    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 LH Series joists are used for longer span conditions where heavier loads are required. These joists easily handle spans that other systems cannot handle while their lightweight construction makes them less costly than crustal steel beams. LH Series joists range in depth from 18” to 48” and can span up to 96’-0".
