IMC Conduit

IMC Conduit

Intermediate Metal Conduit Electrical Pipe with Couplings

Intermediate Metal Conduit (IMC) are metal pipes manufactured for the Electric Cable Wire Protection. There are 3 types of Electrical Conduits which includes EMT (Electrical Metallic Tubing), IMC (Intermediate Metal Conduit) and RMC (Rigid Metal Conduit). IMC Conduit manufacturers in India supply these Conduit as per BS4568, UL-1242 and ANSI C80.6 standard.

What is IMC Conduit?

IMC Conduit means Intermediate Metal Conduit Pipe and Tubes. These IMC Pipe are produced in various alloys such as Mild Steel, Carbon Steel, Stainless Steel and Aluminium. IMC Electrical Conduit give protection to electric wire cables in Indusrial and commercial sector.

IMC Conduit complies with UL-1242 and ANSI C80.6
