The home plant of YS&T was known as the Campbell Works, located in Campbell and Struthers, Ohio. This plant contained four blast furnaces, twelve open hearth furnaces, several blooming mills, two Bessemer converters, a slabbing mill, a butt-weld tube mill, a hot strip mill, seamless tube mills, and and bar mills at the Struthers Works. The Brier Hill Works consisted of two blast furnaces named Grace and Jeannette, twelve open hearth furnaces, a blooming mill, a intermediate blooming mill, a round mill, and plate mills, and an electric-weld tube mill. During much of the Depression, the Brier Hill works was shut down, but it reopened in 1937. Much of the reopened plant's production comprised tube rounds for the Campbell seamless tube mills. 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.
