Cockerill-Sambre was a group of Belgian steel manufacturers headquartered in Seraing, on the river Meuse, and in Charleroi, on the river Sambre. The Cockerill-Sambre group was formed in 1981 by the merger of two Belgian steel groups – SA Cockerill-Ougrée based at Seraing in the province of Liège, and Hainaut-Sambre based at Charleroi in the province of Hainaut – both being the result of post-World War II consolidations of the Belgian steel industry.
The company inherited a steel industry with significant debts and production overcapacity based on blast furnace production rather than electric furnace recycling, with numerous factory sites in constrained city locations, and adversely affected by competition in the export market from new steel-producing countries (such as South Korea and Brasil). The need to streamline was complicated by regional dependence on employment in the steel industry.
It was merged into Usinor in 1999, and after 2002 was part of the Arcelor group. As of 2010, the bulk of the group is part of the ArcelorMittal multinational steel group, where it is known as ArcelorMittal Liège.
