The Italian government has filed a damages lawsuit for seven billion euros against steel conglomerate ArcelorMittal. The background involves alleged environmental or contractual violations, the details of which are not yet fully public. The case is relevant to the construction industry, as ArcelorMittal is among the largest suppliers of reinforcing steel in Europe – a material that is indispensable for reinforced concrete structures according to DIN EN 1992 (Eurocode 2). Planners should monitor potential impacts on the availability and price development of concrete steel grades B500A and B500B, should the legal dispute affect the company's production capacities.
