Builders, forget inefficient steel-plated floor trusses.

Plan changes, late shipments, jobsite safety issues…

Are you tired of the daily challenges you have to face?

Plan changes, jobsite safety issues, tight deadlines and late shipments. More than one of these issues often arise when steel-plated trusses are specified for floor framing.



Meet an all-wood finger-jointed joist that cuts your labor costs dramatically.

Not adjustable at the jobsite.

If plans change or a foundation is out-of-square, plated trusses cannot be altered to fit the new circumstances. New trusses must be manufactured with significant wait times, especially during peak building seasons.

Trim a joist on the spot.

Trim a joist to fit and continue framing. TRIFORCE® open joists are shipped from stock so order turnaround is measured in days rather than weeks.

Steel plates have several drawbacks.

Plated floor trusses are very heavy, present a handling danger because of sharp plate edges, and plates often interfere with the installation of mechanicals. Steel is also a non-renewable resource manufactured with great energy consumption.

All-wood finger-joined floor joist.

There are no metal plates to add weight, injure framers or hinder the installation of electrical, plumbing or HVAC systems.

Floor trusses are not fire-code friendly.

In jurisdictions where recent versions of the IRC fire-code are enforced, a protective membrane must be installed on the underside of plated truss floor framing.

Fire code compliance is easy and inexpensive

By only covering the trimmable end of the TRIFORCE® joist, your floor system will be fire compliant as per Exception 4 to Section R302.13 of the 2015/2018 IRC.

Repairs are costly and time consuming.

If a plated truss is damaged or altered, a custom repair detail must be prepared by an engineer, leading to work delay.

Standard repair details are available.

Because TRIFORCE® is a stock product with years of installation experience, engineered repair details for the most common issues are already in existence and utilize repair materials common on job sites.

Cost effective, light and safe.

Superior “strength-to-cost” ratio thanks to no need for steel connectors, and efficient use of wood fiber with a state-of-the-art robotic manufacturing process. All-wood finger-joined joists are installation-friendly for framers and mechanicals.

Certified through testing.

Unlike plated floor trusses, every TRIFORCE® joist is tested to its capacity before leaving the factory. This testing backs up a unique lifetime product warranty.

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.

Using TRIFORCE® instead of plated trusses helps a contractor save on labor and get ahead of schedule!
