What is Rigid Metal Conduit？

   Rigid Metal Conduit is manufactured from high-strength steel coil and produced according to the standard of ANSI C80.1(UL6). The interior surface of our conduit is free from a defect with a smooth welded seam. It is hot-dipped galvanized inside and outside so that metal-to-metal contact and galvanic protection against corrosion are provided, and the surface of the conduit is coated with a clear lacquer coating to inhibit white rust and increase corrosion resistance. And the conduit is threaded on both ends, with a coupling applied to one end and a by size color-coded thread protector to the other as per table. The interior surface provides a smooth continuous raceway for easy wire pulling.  Our conduits ductility characteristics provide for easy bending, cutting, and threading in the field.
