Structural Steel Framing

CanaStruct Inc. is a full-service framing contractor with extensive experience in structural steel framing across the Greater Toronto Area. We work on commercial builds, mixed-use developments, multiplexes, and industrial projects — anywhere that steel frame construction is the right structural solution.

Our steel framing contractor team handles both heavy gauge structural steel and cold-formed light gauge steel stud systems. We understand the engineering requirements behind each system — load paths, connection details, deflection criteria, and fire ratings — and we build to meet them precisely.

We collaborate closely with structural engineers, architects, general contractors, and developers across Toronto, Etobicoke, North York, Scarborough, Mississauga, and surrounding communities. Whether your project calls for steel column erection, wide-span structural steel beams, or a complete metal stud framing system for a commercial interior, CanaStruct delivers the expertise and crew to execute it.

Structural steel framing is the use of steel members — beams, columns, joists, and decking — to form the primary load-bearing skeleton of a building. Unlike wood framing, structural steel can span much greater distances, support significantly higher loads, and perform reliably under fire and seismic conditions that wood cannot match.

The term covers two distinct but related systems. Heavy gauge structural steel refers to hot-rolled steel sections (W-beams, HSS columns, angles, and plates) used for primary structure in commercial, industrial, and multi-storey buildings. Cold-formed steel framing — also called light gauge steel stud framing or metal stud framing — uses thinner, press-formed steel members for walls, partitions, and secondary structure where the load demands are lower but performance, fire ratings, and dimensional stability are still critical.

Related terms you may encounter when researching this type of work include: structural steel contractor, steel erection contractor, steel frame construction, CWB certified steel fabricator, steel beam installation, load-bearing steel framing, and fire-rated steel framing.

Commercial builds — office buildings, retail centres, mixed-use developments, and institutional facilities — frequently rely on structural steel for their primary frame. CanaStruct's steel framing contractors work from engineered structural drawings to erect the steel columns, beams, and secondary framing that form the commercial building's skeleton.

Commercial steel framing demands precision at every connection point. We build to the tolerances and details specified by the structural engineer of record, and we coordinate with other trades so mechanical, electrical, and cladding systems all fit cleanly into the steel frame.

Load-Bearing Steel Framing

When a structure carries significant gravity or lateral loads — from upper floors, roofs, or external forces — the framing system must be engineered and built to transfer those loads reliably down to the foundation. CanaStruct specializes in load-bearing steel framing, including steel column erection, primary beam installation, and moment or shear connections where specified.

We work directly from structural drawings and do not deviate from connection details without engineer sign-off. On load-bearing steel, precision isn't optional — it's the job.

Cold-Formed Steel Framing (Light Gauge Steel Stud Framing)

Cold-formed steel framing — commonly called light gauge steel stud framing or metal stud framing — is the steel counterpart to wood stud framing for walls, partitions, and floor systems in commercial and residential construction. CanaStruct installs light gauge steel systems for exterior and interior walls, curtain wall backup framing, shaft walls, and more.

Light gauge steel studs are dimensionally consistent, moisture-resistant, non-combustible, and compatible with a wide range of fire-rated assembly designs. For commercial interiors and multi-storey residential buildings in Toronto and the GTA, cold-formed steel is often the code-preferred or architect-specified system.

Many commercial, mixed-use, and multi-residential projects in Toronto require fire-rated wall and floor assemblies as mandated by the Ontario Building Code. CanaStruct builds fire-rated steel framing assemblies — including shaft walls, fire separations, and rated corridor framing — using the correct ULC-listed or listed-equivalent assemblies.
Building with fire-rated steel framing requires more than just buying the right studs. Stud spacing, deflection tracks, construction details, and inspection coordination all matter. CanaStruct's framing contractors get the details right.

Wide-Span Structural Steel & Steel Beam Installation
Large open-floor commercial spaces, industrial buildings, and certain residential designs require steel beams capable of spanning significant distances without intermediate supports. CanaStruct coordinates wide-span structural steel installation, including crane-set primary beams, secondary framing, and the connections that tie the whole system together.

We work with structural engineers and fabricators to ensure steel arrives to spec, is handled safely on site, and is erected to the tolerances the design requires.
