General Characteristics
The P3 Joist™ is an “I”-shaped engineered wood structural product designed for use in residential and commercial floor and roof construction.
P3 Joist™ products are prefabricated using SPF MSR lumber flanges and OSB web, which are bonded together with exterior-type adhesives. These products are identified by their depth, followed by their series name PJI, and by a designation – such as 40 – which relates to the joist’s strength and stiffness. These products are manufactured to strict tolerances.
- All P3 Joist™ products are manufactured in conformance with ASTM D5055.
- Webs are OSB, classified as Exposure 1 or Exterior, and 3/8” in thickness or greater.
- All P3 Joist are assembled using exterior-type adhesives that meet ASTM D 2559 and ASTM D 7247.
- P3 Joist are available in seven depths: 9-1/2”, 11-7/8”, 14”, 16”, 18”, 20” and 24”.
- P3 Joist of the same depth are manufactured with various flange widths; flange width is an important design consideration when specifying hangers.
- P3 Joist are manufactured up to 64’ in length. These lengths are cut to commonly used lengths such as 16’ to 36’ in 2’ increments for jobsite delivery.
