ArcelorMittal steel brings Mont Saint-Michel back to life

ArcelorMittal steel has ensured the Mont Saint-Michel – one of France’s best-loved visitor sites – is an island once again.

Located off France’s north-western coast, the UNESCO-listed tourist hot spot has been moving closer to the mainland due to silt build-ups caused by canal work at the Couesnon River.

But thanks to the strong properties of steel from ArcelorMittal subsidiary Industeel, the Mont Saint-Michel has become an island again – work which French president François Hollande recognised during his visit to the island last month.

Freeing the Mont Saint-Michel from the sand was a major challenge. The main objective was to build a dam on the Couesnon River to flush away sediment with the flow of water. 

The dam valves were built with Ur® 2205 Duplex steel from Industeel – a wholly-owned ArcelorMittal subsidiary specialised in the production of hot-rolled steel plates, including stainless steel plates for use in highly specialised industries. Steel for the valves was produced at an Industeel site at Le Creusot. 

Jean-Christophe Gagnepain, stainless steel commercial manager, ArcelorMittal, said: “Duplex stainless steels are well-known around the world, and have been used for more than 20 years to build seawater desalination plants due to its very strong anti-corrosion properties. With such advantages, Duplex steel plates were the ideal product for the valve system of the dam”.

Vincent Pairet, CEO of Industeel, added: “This project will bring long-term positive results to the Mont Saint-Michel. ArcelorMittal is very proud to once again see Industeel involved in the preservation of a treasured historical site”.
