Electrical Metal Tubing (EMT) is an unearthed Hot Dipped Galvanized steel raceway of circular tube.The interior of the conduit is a smooth continuous raceway and is coated with zinc organic lubricants.
IMC Conduits are produced as a cross between EMT and RMC Conduits. Weighs 1/3” less than a typical RMC Conduit but has a larger inside diameter allowing for easier wire pulling.
