In 1961 a new cogging mill was installed to roll ingots up to 2750 kg in weight compared to only 765 kg before hand using the old mill. After the construction of a brand new 70-ton electric arc furnace in 1972, the old 28” rolling mill was too slow to keep up. So in 1976 it was decided to build a new bar and billet mill that took up a quarter mile of ground space alone.
