The story of the MESSEMPRE millsite goes back to the beginningof the 19th century when ForgesBOUTMY was founded. It wouldseem that the presence of manyforests in this area, along with awater reserve convertible intoelectrical power, was notunconnected with the choiceof this locality.Right from the end of the19th century, MESSEMPRE wasalready widely reputed for itsspeciality: the famous "blue"steel sheets of the Ardennes.However, the destiny of the sitelay elsewhere from the time thelay elsewhere from the time thelay elsewhere from the time theDE WENDEL company acquiredDE WENDEL company acquiredit in 1912 and caused it to takeit in 1912 and caused it to takeon a different industrial course:on a different industrial course:the production of thin steelthe production of thin steelsheets.sheets.Thereafter, industrial develop-Thereafter, industrial develop-ment played its part leading toment played its part leading tothe cold-forming of steel sheets inthe cold-forming of steel sheets in

1954 and, in particular, to thecold-forming of steel sheet pilesas of 1955.Ranked 5th in 1955, MESSEMPREmill is currently the Europeanleader in terms of cold formingsheet piles.Various other changes in shareownership occurred over theyears leading to the setting upof PALFROID in 1995 with thebuying up of 40 % of its sharesby ARBED, whose branch ISPC(International Sheet PilingCompany) was responsible for

sales of the sheet piles produced.Then, in 1997, PALFROIDbecame wholly owned byProfilARBED. Finally, with thecreation of ArcelorMittal, thesales of the cold formed sheetpiles are done by ArcelorMittalCommercial RPS.Ever in search of excellence, thecompany is ISO 9001-certifiedand its products comply withEuropean Standard EN 10249,Parts 1 and 2.
