Nucor Corporation will invest $59 million to expand its Vulcraft Indiana manufacturing facility in St. Joe, Indiana, adding capabilities to produce steel grating products. The investment is expected to create 20 new full time jobs, adding to the more than 300 teammates currently employed at the facility.
“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.
This marks Nucor’s fourth major investment in Indiana in recent years. In 2022, the company announced a $290 million investment to modernize its sheet mill operations in Crawfordsville. The following year, Nucor announced plans to build a $115 million utility infrastructure production facility nearby. The company also invested $28.5 million to build an insulated metal panel production facility in Waterloo, adjacent to its existing Nucor Building Systems Indiana campus. That facility began operations in 2021.
Together, these investments have created approximately 300 new Nucor jobs in Indiana. Today, Nucor employs more than 2,600 teammates at more than a dozen locations across the state.
Nucor acquired Vulcraft in 1962, marking the company’s entrance into the steel industry. From a single production facility in South Carolina, Nucor expanded the Vulcraft business and ultimately made the decision to begin producing its own steel. Vulcraft Indiana opened in 1972 as Nucor’s fifth Vulcraft facility and today is one of nine Vulcraft facilities operating across North America.
Vulcraft is the nation’s leading producer of open-web steel joists, joist girders and steel decking, which are used primarily in nonresidential construction. These products serve as structural support systems for roofs and floors in warehouses, data centers, manufacturing facilities, retail stores, shopping centers, schools and hospitals as well as in some multi-story residential buildings. Vulcraft has an annual joist and deck production capacity of approximately 1.2 million tons.
