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.


The use of DLH Series joists are used for shorter span conditions where lighter loads are required while requiring constant shear and moment. These joists easily handle spans that wood systems cannot handle while their lightweight construction makes them much less costly than steel beams. DLH Series joists range in depth from 10” to 30” and can span up to 60’.
