          The 1920s were tough. Brutal, actually.
        
        
          And it would be the foundry that kept
        
        
          the business alive. An ambitious plan for
        
        
          a plate mill was idled until 1928, as were
        
        
          the open hearth furnaces. Two electric
        
        
          furnaces handled all the basic production,
        
        
          except for the odd large sale order when
        
        
          one of the open hearths would be fired
        
        
          up to fulfill the order.
        
        
          Despite the challenges, the company
        
        
          managed to survive. 1928 was the break
        
        
          out year and the company was back to
        
        
          making castings, forgings and plate.
        
        
          Although there was decent demand, the
        
        
          plate mill was operating at less than a
        
        
          quarter of its capacity and the company
        
        
          brass decided to diversify their product.
        
        
          They looked to lighter gauge steels and
        
        
          decided that tin would be the ticket. Up
        
        
          to this point, all tin had been imported
        
        
          from the U.S.
        
        
          The decision set forth a challenge to
        
        
          figure out how to make it with the
        
        
          available equipment. The plate mill could
        
        
          roll an ingot down significantly, but not
        
        
          far enough. The solution? Convert the
        
        
          plate mill to a “Steckel” hot strip mill.
        
        
          The next step was to put a cold reduction
        
        
          process in place. This was accomplished
        
        
          by buying a pilot mill. The first all-
        
        
          Canadian tin was off to market in 1935.
        
        
          The tin did well enough to require a
        
        
          second Cold Mill, which was added in
        
        
          1937.
        
        
          The 24/7 concept came into
        
        
          play at this time as demand for the tin
        
        
          was so high that the two cold mills were
        
        
          absorbing enough tonnage to keep the
        
        
          open hearth and hot mill departments
        
        
          operating 24 hours a day.
        
        
          Dofasco “Tin Girls” are legendary. With
        
        
          swelling ranks during the Second World
        
        
          War, the women were a critical part of
        
        
          the laboratory and inspecting/sorting
        
        
          areas—hundreds of Hamilton’s own
