Ancienne usine metallurgique

Since 1874, the site has been home to the Friquet establishments, taken over in 1888 by the Société de Forges de Sedan, then in 1919 by the Aciéries de Longwy after the First World War. A power station was built there on the banks of the Meuse. After the Second World War, the Lorraine-Escault company operated the foundries, rolling mills and a new tube factory (1957). In 1966, Usinor and its subsidiary Vallourec took over the site for the production of large tubes, before the rolling mills were shut down. Vallourec remained active until 1986, then replaced by CEPIA and Ackers (1998), now manufacturing rolling mill cylinders.

The site, connected to the railway network, covers 100 hectares. On the north side (Glaire), the rolling mill halls have a metal structure clad in sheet metal, with skylights for lighting. A water tower and a reinforced concrete maintenance building are added. On the south side (Sedan), 72 m² of production buildings house Ackers, while Avenue de la Marne retains a concierge's lodge decorated with a wrought iron gate with the coat of arms of the Aciéries de Longwy.
