Steel metal spread is the difference between a steel producer's realized selling price and the cost of key metallic raw materials used to make the steel.
For electric-arc-furnace producers, those inputs commonly include ferrous scrap and scrap substitutes.
A simplified form is:
metal spread ≈ steel selling price per ton - metallic input cost per ton
The exact calculation is issuer-defined and may not use perfectly matching tonnage bases.
Why metal spread matters
Steel prices and scrap costs can move independently.
Nucor reported that higher metal margins were the main driver of stronger steel-mill gross margins in the second quarter of 2026. Steel Dynamics likewise said first-quarter 2026 steel earnings benefited from metal-spread expansion because steel pricing increased more than ferrous scrap costs.
That makes the spread a useful bridge between revenue pricing and mill profitability.
A simple example
Suppose realized steel pricing rises from $1,000 to $1,100 per ton while metallic input cost rises from $400 to $430.
The simplified spread moves from:
$1,000 - $400 = $600
to:
$1,100 - $430 = $670
The spread widens by $70 per ton even though input costs increased.
Metal spread is not gross margin
Metallic raw materials are only part of steel production cost.
Labor, electricity, natural gas, alloys, electrodes, maintenance, depreciation, freight, and other manufacturing costs still matter.
A wider metal spread can therefore coexist with weak overall profitability if other costs rise sharply or utilization deteriorates.
Company definitions can differ
Nucor defines metal margin as the difference between steel selling price and the cost of scrap and scrap substitutes.
Steel Dynamics defines steel metal spread using average steel-mill selling prices and ferrous scrap consumed in its steel mills.
Those definitions are economically related but should not be assumed to be numerically interchangeable.

Steel metal spread is most useful as a raw-material margin bridge, not as a substitute for gross margin or operating margin.
