As GMK Center reported earlier, Zaporizhstal increased its output by 50.6% year-on-year – to 7.24 million tons in 2023. In particular, the plant produced:

  • pig iron – 2.72 million tons (+35.3% y/y);
  • steel – 2.47 million tons (+65.4%);
  • rolled goods – 2.05 million tons (+57.2%).

Enemy shelling and destruction, interruptions in the supply of raw materials and energy, and disruption of logistics routes due to the blockade of seaports led to a decline in Zaporizhstal’s production performance compared to pre-war levels. In particular, in 2021, the plant produced 4.5 million tons of iron, 3.8 million tons of steel and 3.2 million tons of rolled products. In 2023, the plant operated at an average of 70% of its capacity.
