TRIFORCE® open joist will meet or surpass your floor framing requirements for Multi-Family housing. It will provide you with a solid feeling floor system, fire resistance and high levels of durability and reliability.

TRIFORCE® floor system is not afraid of being tested and is designed to withstand harsh weather conditions and even fire. In addition, it provides support for heavy loads over long spans.

The Open Joist TRIFORCE® Features

A few words from our customers

Rob Latham, President
When I first looked at TRIFORCE® I was impressed with the product. Digging deeper, I learned about the automation in their manufacture process, the testing of each piece, the on ground inventory, the technical support, even the literature. The entire package really gave me confidence that this product was something unique. Six years and a lot of hard work later I can honestly say I’ve never been disappointed. I have yet to hear a single complaint from the users and in fact discovered early on TRIFORCE® is actually firmer under foot then other made-to-order plated floor trusses or EWP products.
Mike Meehan, Corporate Advisor
TRIFORCE® has provided a very good solution to many of the problems dealing with floor systems. The performance alone has been well received from our builder customers. The convenience of the open webs has also proven to be very beneficial. And it also provides a better solution to fire code over basement areas. I believe it to be one of the top products we offer.
Brooks Longfellow, Division Manager
TRIFORCE® provides an exceptional floor system solution that improves the performance and design of the home throughout. From the increased strength and minimized deflection to the ability to eliminate bulk heads by running mechanicals through the product, TRIFORCE® has helped us create improved spaces for our clients throughout their home and has aided in the elimination of warranty issues. One of the most underused products in Homebuilding.
Frank Sanford
TRIFORCE® joists are a terrific solution for our customers who want the strength and rigidity of an engineered floor system while meeting fire codes without the onerous burden of having to drywall the entire basement ceiling. Framers love the light weight and workability as well.
Joe Martin, Designer
A great solid floor system. No bounce in floors even at max spans. Really makes it easier to run plumbing, HVAC lines, and electric.
