Difference between emt and imc conduit

EMT (Electrical Metallic Tubing):

1. Material: EMT conduit is typically made of galvanized steel. It has a thinner wall compared to IMC, which makes it more lightweight and easier to work with.

2. Flexibility: EMT conduit is relatively flexible and can be easily bent and manipulated during installation. This flexibility makes it suitable for applications where the conduit needs to follow curves or bends.

3. Corrosion Resistance: EMT conduits are coated with a layer of zinc for corrosion protection, but they are not as corrosion-resistant as some other types of conduit, like rigid metal conduit (RMC).

4. Use Cases: EMT is commonly used for indoor electrical installations in residential and commercial buildings. It's suitable for runs that are not exposed to harsh physical damage or extreme environmental conditions.

IMC (Intermediate Metal Conduit):

1. Material: IMC conduit is also made of galvanized steel, but it has a thicker wall compared to EMT. This thickness provides greater mechanical protection for wires and cables inside.

2. Rigidity: IMC conduit is more rigid and less flexible than EMT. It is better suited for applications where the conduit needs to resist crushing or impacts.

3. Corrosion Resistance: Due to its thicker wall and galvanized coating, IMC conduit offers better corrosion resistance compared to EMT. It can be used in outdoor and damp environments.

4. Use Cases: IMC is often chosen for industrial applications, outdoor installations, or areas where the conduit may be exposed to physical damage. It's suitable for locations where enhanced protection is required.
