CFS Strut

Simpson Strong-Tie introduces the HYS hybrid strut, the first cold-formed steel strut to be assembly tested for both slide- and rigid-clip applications. Commonly used at the bottom of steel beams to accommodate standoff conditions, the HYS can be attached with screws, power-actuated fasteners or welds, allowing erectors flexibility for improved jobsite efficiency and productivity.


Input from CFS erectors in the field was central to the development of the HYS, which also included comprehensive component-to-steel-fixture, assembly and anchor testing. Real-world assembly testing further allowed Simpson Strong-Tie to tabulate accurate loads based on both strength and deflection to assist in mitigating design risk.


For installation as a slide connection, the HYS easily attaches with shouldered screws driven through the slotted holes. The clip comes with shouldered screws specially designed and precision-manufactured to prevent over-driving and to ensure that the connection functions properly in slide applications. For installation as a rigid connection to support gravity and lateral loading, the clip can be attached with No. 10 screws through the small predrilled holes. Additional features of the HYS include a Simpson Strong-Tie® No-Equal® stamp marking the center of the HYS slots to help ensure correct placement of shouldered screws. The HYS slots are positioned to minimize eccentric loads and maximize capacities.


Another feature is up to 1” of vertical moment in each direction when shouldered screws are centered in the vertical slot for slide applications.


The struts are available in standard lengths of 12", 15", 24" and 30".
