Rmc

Does this come as either RGS or just RMC which would be "not" galvanized?

Here is what the NEC says about RMC. I think RGS is rigid galvinized steel which is what most RMC is made from.

344.2 Definition.
Rigid Metal Conduit (RMC). A threadable raceway of circular cross section designed for the physical protection and routing of conductors and cables and for use as an equipment grounding conductor when installed with its integral or associated coupling and appropriate fittings. RMC is generally made of steel (ferrous) with protective coatings or aluminum (nonferrous). Special use types are red brass and stainless steel.
