Founded in 1948, the company Métaux et Produits Industriels (MPI) initially specialized in metal trading. In 2014, the JP Azerad group acquired the CP Inox company, previously owned by Samsung, and renamed it MPI Refendage, based in Lormaison. Two years later, the group expanded its activities by acquiring the site of Mesnil-en-Thelle, formerly owned by the REDE company.

Today, MPI Refendage is a recognized specialist in slitting and shearing metals, boasting two complementary production sites: the Lormaison site, dedicated to varied orders, from prototypes to large series, for a diverse clientele, and the Mesnil-en-Thelle site, focused on large volumes mainly for the construction sector.
