Steel Beams Toronto

Professional Steel Beams in the GTA

Last updated: March 6, 2026

Konstruction Group fabricates and installs steel beams for residential and commercial construction throughout Toronto and the GTA. Every custom home and multiplex project we frame includes steel beams - they're essential for open floor plans, load-bearing wall removals, and structural support. We handle the complete process: fabrication in our CWB-certified shop, delivery, and professional installation by certified welders. Single-source accountability means your beam work coordinates seamlessly with our framing, insulation, and drywall services.

Steel Beam Services

• Load-Bearing Wall Removal – Steel beams to replace load-bearing walls and open floor plans safely
• New Construction Beams – Structural beams for new builds, additions, and commercial projects
• Floor Support Beams – Main beams and girders supporting floor joists and loads
• Beam Reinforcement – Adding steel beams to strengthen existing structures
• Header Beams – Steel headers for large window and door openings
• Cantilever Beams – Beams for balconies, overhangs, and cantilever construction

Types & Sizes of Steel Beams

• W-Shape (Wide Flange) – Most common structural beam - efficient for long spans and heavy loads
• S-Shape (I-Beam) – Traditional I-beam profile used in older construction and specific applications
• HSS (Hollow Structural Section) – Square and rectangular tube sections for exposed applications and posts
• Steel Channels – C-shaped sections for headers, lintels, and lighter applications
• Built-Up Beams – Custom fabricated beams for extreme loads or special requirements

Structural Steel Beams & Support Beams

Every steel beam we install serves a structural purpose — carrying loads from above and transferring them to columns or bearing walls below. Common residential applications include support beams for load-bearing wall removal, floor system beams spanning basements and garages, and header beams over wide window and door openings. We size beams based on your engineer's specifications, considering span length, load requirements, and connection details. Our steel beams are fabricated in-house with welded end plates and stiffeners as specified.

Professional Installation Process

Steel beam installation requires careful engineering and execution. We begin with temporary shoring to support loads during installation. The beam is positioned precisely using lifting equipment, then permanently connected to supporting columns or walls with welded or bolted connections. All work follows the structural engineer's specifications and Ontario Building Code requirements.

Steel Beams in Every Custom Home & Multiplex

Nearly every custom home and multiplex we frame requires steel beams. Open-concept main floors need beams where load-bearing walls would otherwise divide the space. Second-storey additions require beams to carry new loads. Multiplexes use steel beams for large openings, floor support, and structural transitions - followed by soundproofing and fireproofing to meet code requirements. Because we handle both framing and steel, coordination is seamless - our crews install the beams and frame around them in one continuous operation.

Engineering Coordination

Steel beam sizing must be determined by a structural engineer who calculates loads, spans, and connection requirements. We work directly with engineers to understand specifications and ensure proper installation. For projects without existing engineering, we can recommend structural engineers familiar with residential and commercial construction.
