NFPA 13 requires that all hangers be ferrous (contains iron, the primary component of steel), unless specifically approved. I do not know of a non-metallic hanger rod. Stainless would be the best option. You might be able to use regular plated rod if you coated it with spray galvanize in place, but I would have to do more research. BTW, how are the sprinklers? Are they coated?
