Nucor Vulcraft $59M DeKalb County Expansion, Why Vertical Integration Changes the Procurement Math

On August 13, Nucor announced a $59 million investment to add a steel grating production line at its Vulcraft Indiana facility in St. Joe, DeKalb County. The plant grows to 127,000 square feet, adds 20 new high-wage jobs, and targets completion by end of 2027. That makes Vulcraft Indiana only the second U.S. Vulcraft location producing steel grating.

What the press release doesn't say: this line will draw feedstock from Nucor's own Crawfordsville sheet mill, the facility they spent $290 million modernizing in 2022. Standalone grating producers buy their feedstock on the open market. When hot-rolled prices peak, their margins compress in ways Nucor's internal transfer pricing can buffer. That is a real cost-structure edge in volatile steel markets. Steel Dynamics' fabrication backlog was up nearly 45% year-over-year in Q2. Majestic Steel added decking capacity in June specifically to chase data center and warehouse work. Demand is strong and new capacity is coming online, which is exactly why Nucor is working to lock in regional grating customers now.

If you are procuring grating for industrial construction projects in the Midwest, the question is whether you are still routing through a distributor who will soon be at a lead-time and pricing disadvantage compared to a direct Vulcraft relationship. That conversation belongs at your next procurement cycle, not the one after it.
