What Material is Electrical Conduit Pipe?

Electrical conduit pipes are an essential component in electrical installations. They protect wires and cables from damage, prevent electrocution, and provide a safe pathway for electricity to flow. However, not all electrical conduit pipes are created equal. The type of material used in their construction can greatly impact their strength, durability, and performance. In this article, we will explore the different materials used in electrical conduit pipes and help you choose the right one for your electrical installation project.

Types of Electrical Conduit Pipes

There are two main types of electrical conduit pipes: metallic and non-metallic. Metallic conduit pipes are typically made of steel, aluminum, or copper, while non-metallic conduit pipes are made of materials like PVC, HDPE, and fiberglass.

Metallic Electrical Conduit Pipes

Steel is the most common metallic material used in electrical conduit pipes. It is strong, durable, and resistant to corrosion, making it an excellent choice for outdoor and industrial installations. However, steel conduit pipes are heavy and difficult to install in tight spaces.

Aluminum conduit pipes are a lightweight alternative to steel conduit pipes. They are easy to install and have good electrical conductivity. However, they are not as strong as steel and may be prone to bending and denting.

Copper conduit pipes are the most expensive metallic conduit pipes but offer superior electrical conductivity and durability. They are often used in high-end residential and commercial installations.

Non-Metallic Electrical Conduit Pipes

PVC is the most common non-metallic material used in electrical conduit pipes. It is lightweight, easy to install, and affordable. PVC conduit pipes are also resistant to corrosion, making them suitable for outdoor installations. However, they may become brittle over time and may not be suitable for high-temperature environments.

HDPE (high-density polyethylene) conduit pipes are lightweight, flexible, and resistant to impact and corrosion. They are suitable for underground installations and can withstand extreme temperatures. However, they are more expensive than PVC conduit pipes.

Fiberglass conduit pipes are lightweight, strong, and resistant to corrosion and chemicals. They are suitable for harsh environments and hazardous locations. However, they are more expensive than other non-metallic conduit pipes.

Choosing the Right Material for Electrical Conduit Pipes

When selecting the material for electrical conduit pipes, there are several factors to consider. Cost, durability, and corrosive environments are important factors to consider when selecting the material.

For outdoor installations or in corrosive environments, metallic conduit pipes are a better choice. Steel conduit pipes are the most durable and resistant to corrosion, but aluminum and copper conduit pipes may also be suitable depending on the specific requirements of the project.

For indoor installations or in areas where weight is a concern, non-metallic conduit pipes are a better choice. PVC conduit pipes are the most affordable and lightweight, but HDPE and fiberglass conduit pipes may be more suitable for harsh environments and hazardous locations.

It is also important to comply with electrical codes and regulations when selecting and installing electrical conduit pipes. Electrical codes and regulations vary by location, so it is important to consult with electrical professionals to ensure compliance.


In summary, selecting the right material for electrical conduit pipes is essential for a safe and reliable electrical installation. Metallic and non-metallic materials each have their own advantages and disadvantages, and the choice depends on several factors such as cost, durability, and corrosive environments. By following electrical codes and regulations and consulting with electrical professionals, you can ensure that your electrical installation project is safe and reliable.
