The American Iron and Steel Institute (AISI) has added Worthington Steel to its membership roster and elected Geoff Gilmore, president and chief executive officer of the steel processor, to its board of directors.
In Thursday’s announcement, AISI President and CEO Kevin Dempsey noted the robust industry experience Gilmore brings to AISI.
“Worthington Steel and Geoff Gilmore play a major role in the American steel industry. His extensive industry expertise will serve as an asset to the Institute as we navigate the many challenges facing our industry. We look forward to working together on advancing AISI’s mission and member company objectives,” Dempsey said.
AISI Chairman Lourenco Goncalves said he looks forward to working with the executive to advance the steel industry’s interests.
“We are pleased to welcome Geoff Gilmore to the AISI Board. I look forward to our collaboration with Geoff and the Worthington team, united in our mission to advance policy issues on behalf of our industry,” said Goncalves, who is also chairman, president, and CEO of Cleveland-Cliffs.
The Worthington Steel Company began operations in 1955. In 1971, the company became Worthington Industries. And in 2023, Worthington Industries split, and Worthington Steel proceeded in its current iteration. The company is headquartered in Columbus, Ohio.
Clive Grannum, CEO of North American Stainless; Rick Marabito, CEO of Olympic Steel; Guillermo “Willy” Moreno, president of Tenaris USA; and Barry Zekelman, executive chairman and CEO of Zekelman Industries, were elected to the AISI board in June.
