About this detail

Options for hanging electrical metallic tubing and channel struts from a fireproofed structural steel beam. Option 1 utilizes a ten-gauge angle clip secured to the underside of the beam flange with two minimum zero point one four five inch diameter power-actuated fasteners, connecting to a flattened tube end with two number ten sheet metal screws placed tight to the clip or structure. Option 2 features a similar angle clip connected with two number ten by two-inch sheet metal screws through a slotted tube end. The channel strut option involves cutting and bending the flanges and securing with two power-actuated fasteners directly into the beam flange. Structural steel members must not be less than three-sixteenths of an inch thick. Contractors must verify that no power-actuated fasteners are installed within the protected zone of any steel member per AISC 341.
