Marcegaglia and Danieli jointly announce the signing of an agreement related to the implementation of a major steelmaking and flat rolling facility investment in Fos‑sur‑Mer, France, with an overall contract value of approximately €450 million including options and spares.

The project, named the Mistral Project, in the range of one billion Euro total CAPEX, represents the most relevant investment in the Marcegaglia’s history, in terms of upstream integration, stabilization of the supply chain, value added expansion and decarbonization; and confirms Danieli’s role as technology partner for large‑scale, sustainable steelmaking investments.

Once completed, the new plant will enable more than 2 million tons of annual production of liquid steel and up to 3 million tons of stainless and carbon steel hot‑rolled coils, covering approximately 35% of Marcegaglia group’s total coil and slab demand, primarily supplying the Italian downstream facilities of Marcegaglia, for different applications.

The investment also reflects a clear commitment to decarbonization: the use of scrap, low carbon HBI and nuclear & renewable energy will enable up to 80% reduction in GHG emissions compared to traditional methods.

The plant will include a modern Electrical Arc Furnace equipped with latest technology and state-of-art features, a single‑strand continuous slab caster producing thick slabs, and a Conventional Hot‑strip mill, ensuring the utmost flexibility by applying different charging mix, stable production performance, consistent product quality, and operational robustness across a wide range of flat steel grades.

The Fos‑sur‑Mer New Complex is engineered in compliance with the most stringent European environmental and safety standards, leveraging advanced automation, optimized resource utilization, and energy‑efficient technologies.

The final investment decision is expected latest by the end of 2026, according to the completion of the permitting process and other conditions currently, in advanced status of negotiation with the relevant French institutions.

The project supports Marcegaglia’s objective of strengthening its competitive positioning in the European flat steel market through sustainable, capital‑efficient growth, while contributing to Danieli’s continued commitment to enabling the steel industry’s green transition.
