Helical Bar was incorporated as a limited company on 3 July 1919. Originally known as The Helical Bar and Engineering Company Limited its main business was the manufacture and sale of reinforcing steel for the construction industry. Continuing this business for over 65 years financial difficulties led the Company to seek new activities and on 21 August 1984 Michael Slade was appointed to the Board bringing with him over 15 years of experience of the commercial property world. The subsequent sale of the steel reinforcement business to its management at the end of 1986 left Helical Bar a property development and investment company with Michael Slade as its Chief Executive and Nigel McNair Scott as its Finance Director. Gerald Kaye joined the Board in 1993 Matthew Bonning-Snook and Jack Pitman in 2007.
