Galvanized Rigid Channels

Galvanized Rigid Conduit (GRC or RMC) is a heavy-wall, threaded, hot-dip galvanized steel tubing designed for superior mechanical protection, corrosion resistance, and grounding capabilities, making it the standard for high-duty utility and industrial applications. It is suitable for both exposed and direct burial installations, offering protection against damage from rodents, vehicles, and harsh environmental conditions.

Common Galvanized Rigid Conduit (GRC) and Fittings for Utilities:

Conduit Sizes: Available in trade sizes ranging from 1/2 inch to 6 inches, with 2-inch commonly used for service entrances.
Fittings & Accessories:
- Couplings & Nipples: Threaded fittings to securely join conduit sections.
- Elbows: Large radius 45° and 90° elbows for smooth wire pulling.
- Hubs & Connectors: Watertight hubs (bullet hubs) and compression connectors to attach conduit to boxes or enclosures.
- Straps & Clamps: One-hole or two-hole straps to secure conduit.
- Bushings: Plastic-insulated bushings to protect wires.
- Service Entrance Caps: Used to terminate conduit

Key Features & Applications:

Corrosion Resistance: Hot-dip galvanized inside and out.
Compliance: Meets ANSI C80.1, UL 6, and NEC standards.
Durability: Non-combustible, provides superior protection against arc flash and physical impact.
Industry Standards: Often preferred for utility-grade, long-lasting, and heavy-duty infrastructure projects.
