Five years later, the two men resigned from the firm when it was taken over by the Republic Iron and Steel Company, and their next project would come in response to major changes that occurred in the community's industrial sector.

Although the company's focus began with sheet and tube, it eventually became one of the nation's most important steel producers with a varied product line.

Due to the imbalance of ironmaking and steelmaking facilities at the two plants, rail shipments of molten iron "hot metal" were sent from Campbell to Brier Hill from 1937 until 1979.

In 1916, Sheet and Tube workers at the East Youngstown plant rioted during a strike over working conditions, which resulted in most of the town's business district being burned to the ground.

In 1952, during the Korean War, President Harry S. Truman attempted to seize American steel mills in order to avert a strike.

The company abruptly closed its Campbell Works and furloughed 5,000 workers on September 19, 1977,[3] a day remembered locally as "Black Monday."

The Brier Hill Works and the company's plants in Indiana were sold to Jones and Laughlin Steel, later acquired by Ling-Temco-Vought (LTV), a conglomerate.

It currently has an online shop where people can purchase apparel and consumer goods, and has a long-term plan of opening up its own factory in the Youngstown area.
