A little history…
Above all, a human adventure

In 1996, Eric PERRIN wrote this book in which he retraced the industrial history of the Saint-Chamond site. He dedicates it to his father and grandfather.
He also dedicates it to me and writes…in the hope of an industrial future in Saint-Chamond… Perhaps without knowing it, did he charge me with a mission? Personally, I think that nothing is irreversible and that we can always hope...for that, we must try!

On October 17, 2012, by the will of a few people, the company CLESID LORBER (former flagship of French industry) was reborn…
This one, born in the Loire, specialized in converters, dedusting systems, continuous casting, electric arc furnaces but also in processing and finishing lines for flat products, disappeared in 1982 following the merger with SECIM, CLE and Delattre Levivier
Today, CLESID LORBER is returning to 53 rue Sibert on the historic site of Saint Chamond, renamed Novaciéries.
The skills of the men and women who made CLESID LORBER have been perpetuated through the companies that have succeeded this merger rich in this heritage, some are now back to continue this industrial adventure, which began in the middle of the 19th century.
The desire to establish the company in the French industrial landscape over the long term, combined with strategic initiatives aimed at strengthening our structure and positioning us on large-scale projects, led in 2025 to the acquisition of a stake in the SDIH group, chaired by Mr Guillaume Pasquier. To mark this significant transformation, CLESID Lorber is changing its name to : ArcInnov Technologies.

Director’s word
By creating this company and using the name of CLESID LORBER, I wanted to pay tribute to all these French engineers who were at the origin of so many technological innovations, inventions, and developments in this very particular field of steelmaking.
Through their intellectual and often personal investment, they ensured that French industry was, at some point, recognized worldwide.
They had the entrepreneurial spirit and the concern that their knowledge be at the service of progress by relying on networks of strong skills and by not hesitating themselves, to transfer skills to their collaborators.
I personally benefited from it and today, my only ambition is to perpetuate this heritage and to enhance it.
The CLESID LORBER team is young and with the skills it gathers and develops, full of future!
The story of CLESID LORBER began in the 19th century and thanks to us, it continues today.
