6 Types of Electrical Conduits

Electrical conduits are used when installing new electrical wiring to help provide the route and give a high level of protection. It is made in many different materials, including fiber, plastic or mental and can be flexible or stiff. Here are a few of the most popular types of electrical conduits:

Galvanized steel

The galvanized steel conduit is thoroughly stiff to provide useful protection for the electrical wiring. This method is most shared in industrial or commercial electrical installation. The typical length of the conduit is in the vicinity of 10 to 20 feet, and multiple pieces are easily threaded together. Plus, it is easy to protect against corrosion by applying the right protecting paint. It is one of the thickest and heaviest in weight to make it a functional choice for the most difficult environments.


Metallic tubing (also referred to as EMT) is mostly made of aluminum or steel. It is more cost-effective and lighter than the alternatives in galvanized steel. This conduit is flexible to give more freedom in installation and a popular choice with industrial and commercial buildings. Also, the outer surface is naturally corrosion resistance, so there isn’t any need to provide a special coating.

Electrical non-metallic

The electrical non-metallic tubing is made of a thin, corrugated kind material that is flame retardant and moisture-resistant. It has high flexible similarities and is easily shaped by hand to fit the tight or awkward spaces. This is a perfect kind of conduit for those in search of low labor costs and fast installation.

Flexible Metallic

The standard flexible metallic conduit is a functional choice for the dry environments and is simply a hollow tube with space for the electrical wires to pass by. There is also a liquid-tight flexible conduit in metal that has a waterproof coating. This is more functional for the damp locations and can be encased in concrete or buried in other areas.


PVC is the most shared kind of conduit used for residential and commercial installations. It is a very affordable option and the PVC pipes are thick to give a useful amount of protection. PVC is naturally able to avoid issues with corrosion and resists moisture.

Aluminum Electrical

The aluminum conduit is a stiff option for the commercial applications and a functional option for areas that are inclined to high moisture content. It is a useful choice to use in concrete slabs or walls, but cannot be buried in concrete because the alkali content in the cement can cause a negative reaction.
