hanging duct from steel corrugated roof deck
hanging duct from steel corrugated roof deck
(OP)
I commonly see the upper attachment for duct hangers to be screwed to the underside of the steel roof deck w/o a concrete overlay I do not see this detail in SMACNA. Is it permitted to hang ductwork from a steel corrugated roof deck or should the duct be supported from the open web steel joist(owsj)? Is there a detail in SMACNA or code for screwing the upper attachment to the deck if permitted?

They will give you restrictions on spacing, loading as well as connection detail. They normally want the connections in the 'valley' between the ridges
