RMC (Rigid Metal Conduit) is a heavy-walled, threaded raceway manufactured from electric resistance welded (ERW) steel. Designed for extreme-duty applications, it provides superior mechanical impact resistance and serves as an effective grounding path.
The conduit features a hot-dip galvanized coating that complies with ASTM A153, providing exceptional corrosion resistance for use in direct burial, chemical immersion, and marine environments.
