The plant in Kraków which was brought to life in 1954, during the first stage of its operations produced merely 1.5 million tonnes of steel per year. Over decades it was extended and modernized, new units like another blast furnace, sheet rolling mill for bodywork sheet production, electrogalvanising line (LEC) and continuous steel casting line were constructed. In January 2003, Krakow’s plant was incorporated into Polskie Huty Stali. Today, it is a flagship plant of ArcelorMittal Poland. The state-of-the-art hot strip mill inaugurated in 2007 still remains the most modern facility and the largest investment of that kind in Europe within the last 20 years.
