Rigid Steel Conduit (RSC), also known as Rigid Metal Conduit (RMC), is the heaviest-duty protective raceway used in electrical wiring systems. Manufactured from high-strength galvanized steel, RSC provides superior mechanical protection, excellent corrosion resistance, and long-term performance in demanding environments. Its thick wall structure allows it to withstand physical impact, harsh weather, and corrosive conditions, making it the preferred choice for industrial, commercial, and infrastructure projects.
RSC is commonly installed in power plants, manufacturing facilities, transportation systems, outdoor installations, and areas where electrical wiring must be fully shielded from moisture, chemicals, and mechanical stress. It can be threaded, welded, or connected using threaded fittings, ensuring secure and code-compliant installations.
Designed to meet ANSI, and IEC performance standards, Rigid Steel Conduit supports safe grounding, reliable conductor protection, and long-lasting performance in both indoor and outdoor environments. Its unmatched durability makes it one of the most reliable conduit systems for high-risk applications.
