The steel mill in Chateauneuf, a suburb
Rive-de-Gier in France, was founded in 1867
by the Marrel brothers and named "Marrel Frères".
Main product were flat irons and armoured plates.
In 1932 a unique combined heavy plate rolling and forging mill was
installed that is still in use today.
Marrel Frères became part of the Creusot
Loire group and eight years later the production of long rolled products
was transfered to St. Etienne and after the bancruptcy of Creusot Loire the
mill became part of USINOR.
In the following years the company changed it's name frequently (Creusot
Loire Industrie, CLI Fafer, Usinor Industeel). Today the site is part of
Industeel producing the largest heavy plate in Europe ranging up to 900mm
(35 inches) in thickness and 80 tons in weight.
