In 1946 steel plate rolling ended. In 1953 the continuous bar mill was completed, which was to roll both straight and coiled bar. In 1963 the new site covered some and the Roundwood site, beside the Midland Main Line north of the main works, and covering another was starting production. The plant then included two mechanically-charged blast furnaces feeding 10 open hearth steel making furnaces which, in turn, fed two primary mills for rolling blooms and billets and six finishing mills rolling a wide range of blooms, billets, slabs, sections, bars and strip. The Roundwood site had an 11" continuous bar mill and a narrow hot strip mill. Capacity at the time was about 425,000 tons of carbon, low alloy, and free-cutting steel and ingots.
