The Dillinger Group is made up of a series of top-ranking companies which together provide maximum quality and best possible service in the field of heavy plate. This applies both to the work of our integrated iron-and-steel plant, to the production of coke and smelting of iron by Zentralkokerei Saar GmbH and ROGESA Roheisengesellschaft Saar mbH, two subsidiaries owned jointly with Saarstahl AG, and to the production of liquid steel and semi-fabricates. Heavy plate is produced at two locations, Dillinger Hütte, in Dillingen, and Dillinger France, in Dunkirk.

In addition, our trading, flame-cutting and semi-fabrication affiliates provide further downstream services and customised solutions for sales, plus semi-fabrication of heavy plates and other steel products. The 2014 business year also witnessed the inauguration of Steelwind Nordenham GmbH, a 100% Dillinger subsidiary, specialising in the production of monopiles for the offshore wind-energy market.

EUROPIPE GmbH, the world’s leading producer of pipes for oil and natural gas pipelines, with locations in Germany and the USA, was founded in Mülheim an der Ruhr as a 50% subsidiary of Dillinger specifically for the production of pipes from pipe-making plates in 1991.
