Our story
Built on Absolute Mechanical Expertise
Founded in 1985 by Louis-Charles Rondeau, Usinage Supérieur began with a singular focus: mechanical expertise and an uncompromising dedication to precision. From a small rented shop with a handful of machines, we grew the way a heavy machine shop should—by proving our capabilities one complex part at a time.
As our clients' projects grew in scale and complexity, so did our infrastructure. We aggressively transitioned into advanced CNC technologies, expanding our physical footprint to accommodate 20-ton overhead bridge cranes and massive machining envelopes. We didn't just add floor space; we purposely built a facility engineered to handle the colossal industrial fabrications that other shops had to turn away.
Over the decades, these strategic acquisitions and the construction of our dedicated Sainte-Catherine plant have cemented our place as an industry leader. Yet, even with our state-of-the-art equipment, our greatest asset remains the unmatched skill of our machinists. The determination of our founder continues to drive our culture today, securing the trust of our most demanding industrial partners.
We do not just machine parts; we build long-term partnerships based on reliability and technical excellence.
Mission and vision
What We Are Here To Do
Two statements we hold ourselves to. Both are short on purpose — a mission nobody on the floor can repeat is not a mission.
Our mission
Provide absolute industrial reliability.
Our mission is to offer unmatched value to our customers by providing efficient, reliable, and complete heavy industrial machining and fabrication services. We exist so that an engineer can release a drawing and trust it will be executed flawlessly.
- Deliver turnkey solutions backed by a personalized approach.
- Hold the exact tolerances the drawing demands.
- Put the inspection record in the box, every single lot.
Our vision
Your Projects. Our Projects.
We are building the premier machining partnership in Quebec. By combining our state-of-the-art machine park with a highly collaborative workforce, we tackle the industry's heaviest and most complex challenges.
- Treat every client's project with the same care as our own.
- Invest heavily in our people and our CNC technology.
- Push the boundaries of heavy turnkey manufacturing.
What we hold to
Our Core Principles
Values are only worth listing if they actively guide how we operate on the shop floor. These four principles define our corporate culture, drive our decision-making, and ensure we consistently deliver absolute precision to our industrial partners.
Absolute Reliability
We cultivate a corporate culture that requires us to live up to our commitments. Customer satisfaction is central, and we maintain partnerships based on deep trust, integrity, transparency, and respect.
Strategic Collaboration
Recognizing the immense value of bringing together diverse knowledge and expertise, we create an environment that promotes success. Whether among colleagues, customers, or our partners at Thermofin, we firmly believe that together, we accomplish more.
Continuous Improvement
By continually working to optimize our services and processes, we remain among the elite machining companies in Quebec. Ongoing investments in our recent machine park keep our team motivated, efficient, and ready for the future.
Turnkey Accountability
We take complete ownership of your project from raw steel to final assembly. By integrating our heavy industrial machining capacity with advanced fabrication, we eliminate supply chain blind spots and deliver mission-critical components without excuses.
OUR PEOPLE
Tier-1 Capacity. True Human Partnerships
At Usinage Supérieur, we possess the institutional scale to supply North America's largest transit and energy networks. But behind every massive CNC envelope and strict ISO certification is a team that values genuine human connection. We believe that heavy manufacturing isn't just about cutting metal; it's about building enduring, trust-based relationships with the engineers and procurement teams who rely on us.
Our production floor is driven by a tight-knit family of highly skilled machinists, CWB-certified welders, and quality inspectors. This collective dedication to craftsmanship—reflected by the men and women who physically build your parts—ensures that every colossal component is treated with personal accountability and pride.
At the management and intake level, we intentionally strip away rigid corporate red tape. We pride ourselves on proximity, extreme responsiveness, and actively listening to your project's unique challenges. Whether we are navigating a critical supply timeline for major transit authorities like STM and VIA Rail, or problem-solving with leading OEMs, we act as an accessible, highly collaborative extension of your own team.
We deliver the physical capacity, traceability, and certified quality of a major industrial corporation, combined with the agility, warmth, and collaborative spirit of a trusted partner. Your success is personal to us.

A HISTORICAL SYNERGY
Two Sister Companies. One Shared Vision
Usinage Supérieur and Thermofin are more than just business partners; we are sister companies that have grown and evolved side by side. Owned by one of Thermofin’s co-founders, Usinage Supérieur has always shared the same industrial DNA, the same rigorous quality standards, and the same drive to push the boundaries of heavy manufacturing.
For decades, we have worked hand in hand. Our capacity to machine massive, highly complex components was developed in perfect harmony with Thermofin’s world-class expertise in custom heat exchangers. This mutual, organic growth has allowed both companies to optimize our internal processes, share core values of integrity and responsibility, and consistently deliver fast, reliable results to our clients.
Today, this historical synergy is stronger than ever. By fully integrating our massive CNC machining operations with Thermofin’s large-scale fabrication and engineering power, we offer our clients a true end-to-end manufacturing solution. From raw steel processing to the final turnkey assembly, we are combining our unified know-how to reach new heights together.
We Do Not Just Machine Parts; Together With Thermofin, We Build Long-Term Partnerships Based On Absolute Reliability And Technical Excellence.
