Nucor's Brandenburg sheet mill hits design capacity after 18-month ramp

Nucor said its Brandenburg plate mill reached its 1.2 million-ton design capacity during the first quarter, closing out an 18-month ramp that had drawn scrutiny from analysts. The Kentucky site began rolling in late 2024 and spent most of last year fine-tuning coil handling and quality systems before hitting full cadence in March.

Plant managers credited steady demand from wind-tower fabricators in Pennsylvania and Virginia, along with a steadier flow of defense orders, for pulling output through the gate. Management told investors on the quarterly call that the mill now ranks among the three most productive plate facilities in North America on a per-hour basis.

The milestone removes one of the last overhangs on Nucor's capital story, with Brandenburg and West Virginia's Apple Grove sheet mill now both producing at plan. Executives said the company will shift its capital program toward downstream services, including a second heat-treat line at Brandenburg expected to come online in 2027.
