STS, which was started in 1984 by Arnold Erwin and his father, will continue to operate under its own brand at its Hixson facility. The privately-held company has about 90 employees at its facilities in Chattanooga and Gallatin, Tenn., and serves a diversified account base with specialization in bar and plate processing, with grinding capabilities. Its customer base includes machine, tool and die shops, energy providers, automotive manufacturers, appliance manufacturers and aerospace parts manufacturers.

“STS brings extensive bar and plate processing capabilities to Ryerson, consistent with our focus on long products and value-added services,” Ryerson CEO Eddie Lehner said in a statement. “Moreover, like our acquisition of Fay Industries announced in January 2015, we are joined by a company in STS that creates exceptional customer experiences in the southern U.S. market.”

Ryerson operates a Chattanooga facility on Polymer Drive in Chattanooga – one of more than 100 locations operated by Ryerson in the United States, Mexico, Canada, China and Brazil. Founded in 1842, Ryerson has about 4,000 employees.

“Joining Ryerson enables Southern Tool Steel to capitalize on our growth opportunities and fulfill our primary objective, which is to solve problems and provide superior service to customers,” said Erwin, chief executive officer of STS.
