From 1880 the works became the property of Gustave Boël. After a failed acquisition by Koninklijke Hoogovens in 1997 the company became a subsidiary of Duferco in 1999, Duferco La Louvière. Blast furnace production was ended by the beginning of the 21st century. A joint venture including the plant was formed with NLMK in 2006, terminated in 2011, with the NLMK and Duferco splitting flat and long product facilities at the plant. Duferco closed their part of the plant in 2013. As of 2016 the flat products line continues operations as NLMK La Louvière. In 1853 Ernest Boucquéau established an iron works in La Louvière, Fonderies et Laminoirs Ernest Boucquéau, situated on the Brussels–Charleroi Canal and in proximity to the Manage to Mons railway line.
