PWI42S Series I-Joist 3-1/2" x 18"

PWT I-joists are more versatile than open web floor trusses, and more uniform and dimensionally stable than lumber. They can be trimmed on-site, and long lengths allow ceilings and floors to be designed with fewer pieces, saving installation time. Build sturdy, stable floors with wider flanges.

These I-Joists combine finger-jointed sawn wood flanges with a web of oriented strand board (OSB) to produce an I-shaped structural member. Both materials work together to resist deflection, bending stresses and shear.

The 3-1/2" solid sawn flanges are individually tension proof loaded after finger jointing.
