Glued finger joint splices make our wood nailer joists stronger, stiffer, more efficient
WN-Series Steel Joists revolutionize the wood nailer joist market prevalent in the Western states of California, Idaho, Nevada, Oregon and Washington. Unique in their design, our WN-Series Joists are open web steel joists with continuous 2½ (or 2)-inch-thick wood nailers using glued finger joint splices to maintain structural continuity the full length of the joist. This innovative design produces a stronger, more-efficient, better-performing joist.
A steel and wood hybrid product, WN-Series Joists facilitate installation of wood decking over steel joists in the field. They are available in two profiles: parallel chord and single-pitched top chord. Both profiles are available with underslung or square ends with pitches up to 2 inches per foot. Overall depths from 26.5 inches to 50.5 inches and spans from 24 feet to 70 feet.
