    The choice of this new steel making process was not an easy decision, though a natural one in retrospect. A small re rolling mill came out into a vastly expanding market. As a re roll mill they had to purchase their steel in a semi finished state from other domestic mills. The strong demand for steel naturally dictated that these mills use their own capacity rather than sell it to a
