From refurbishment to turnkey project
1980 - First plant
Founded by Mr. Jean Tremblay, our core business was the rehabilitation of mechanical equipment in heavy industry. Thanks to our great versatility and expertise in the repair of critical parts, we were able to differentiate ourselves by the speed to deliver customers’ requests.
1986 - New building
Relocated to a brand-new building at 190 rue du Roi with greater production capacity. There have been several phases of expansion since then. Today, the building houses administration, design, cutting and forming equipment, and several assembly and welding stations.
1987 - First new equipment
Aciers Richelieu acquired its first new piece of equipment! Over the years, we have added a 120’ submerged rail-mounted arc, positioners of up to 15 t, hydraulic presses of up to 600 t, a 10’ x 44’ cutting table, a 4-roller rolling machine, a 5-axis horizontal boring machine, and much more.
1988 - Wagon contract
We delivered our first contract for several new railcars. They were destined to ore transport.
1995 - Design Department
A design department was created, now counting 10 draftsmen, project managers and engineers, enabling us to support engineering, as well as design new mechanical parts and equipment.
Actionnariat de Guy et Éric Durand. Après avoir rejoint l'entreprise respectivement en 1987 et 1994 les frères Durand s'associent avec leur oncle M. Jean Tremblay.
2003 - On-site maintenance
An installation team was created to intervene in planned or emergency shutdowns in any type of industrial maintenance work, such as equipment dismantling, maintenance work or welding. Today, we have some forty employees, including welders, industrial mechanics and supervisors.
2006 - 33’ diameter tank
This was Aciers Richelieu’s largest large-scale project, delivered on Marie-Victorin Street in St-Joseph-de-Sorel. This 33’ diameter tank required the repositioning of electrical wires in the road path. Transport took nearly 8 h to cover 1.5 km from our plant on rue Cormier to the customer’s plant.
2011 - New management
Mr. Jean Tremblay passed on the reins of his company Aciers Richelieu to the Durand brothers and their new partner, Patrick Doyon, who joined the company in 2005.
2015 - Acquisition of Usinage St-Laurent
