Steel products manufacturer Nucor Corporation plans to expand its operations in St. Joe, Indiana. The $59 million project is expected to create 20 jobs.

The investment at the company’s existing facility will increase manufacturing for steel grating products, expanding Vulcraft’s downstream production capabilities.

“We are pleased to be growing our Vulcraft business in Indiana with this investment to better serve our customers and strengthen our downstream production capabilities, advancing our mission to Grow the Core and Expand Beyond,” said John Hollatz, Executive Vice President of Fabricated Construction Products. “Vulcraft is where Nucor got its start in the steel industry, and it remains an important part of our growth today. We appreciate Governor Braun and state and local DeKalb County leaders for their support as we continue to expand our manufacturing footprint in Indiana.”

Nucor Corporation is a steel and steel products manufacturer that produces sheet, plate, structural steel, bar products, and downstream construction products for automotive, construction, energy, infrastructure, and industrial markets. The company’s Vulcraft division produces steel joists, joist girders and steel decking used primarily in nonresidential construction, including warehouses, data centers, manufacturing facilities, schools and hospitals.

“Indiana manufacturing continues to grow thanks to companies like Vulcraft and its parent company, Nucor Corporation, which are creating jobs across the state,” noted Indiana Secretary of Commerce Chuck Goodrich. “This significant investment in Vulcraft’s operations will continue to propel innovation and excellence in Indiana manufacturing, putting Hoosiers at the forefront of producing critical products used around the country and across the world.”
