Galvanized Rigid Conduit (GRC) is a type of conduit used for electrical wiring protection, similar to Electrical Metallic Tubing (EMT). However, GRC is typically made of galvanized steel and is heavier and more rigid compared to EMT.

GRC is designed to provide robust protection for electrical wires against physical damage, moisture, and other environmental factors. It is commonly used in commercial and industrial applications where additional durability and protection are required.

GRC is known for its high resistance to corrosion due to its galvanized coating, which helps to prolong its lifespan, especially in outdoor or corrosive environments. Like EMT, GRC is available in various sizes and can be bent and shaped to fit specific installation requirements. It is installed using fittings and connectors to create a secure pathway for electrical wires while ensuring compliance with electrical safety standards.
