EMT & IMC Pipe

Electrical Metallic Tubing(EMT) refers to the steel-based durable enclosures that route individual electrical wiring conductors in a building or structure and protect the wires from impact, moisture, and chemical vapors.
Intermediate metal conduit, or IMC, is a rigid steel electrical conduit designed for outdoor exposure and strong connections. It was designed specifically to protect insulated electrical conductors and cables. By utilizing IMC in any areas allowed, you can all but eliminate the need for a heavier-walled conduit.
