Steel shipments measure the tons of steel products a producer delivers during a period.
Companies may report total mill shipments, external shipments, product-level shipments, or a combination of those measures.
Shipments are the volume leg of steel revenue
A simplified steel revenue bridge is:
steel revenue ≈ tons shipped × average selling price per ton
Nucor reported 7.1 million tons of steel-mill shipments in the second quarter of 2026, up 10% year over year. Steel Dynamics reported record first-quarter 2026 steel shipments of 3.6 million tons.
Shipment growth therefore helps investors distinguish higher physical volume from a change in pricing.
Total and external shipments can differ
Vertically integrated producers may transfer steel internally to downstream fabrication or processing operations.
Nucor reported 5.659 million tons of outside steel shipments and 1.441 million tons of inside steel shipments in the second quarter of 2026. Total steel shipments were 7.1 million tons.
That distinction matters because internal tons support downstream operations but are not the same as third-party mill sales.
Shipment mix affects economics
A ton of sheet steel does not have the same economics as a ton of plate, bar, structural steel, or another product.
Nucor separately reports shipment volumes for sheet, bars, structural products, and plate because changes in product mix can affect selling price, mill loading, and profitability.
Investors should therefore ask whether shipment growth came from the same product mix or from a shift toward a different category.
Shipments are not production capacity
A mill can have available capacity that it does not use.
Steel Mill Capacity Utilization connects actual operating volume with the mill network's available capacity. A producer can increase shipments through higher utilization without adding new facilities.

Steel shipments are most useful as the physical-volume leg of steel revenue, interpreted alongside pricing, product mix, utilization, and internal consumption.
