Multi-ply Trusses

Multi-ply Truss are fabricated using multiple layers of thinner timbers (normally 2”, 3” or 4” thick) bolted together in some combination of overlapping members. Most of the time the top and bottom chords are comprised of two members “sandwiched” around a single king post and webs. Gusset plates are normally not used, with a series of bolts, nuts and washers holding all layers together. This configuration results in a unique appearance and is sometimes more economical because thinner material is used and no shaped plates are required.

As a general rule of thumb, these trusses are designed with the thickness of the combined layers in the top and bottom chords being equal to the thickness of an equivalent single-layer, solid timber truss. Most Multi-ply Trusses have three sandwiched layers, but SWC has fabricated trusses with thinner components and spacers having up to five layers for a unique appearance.
