At Northland Building Supplies, we design and supply high-performance floor systems that meet the structural needs of today’s builders. Whether you’re framing a home, garage, or multi-unit project, we offer precision-engineered joist floor systems and open web floor systems—manufactured in-house or sourced from trusted industry leaders.
Our team works closely with contractors, custom home builders, and developers across Edmonton, delivering complete floor system solutions that are strong, quiet, and ready for installation. With over 50 years of combined design experience and a commitment to local service, we help your builds go up faster, straighter, and more efficiently.
Northland Building Supplies is one of Edmonton’s largest dealers of Weyerhaeuser TJI joist floor systems, known for their strength, reliability, and long-span capability. TJI joists are engineered to resist warping, twisting, and shrinking—common issues that lead to uneven or squeaky floors over time. Their consistent quality and lightweight construction make them faster to install and easier to handle on-site. TJI joists are available in long lengths, reducing the number of joints in your build and creating a smoother, more stable floor system overall.
Northland Building Supplies also manufactures open-web floor systems in our own truss facility, giving you full flexibility and custom options for your floor framing. Designed using advanced Mitek Engineering Software, our open web systems are tailored to each project, not mass-produced or one-size-fits-all. These engineered systems offer wide-open spans and integrated pathways for plumbing, HVAC, and electrical systems, making them a smart choice for complex builds or tight mechanical layouts.
At Northland Building Supplies, we combine expert design, dependable supply, and fast turnaround to give you floor systems that fit your build, not the other way around. Because we handle both joist and open-web solutions, we can recommend a product mix tailored to your specific needs, budget, and construction timeline.
