As steel production increased exponentially, it soon became necessary to merge companies. In 1911, at an extraordinary general corporate meeting of the "Société anonyme des Hauts Fourneaux et Forges de Dudelange", decision was taken to incorporate the "Société anonyme des Mines du Luxembourg et Forges de Sarrebruck" and the "Société en commandite des Forges d'Eich, Le Gallais, Metz et Cie." into the Dudelange company. The new shareholding company, merging the three largest local steel companies, was named ARBED S.A., the acronym for "Aciéries Réunies de Burbach-Eich-Dudelange, Société Anonyme".
