Nucor Advances West Virginia Sheet Mill Startup
Nucor's new West Virginia sheet mill has moved through several commissioning milestones, with the company sharing the update on its third-quarter 2026 earnings call.
Updated on Nov. 4, 2026 in Manufacturing
Nucor's West Virginia meltshop produced its first heat in September, and the mill began pickling coils and shipping them to downstream Nucor divisions in October. The company also reported that its automotive-grade galvanizing line at Berkeley, South Carolina entered service in October.
Why it matters
The West Virginia facility is progressing through staged commissioning, which brings its manufacturing operations online in phases. The milestones show the mill moving from initial steelmaking toward finished product shipments.
Nucor is targeting 50% capacity utilisation at its West Virginia sheet mill by the end of 2027 and 50% utilisation of its Berkeley galvanizing line by mid-2027. Current output volumes at both facilities were not disclosed on the call.

Timeline
September 2026: West Virginia meltshop produces its first heat.
October 2026: West Virginia mill begins pickling and shipping coils; Berkeley automotive-grade galvanizing line enters service.
December 2026: First hot mill, cold mill and construction-grade galvanizing coils expected.
Early 2027: West Virginia output ramp-up begins.
Market Landscape
Nucor's West Virginia greenfield sheet mill extends the electric arc furnace mini-mill model that has reshaped U.S. steel production into flat-rolled sheet products. The expansion adds capacity in a segment where the company competes against integrated steelmakers and other domestic producers.
Customers who buy sheet steel for construction and automotive parts may see product availability from the new mill as output ramps up in early 2027. The company has not announced specific pricing or product-tier changes tied to these milestones.
The takeaway
Commissioning milestones at a new steel facility often reveal progress well before full output, so the pace of ramp-up is the key signal to watch. Readers tracking steel supply should follow Nucor's updates on utilisation targets through 2027.
