ArcelorMittal France has announced the successful production of the first industrial coil at its new electrical steels production line at the Mardyck site in northern France, marking the start of operations and a key milestone in the commissioning phase. The first coil, produced on March 26, 2026, weighs over 17 metric tons and measures nearly four kilometers in length.
Commissioning phase supports gradual ramp-up
The initial production run allows the company to optimize industrial processes and equipment across preparation, annealing-coating and slitting lines.
This phase is expected to support a gradual ramp-up toward full capacity while ensuring consistent product quality.
Electrical steels key for energy transition
Electrical steels produced at Mardyck, alongside output from ArcelorMittal’s Saint-Chély-d’Apcher facility, play a critical role in the energy transition.
These materials are essential for electric motors and generators used in automotive applications, wind turbines and industrial equipment.
Capacity expansion strengthens European position
The new production line represents a strategic investment aimed at expanding ArcelorMittal’s presence in the electrical steel segment.
Once fully operational, the project is expected to triple the company’s electrical steel production capacity in Europe, reaching approximately 295,000 mt per year, with all production concentrated in France.
According to ArcelorMittal France CEO Bruno Ribo, the next stage will focus on increasing production volumes while maintaining high standards in safety, quality and operational reliability. The development is expected to reinforce France’s industrial ecosystem supporting e-mobility and broader decarbonization efforts.
