Steel: an exceptional material for your construction projects

Steel has long been the backbone of modern construction. Its unbeatable strength-to-weight ratio, malleability and durability make it the ideal material for designing structures that are reliable, economical and aesthetic.

The advantages of a steel structure

Remarkable strength : supports heavy loads without deforming.

Proven durability : resists weather, corrosion and fire.

Architectural flexibility : enables the creation of bold, custom shapes.

Fast installation : on-site assembly is more efficient than with traditional materials.

Minimal maintenance : galvanized or painted steel retains its properties for several decades.

For these reasons, MetalCo steel structures are preferred in sectors as varied as high-end residential, commercial, industrial and agricultural.

Custom steel structures: the MetalCo specialty

Every project is unique, which is why MetalCo designs custom steel structures that are perfectly adapted to your technical and aesthetic requirements.

Custom design without compromise

Our engineers and technicians use advanced 3D modelling software to visualize the structure before fabrication.

We take into account:

The dynamic and static loads ;

The constraints of the site and the building ;

The regulations (RBQ, NBC, CSA standards) ;

Your aesthetic and functional objectives.

The result: steel structures that are reliable, durable and precise down to the smallest detail.

Design-Build approach for steel structures

The Design-Build method, also known as turnkey, is an integrated approach in which Metalco takes charge of the entire process of delivering a steel structure project: from design to final installation.
Rather than separating design, fabrication and construction among several stakeholders, Design-Build is based on a single partner who coordinates all stages, thereby ensuring consistency, speed and cost-effectiveness.

Our expertise in engineering, technical drawing, fabrication and erection allows us to offer a complete and efficient solution.

We work closely with clients from the very beginning of the project to optimize structural design, reduce production times and control costs.

This approach provides:

Simplified communication with a single point of contact

Reduced unexpected issues and changes during construction

Optimized materials and assembly details

A considerable saving of time and money for the client between design and delivery

Every Design-Build project signed Metalco is designed to offer maximum added value, a superior level of quality and exemplary adherence to deadlines.

Our goal: to make our clients’ lives easier by delivering steel works that combine innovation, precision and efficiency — from the first sketch to the last weld.

Types of steel structures offered

Residential steel structures

Residential projects that combine steel structure and wood framing require specific technical expertise. Integrating steel into a residential build makes it possible to achieve open spaces, longer spans and incomparable strength.

At Metalco, we master this material hybridization perfectly, ensuring precise coordination with engineers, carpenters and architects.

Our teams design, fabricate and install custom steel structures that integrate seamlessly with the wood framing.

The result: homes with bold design, built with rigour, precision and durability.

Industrial and commercial steel structures

Industrial and commercial steel structures require rigorous planning, flawless execution and close coordination between the different trades.
At Metalco, we support our clients (general contractors, engineers and real estate developers) in the design, fabrication and installation of steel structures that meet the highest industry standards.

Our certified teams deliver robust, compliant and durable works that are adapted to the load, safety and performance requirements of commercial and industrial environments.
Thanks to our expertise, we deliver factories, commercial buildings, warehouses, mezzanines, walkways, roof frames and complex structures with millimetre precision and exemplary adherence to deadlines.

At Metalco, every project is handled from A to Z (from 3D modelling to on-site installation) to provide our clients with a turnkey solution that is solid, efficient and durable.

Walkways and structural lintels: balancing performance and aesthetics

Custom steel walkways

We manufacture custom steel walkways that combine strength, functionality and design. They integrate perfectly into industrial buildings, multi-unit residential buildings or public spaces.

FAQ – Everything you need to know about steel structures

1. What is a steel structure?

A steel structure is the metal framework that supports a building, a walkway, a mezzanine or any other work that requires high mechanical strength.
It is made up of beams, columns, bracing and bolted or welded connections.
At Metalco, we design, fabricate and install custom steel structures that comply with engineering plans and Canadian standards.

2. Why choose a steel structure instead of concrete or wood?

3. What certifications are required to work in the steel structure sector?

The steel structure sector in Quebec is highly regulated, and certifications ensure the quality and safety of the work.

Here are the main requirements:

RBQ licence (Régie du bâtiment du Québec)
- Any company that fabricates or installs steel structures must hold an appropriate contractor’s licence, in particular:
  - 5.1 – Steel and metal structure contractor

CWB certification (Canadian Welding Bureau)
- Mandatory for any company that welds structural elements.
- Metalco is CWB certified under CSA W47.1, which guarantees that our welders, our processes and our inspectors meet the highest standards in the industry.

CCQ standards (Commission de la construction du Québec)
- All employees working on job sites must be competent and hold CCQ cards in their respective trades (welder, erector-fitter, etc.).

These certifications ensure that every work fabricated and installed by Metalco is compliant, safe and recognized throughout Quebec.

4. Do you provide design and shop drawings?

Yes. Our technical team produces shop drawings and 3D modelling before fabrication.
