Metallic conduit is very simply conduit made from a metal material. However, there are varying types of metallic conduit that include: rigid metal conduit (RMC), galvanized rigid conduit (GRC), intermediate metal conduit (IMC), and electrical metal tubing (EMT). EMT is sometimes referred to as "thin-walled" conduit as it is a thinner metal than both the RMC, and GRC. Graybar offers a great selection of EMT as well as RMC. Take a look at the steel rigid conduit, steel flexible conduit, aluminum flex conduit and aluminum rigid conduit. Graybar also provides conduit elbows in this category of product and conduit fittings, which are located in the product category of Fittings.
