On the Sheffield Road site, a narrow, triangular section of land between Sheffield Road and the Sheffield to Doncaster railway line, opposite the Imperial site was at its apex the Magnet Dept, the steel heat treatment and warehousing section and, opening in 1927, the first high frequency steel melting plant in the country. Fronting Sheffield Road were the main company offices. A memorial to those workers from the company who lost their lives in World War I was fixed to the wall adjacent to the main doors.
