire design and manufacture a range of twin wheel castors and associated products for the furniture and bedding industry. They were acquired by British Castors in 1994 creating The Castor Company.
