K-Series Bar Joists
K Series bar joists are designed for use typically with lighter loads and are most common in roof design. K Joists are used typically where shorter span conditions are required.
Disclaimer: Bar joists are an engineered product and can only support their required design load if the “system” is designed and installed properly. The Engineer-of-Record (EOR) is responsible of designing this system that includes but not limited to bridging, supports, connections, anchors and specific design loads. It is the purchasers responsibility to ensure that joists and bridging purchased will be selected, erected and installed properly.
Description
The use of K Series joists in the framing of floors and roofs offers huge advantages when compared to wood truss and steel beam systems. These joists easily handle spans that wood systems cannot handle while their lightweight construction makes them much less costly than steel beams. K Series joists range in depth from 10” to 30” and can span up to 60’.
