SST Purlin is a structural open web plate truss ideal for panelized roof systems.

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) in accordance with ANSI A190.1.

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. Moisture content of all lumber is limited to 15% for maximum product stability.

Performance Features

• Longer span capacity yields greater design flexibility
• Wider bay designs resulting in fewer columns
• Camber as required by designConventional framing width of 3 1/2 reduces the span of the sheathing allows for more nailing
• 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, sprinkler and other trades
• Includes factory installed split resistance top chord (R Chord) allowing for tight diaphragm nailing (see R Chord Specifications)
• Allows for direct connection for lateral design load transfer
