ArcelorMittal Restarts Fos-sur-Mer Steelworks After October Fire

Management links the site’s long-term upgrades to EU market protections.

Overview

  • The company told roughly 2,400 employees the restart would occur on December 23 after an October 8 blaze damaged conveyor structures and an electrical station without injuries.
  • Blast furnace No. 2 was brought back online in mid-December, and the first slab was produced at 3:24 a.m. on December 22 for a Greek customer as rolling operations resumed.
  • Deliveries to Mediterranean clients are restarting, with production moving from slabs to rolled coils.
  • Blast furnace No. 1 remains out of service for renovation and is slated for a 2026 relaunch to take over from No. 2.
  • Leaders are considering a €750 million electric‑arc furnace to decarbonize the site, contingent on the EU steel plan, while unions report heavy losses running to several hundred million euros.
