LA STEPHANOISE

What LA STEPHANOISE does

LA STEPHANOISE is a French designer, manufacturer, and installer of equipment for underground mines, quarries, and adjacent heavy industries, headquartered in Saint-Étienne with a registered office in Paris. Founded in 1830 as Etablissements Clair and reorganized in 1912 as S.S.C.M, the company adopted the LA STEPHANOISE brand after World War II and has operated for more than 190 years, making it one of the oldest French mining-equipment OEMs. Since 2005 it has been a subsidiary of RBL-REI within the IWF Group (formerly CMI).

The company sells a portfolio of eight core product lines: underground belt conveyors, chain conveyors, breakers/feeders, gearboxes, longwall shearers, overland (surface) conveyors, and pan conveyors for hot or abrasive materials. Equipment is custom-engineered in 2D (AutoCAD) and 3D (SolidWorks) using proprietary calculation software, and is built in-house in Saint-Étienne, with supplemental fabrication capacity from sister company ALLIA POLAND (added 2021). The product set is certified to ISO 9001 and complies with the ATEX 2014/34/EU directive for explosive atmospheres, and the company has delivered high-capacity installations such as the 3,200 m / 9,000 kW POLYAK EYNEZ underground belt conveyor in Turkey.

LA STEPHANOISE generates revenue through direct enterprise sales of custom-engineered hardware (conveyors, feeders, breakers, gearboxes, shearers) combined with professional services for engineering, design, installation, supervision, and operator training. Projects are quoted on specifications and involve long sales cycles with significant engineering customization. The customer base spans underground coal and lignite mining (AHMSA, COMILOG, SLN, Polyak Eynez, HAMSA, SONICHAR), cement and aggregates (VICAT, HOLCIM, PLACOPLATRE), and metallurgical/aluminum applications (RUSAL, TRIMET), with active references across roughly 30+ countries in Europe, Africa, Latin America, Asia, and North America.
