A Legacy of Metallurgical Excellence Since 1872
Manoir France is a historic metallurgical company rooted in more than a century of industrial know-how, with origins dating back to 1872 when its first steel foundry was established in Pompey as “Les Acieries de Pompey”, France. During the first WWI, the company moved in 1917 to a more secure place, away from the war front, along the river Seine in Le Manoir sur Seine, Normandy.
Investment in future growth
Manoir France entered a new chapter in 2024
Over the decades, the company evolved from a regional steelwork supplying defence, rail and shipbuilding into a leading specialist in high-performance metallurgy, investing in electric-arc furnaces, advanced alloys, and cutting-edge casting techniques.
After a challenging period, Manoir France entered a new chapter in 2024 when it was acquired by Paralloy Group, strengthening its foundation for long-term stability and growth. Today, the company continues to carry forward its legacy in advanced metal processing, combining its century-old expertise with modern investment and a forward-looking vision.
