On 1 October 2026 EUROMETAL reprinted a Platts report, part of S&P Global Energy, on a one-week stop at ArcelorMittal’s Gijón long-products works in Asturias. A company spokesperson told Platts on 29 September that the halt began on 28 September and would run through 3 October, citing the steel-wire order book. The plant has already taken several short stops of about a week during 2026.

SteelOrbis, citing Spanish media the same day, said the company was aligning output with demand that has not recovered after the European Union’s new steel trade-defence measures took effect on 1 July. The weak book is most visible in wire rod. The wire-rod mill, the rail mill and the Gijón steelworks sit in ArcelorMittal’s Long Products division in Asturias. GMK Center, reporting El Comercio on 30 September, put the affected headcount at about 200 site workers plus subcontractors and said the order book was insufficient.

EUROMETAL put the site at 1.1 million tonnes a year. One of its two blast furnaces, Furnace B, was offline for about four months in the first half of 2026 after a production issue that followed 2025 maintenance. A conveyor-belt fire on the night of 28 September, reported by SteelOrbis from local media, was extinguished the same night. The company did not give that fire as the reason for the production stop.

Energy costs sit on a different clock

Unesid, the Spanish steel association, published a 22 September note that SteelOrbis summarised on 25 September. The association’s provisional estimate puts extra energy costs for Spanish steel at about €658 million between March and December 2026, of which about €452 million falls in September to December against €206 million through August. Electricity accounts for about €403 million of that extra bill and gas for about €255 million.

Unesid said the July electricity-market average reached €104.75 per megawatt-hour, 50.5 percent above June, and that MIBGAS gas averaged about €55.5 per megawatt-hour, 23.5 percent higher. Its fourth-quarter outlook is about €143 per megawatt-hour for power and about €76 for gas. Grid-balancing services add about €20 per megawatt-hour in 2026 on the association’s headline figure, or €21.60 per megawatt-hour for consumers in the fourth-quarter arithmetic. Unesid said companies are already stopping in the most expensive electricity hours, and that the practice can spread if those levels hold.

The association asked the Spanish government for an immediate energy plan through 2027. The main requests are to raise 2026 compensation for indirect CO2 costs to at least €1 billion, the ceiling under EU rules, and to make the 80 percent cut in electricity grid charges for electro-intensive industry permanent. About 70 percent of Spanish steel output is exported, Unesid said, and about two-thirds of those tonnes go to other EU countries. In 2025 the industry produced 11.8 million tonnes and exported about 8 million. Unesid also said Spanish steel exports to the Near and Middle East fell from a 2025 monthly average of 8,470 tonnes to about 3,154 tonnes in March to June 2026.

Sources at ArcelorMittal told El Comercio, as carried by GMK Center, that this Gijón stop was not taken for energy costs. The same sources said the energy trend could still make production unsustainable if it continues. For a yard the distinction is operational. A wire-rod restock pause lasts days. A peak-hour power stop can repeat through the fourth quarter at more than one Spanish melt shop.

The EAF still changes the charge

On the same 29 September call, ArcelorMittal confirmed to Platts that it still expects a new 1.1 million-tonne-a-year electric-arc furnace at Gijón in 2026. The furnace will feed the two long-products rolling mills and will use direct-reduced iron, hot-briquetted iron and scrap. Company material already on the public record puts the investment at €213 million and the products as rail and wire rod. That start is later than the original first-quarter 2026 first-heat target.

This Gijón unit is a different project from the 2 million-tonne Dunkirk furnace listed in GMK Center’s EAF demand note to Platts. The Spanish furnace is built into an existing longs shop that already rolls rail and wire rod. Once it runs, the charge at Gijón moves from blast-furnace hot metal toward a scrap-plus-DRI/HBI mix. Unesid says Spanish steel already remelts about 9.3 million tonnes of scrap a year. The practical change for a seller is the specification: prepared ferrous with a residual and size ticket that a rail or wire-rod melt can use.

CBAM prices imported steel products, not scrap under CN 7204. The industrial effect in Asturias is a scrap-fed longs furnace if the book and the power price let it run.

Who it affects among yards, traders, mills and processors

An Iberian yard that sells HMS, shredded or new-production cuttings into Asturias should treat 28 September to 3 October as a wire-rod offtake gap, not a closed mill. Delivery weeks that sat inside the stop will slip. The rail mill is the same site. A rail programme does not move on the same rhythm as wire rod.

Other Spanish electric-arc works face the Unesid power bill even when Gijón is melting. Peak-hour stops cut the daily melt without a published halt. A trader booking domestic Spain should ask whether the buyer is taking metal this week or parking it. Freight and collection costs still sit on a delivered tonne when the furnace is idle for a shift.

Export sellers who used Spanish surplus to cover Turkey or other seaborne buyers should not read this stop as extra export tonnes. A one-week longs pause does not refill a deep-sea stem. Scrap metal prices on a Spanish domestic lot remain a delivered mill number, not a CFR Iskenderun number.

Processors preparing furnace feed for rail or wire rod should keep copper residuals and size on the ticket. A hybrid EAF that also takes DRI or HBI still rejects dirt and copper that a rebar melt might dilute.

How to name the lot

Name the grade the mill already buys: HMS 1&2 80/20, shredded, or new-production cuttings if that is what you have. Spanish and other EU works often write E40 for fragmentiser steel and E3 or E1 for heavier melting steel. If the buyer works in ISRI language, write HMS or shredded 211 and say so. Do not invent a copper cap or a thickness you have not measured.

State tonnes, packing, city or load point, and whether the sale is ex-works, delivered mill, FOB or CFR. If the parcel was booked around the Gijón stop, say whether it is still waiting or has already moved. Do not write a carbon claim on the parcel.

Verified companies can list on live lots or post a wanted enquiry. Request access if you have ferrous feed for Iberian longs or a mill programme to cover.
