Steel grating is not a glamorous product. It’s the industrial flooring, walkways, platforms and stair treads that go into plants, refineries, water treatment works and anywhere else people have to walk over something they shouldn’t fall into. Nucor said Thursday it will spend $59 million adding grating production at Vulcraft Indiana in St. Joe, and the choice of product tells you what the company thinks the next few years of construction demand look like.
What’s being built
A 127,000-square-foot facility on the existing 250-acre site, with groundbreaking planned for the fourth quarter and 20 full-time jobs on top of the 300-plus already there. The plant currently makes open-web steel joists, joist girders and steel decking. Adding grating makes it the fourth Vulcraft location producing the product. The square footage and Q4 timing come from secondary coverage rather than the release itself, so confirm those against the Indiana Economic Development Corporation announcement before relying on them.
Fourth Indiana investment in four years
Nucor has been putting money into Indiana steadily: $290 million to modernize the Crawfordsville sheet mill in 2022, $115 million for a utility infrastructure products plant in 2023, and $28.5 million for an insulated metal panel plant in Waterloo. The company now employs more than 2,600 people across more than a dozen Indiana locations. John Hollatz, EVP of fabricated construction products, tied the grating build to Nucor’s “Grow the Core and Expand Beyond” strategy and thanked Gov. Mike Braun and DeKalb County officials.
Reading the product choice
Joists and deck follow commercial and warehouse construction. Grating follows industrial and infrastructure work: process plants, data center catwalks, water and wastewater facilities, lock and dam machinery platforms. Those are different demand curves, and they have been diverging for two years. Commercial building starts have been soft outside data centers; heavy industrial and public works have not.
Adding grating to a plant that already runs joists lets Nucor sell into both cycles from one fabrication footprint with one sales force. It’s the same logic behind buying downstream fabricators rather than adding melt capacity, which is where most of the company’s recent capital has gone.
The demand side is easy enough to point at. Federal lock replacement work alone, including the Montgomery Locks new chamber on the Ohio River, involves years of platforms, walkways and machinery decks on projects funded through the 2030s. That’s the customer Vulcraft just built a plant for.
