Open Web Steel Joist Service
Professional Open Web Steel Joist (OWSJ) Services Across Ontario
At Peel Welding & Fabrication, we specialize in the installation, fabrication, reinforcement, and repair of Open Web Steel Joists (OWSJs) for commercial, industrial, and multi-unit residential projects across Ontario. Based in Mississauga, we serve the entire GTA including Brampton, Toronto, Vaughan, Oakville, Markham, and surrounding cities.
OWSJs are the backbone of modern commercial and industrial floor and roof systems. Their lightweight truss-like design delivers exceptional load-bearing strength across both short and long spans, making them the preferred structural choice for warehouses, retail centres, office buildings, schools, and manufacturing facilities throughout Ontario.
Whether your project demands new joist installation, OWSJ reinforcement to increase load capacity, or emergency field repairs, our CWB-certified welding team brings the expertise, equipment, and commitment to safety your structure requires.
Why Choose Open Web Steel Joists?
Open Web Steel Joists offer a unique combination of structural efficiency and practical advantages that make them the go-to choice for contractors, engineers, and developers across Ontario:
- Structural Strength: OWSJs are engineered truss-like components capable of supporting heavy loads over both short and long spans, meeting National Building Code of Canada (NBCC) and CAN/CSA S-16 requirements.
- Lightweight Design: Despite their impressive strength-to-weight ratio, OWSJs significantly reduce the dead load on supporting structures compared to solid steel beams, lowering overall material costs.
- Service Integration: The open web configuration allows for easy routing of mechanical, electrical, and plumbing (MEP) systems through the joist cavities — eliminating the need for additional drop ceilings and reducing building height requirements.
- Speed of Construction: Prefabricated and ready to install, OWSJs speed up framing timelines on commercial and industrial projects across the GTA and Ontario.
- Cost-Effective Solution: Compared to solid steel alternatives, OWSJs offer a more economical structural system for floor and roof assemblies in non-residential construction.
- Versatility: Suitable for warehouses, big-box retail, schools, office buildings, manufacturing plants, and multi-unit residential mid-rise construction throughout Ontario.

OWSJ Repair & Field Welding
Damaged or undersized joists compromise structural integrity. Our team provides on-site repair and field welding for OWSJs in active commercial buildings, warehouses, and construction sites — minimizing downtime and disruption to your operations throughout the GTA.
OWSJ Inspection & Assessment
Before reinforcement or replacement, our certified welders conduct thorough on-site assessments of existing joist conditions, identifying signs of corrosion, overloading, improper modification, or inadequate connections. We provide detailed findings to support your structural engineer's decisions.
Joist Girder & Steel Deck Integration
We install and weld joist girders the primary framing members that carry OWSJ loads to supporting columns as well as steel deck panels. This integrated approach ensures structural coordination and a faster, cleaner construction timeline for your Ontario project.
