Every structure starts with the right bones. Our open web steel joist collection delivers exactly that. Built for strength, speed, and structural integrity, these joists form the backbone of countless commercial, industrial, and multi-use projects. Whether you're framing a flat roof, supporting concrete slab floors, or planning a clean-span warehouse, this is where performance begins.
We don’t just supply open webbed steel joists. We design them to solve real-world problems — limited build time, long spans, tight budgets, evolving floor plans. ILD’s light gauge joists are crafted from galvanized steel and precision-engineered to deliver exceptional support without unnecessary weight or wasted materials. They’re lean, strong, and made to move quickly from order to install.
Standard spans range from 12 to 20 feet, but custom fabrication is always on the table — we can go up to 43 feet if your project calls for it. Use them for floor joists or as part of your open web steel joist roof system. They're easy to integrate with steel deck and joist girders, making them ideal for commercial buildings where flexibility and durability go hand in hand. And because these joists are manufactured in-house, we control quality at every step — from welds to coatings to final delivery.
We used Grade 30, 33, 37, 40, 50 and 80 Steel.
Available Coating: Galvanized G40, G60 and G90. Galvalum is also available for special applications.
Stud Dimensions: our open web joists are made of 89x38mm Joist or 140x41mm joist.
Steel Thicknesses: Gauge 20 to Gauge 16 for 140x41mm Stud and Gauge 22 to Gauge 18 for 89x38mm stud.
This 10" steel joist keeps things lean, both in form and in function. Perfect for smaller spans, tight ceiling spaces, or when you're balancing structural needs with budget constraints. It's compact but doesn’t compromise — built to perform under pressure without adding unnecessary weight.
Its G90 galvanized finish makes it a solid pick for environments where humidity, dust, or minor exposure is a factor. Simple. Dependable. Ideal when you need quick install, fast turnaround, and just enough muscle to support your framing system.
Step up the height, expand your options. The 12" joist opens up more interior flexibility — whether you’re threading mechanical systems, optimizing airflow, or just want more clearance between chords. This joist delivers, without tipping your structural budget.
Use it as a go-to for retail units, commercial interiors, or modular systems where light framing still needs to pull serious weight. The G90 finish holds up well over time, and its balanced proportions make it a favourite for fast-moving construction sites.
This one’s built for that middle ground — strong enough for real loads, light enough for easy handling. The 14" depth offers serious flex for framing long spans or integrating with steel deck systems, especially in commercial settings that demand open, column-free interiors.
Expect clean deflection behavior, easy alignment with composite systems, and a structure that’s ready for the long haul. Whether you're topping an office space or supporting a flat roof over warehouse bays, this joist does the job quietly and reliably.
A real workhorse — this 16" deep joist is engineered for the tough stuff. Heavy service loads, complex MEP integration, long open spans. Whatever your framing challenge is, this joist probably solves it. It’s the backbone of many high-performance roof and floor systems we’ve delivered across Canada.
Its size isn’t just for show — the extra depth means fewer primary framing members, longer spans, and cleaner interior space. G90 galvanization rounds it out with solid protection in all kinds of environments, from dry interiors to exposed, semi-conditioned spaces.
This slightly shorter span (18 ft) with a lighter gauge makes it an ideal pick for smaller builds or cost-sensitive jobs that still demand reliability. The 16" depth provides ample room for services between the chords, while the open web design helps reduce weight and material use without compromising strength.
It’s a go-to for commercial facilities, garages, and specialty joists applications where efficiency and fast install times matter. The G90 galvanized coating further ensures low maintenance in tough conditions.
