SST
Truss is a structural open web plate connected engineered wood component used
as a joist in floor and roof construction. Its
long span high load carrying capacity is achieved by the engineered combination
of face bonding (gluing) and machine stress rated (MSR) lumber which is finger
jointed and tension tested as a continuous member. The
webs are manufactured from visually graded or MSR lumber. All multiple web members
are face bonded (glued). The webs and chords
are assembled and connected with ICBO-ES approved connector plates that are embedded
in the wood components by a series of precision presses. Performance
Features - Longer span capacity yields greater
design flexibility
- Wider bay designs resulting
in fewer columns
- Camber as required by design
- Conventional framing width of 3 1/2"
reduces the span of the sheathing allows for more nailing or gluing area
- Parallel
chord, single or double taper designs available
- Continuous,
tension tested chords, laminated when multiple plies are utilized
- Light
weight and dimensionally stable
- Open web
allows easy installation of mechanical, electrical and other trades
- Split
resistance (R chord) allowing for tight diaphragm nailing is available.
- Allows
for direct connection for lateral design load transfer
- Moisture
content of all chords and webs is limited to 15% for maximum product stability
