1920: The company sets up shop at St Just, in the Loire, a town now connected with St Rambert, to develop a wireworks business that he now focuses completely on wire products.

1960: The entity starts manufacturing a new product: welded mesh for concrete reinforcement. GAPIAND establishments are renamed Tréfileries du Sud Est (Wireworks of the South East, T.S.E)

1979: High-adherence wire for mesh requires new machines, which leads T.S.E. to build a 3,300 m2 building for wire drawing, 150m away from the existing buildings. This will become the foundation for the current site. 

1984: Faced with financial difficulties in the midst of the steel crisis, T.S.E. files for bankruptcy.

1986: After two years of administration by a trustee, T.S.E. is acquired by SACILOR. The building which was built in 1979 will be used as the shell for a production line to manufacture welded mesh. The gradual shutdown of the wireworks had begun.

1990: The legal entity T.S.E. no longer exists, the site is named ACOR St. Just, whose parent company is UNIMETAL. 

1992: The wireworks are shut down, ACOR St Just produces only welded lattice. 

1993: After the break-up of UNIMETAL, a new entity was created under the name SAM, consolidating concrete reinforcing steel operations.

1995: USINOR sells SAM and its subsidiaries (including ACOR) to the British group ASW (Allied Steel and Wire). In addition to manufacturing standard welded mesh, a special mesh business (so-called technical mesh) is developed, which only lasted two years.
