The reason I asked is there replacing the piping in my plant from 10” to 14” and hanging it from the roof of a “Butler Building”. The question was raised by the fitters if the roof can support this additional weight.
I'm coming up with around 121, don't forget to add the weight of the insulation and hangers! I would defiantly get it checked out by a structural engineer. Don't want that roof collapse on your shoulders.
