These details show channel strut and tube strut attachments connected to a twenty-gauge minimum metal deck with insulation above or directly to a steel beam with fireproofing. Option 1 for the channel strut uses a twelve-gauge clip angle measuring one-and-one-half inches by one-and-one-half inches secured with two number twelve sheet metal screws into the metal deck, and two number ten sheet metal screws connecting the strut. Option 2 utilizes a twelve-gauge clip measuring two inches by two inches by zero feet eight inches minimum attached with two number twelve sheet metal screws and two number ten sheet metal screws. Tube strut options feature either a flattened end or a slotted end connected via ten-gauge or twelve-gauge clip angles placed tight to the clip or structure. Steel beam attachments involve cutting and bending flanges or using clip angles fastened with number ten sheet metal screws, with structural steel members required to be no less than three-sixteenths of an inch thick.
