New Sheet Mill Adds Domestic Steel Supply
Manufacturers buying flat-rolled steel should track coil shipments that begin in December and the planned output ramp in early 2027.
Updated on Nov. 4, 2026 in Manufacturing
Nucor reached commissioning milestones at its new West Virginia sheet mill, where the meltshop produced its first heat in September and the mill began pickling and shipping coils to downstream Nucor divisions in October. The company's new automotive-grade galvanizing line at Berkeley, South Carolina also entered service in October, a development operators in steel-consuming manufacturing should track.
Why it matters
The staged startup shows how a greenfield steel facility is brought online in phases, letting Nucor begin generating shippable product before full capacity is reached. For manufacturers that buy flat-rolled steel, the added domestic sheet and coated-steel supply is a factor in future sourcing and pricing conversations.
Nucor's West Virginia mill is projected to reach 50% capacity utilization by the end of 2027, while its Berkeley galvanizing line targets the same level by mid-2027. The figures are company targets from its third-quarter 2026 earnings call, not reported output.
The players
Nucor Corporation
Nucor is one of the largest steel producers in the United States, operating mini-mill steelmaking facilities and a broad network of steel product divisions serving manufacturing and construction markets.
Stephen D. Laxton
Stephen D. Laxton is Nucor's President and Chief Operating Officer, overseeing the company's operating divisions and facility startups.
The details
The West Virginia facility is moving through staged commissioning, with each stage bringing a part of the mill's manufacturing operations online. Coil pickling and shipment to Nucor's downstream divisions began in October, while the first hot mill, cold mill and construction-grade galvanizing coils are expected in December. Nucor's President and Chief Operating Officer Stephen D. Laxton shared the update during the earnings call.
Timeline
September 2026: West Virginia meltshop produced its first heat.
October 2026: West Virginia mill began pickling and shipping coils; Berkeley automotive-grade galvanizing line entered service.
December 2026: First hot mill, cold mill and construction-grade galvanizing coils are expected.
Early 2027: West Virginia output ramp-up is planned.
Market Landscape
The West Virginia sheet mill extends Nucor's electric arc furnace mini-mill approach into flat-rolled steel production at a new domestic site. The Berkeley galvanizing line adds coated-steel capacity in South Carolina, giving the company additional finishing capacity for automotive and construction customers.
Manufacturers that buy flat-rolled and coated steel should monitor when the West Virginia mill begins shipping coils, since added domestic supply could affect lead times and pricing in future quotes. Procurement teams may want to revisit domestic supplier options as new capacity comes online through 2027.
The takeaway
Greenfield steel capacity typically arrives in stages, so operators should watch for the first shipped coils and the output ramp rather than the initial commissioning announcements. Procurement managers should track the December coil timeline and the early-2027 ramp when reviewing domestic steel sourcing options.
What happens next
Nucor expects the first hot mill, cold mill and construction-grade galvanizing coils from the West Virginia facility in December, followed by an output ramp-up in early 2027.
