The TrimJoist system's open web design allows subcontractors to easily, practically and quickly run electrical work, duct work and plumbing throughout the flooring system of any building. Running mechanical systems through the trusses instead of below them gives architects more design flexibility.

Because each TrimJoist is trimmable on-site, contractors can always achieve a custom fit without the risk and lead time from standard custom floor trusses.

Each joist has a 3.5-inch-wide nailing flange on the top and bottom, virtually ensuring a non-squeak floor when properly installed. The extra-wide nailing surface provided by the TrimJoist makes for a superior installation and more satisfied owners.

The TrimJoist floor system is manufactured entirely in the United States. This allows for us to employ those in our local community, achieve a higher standard of quality control and guarantee timely delivery.

Trimjoist introduced the first trimmable floor joist system to the building industry and is the only corporation with a patent on a trimmable floor joist.

Since the TrimJoist is available from stock at any authorized dealer, there are no lead times. Any overage or underage can be handled by your building supplier — not a factory, which may impose a surcharge for an “extra” joist.

Trimjoist’s in-house engineering staff is always on hand to assist contractors, architects and building designers in plan conversion and design layout. They provide detailed floor-framing plans and precise material lists for each project, which ensures the joists are shipped and installed right the first time.

Trimjoist’s full-time technical support team is always available for support during installation of Trimjoist products.
