Electrical Conduit
An electrical conduit is a tube in which electrical wires are housed for a variety of building or structural applications. Conduit protects wires as well as any individuals who may come into close proximity to the wires.
Rigid Metal Conduit
Rigid metal conduit (RMC) has a thick wall and is constructed of either aluminum or galvanized steel. This variety is one of the most heavy-duty types of conduit used in many industrial applications. Rigid metal is one of the more costly options but offers additional strength.
Galvanized Rigid Conduit
Galvanized rigid conduit (GRC) has the thickest walls of all electrical conduit and is the heaviest. GRC is regarded by electricians for its superior corrosion resistance, and it protects wiring from electromagnetic interference (EMI). GRC can be used in outdoor or indoor applications and can be exposed, concealed and buried.
Intermediate Metal Conduit
Intermediate metal conduit (IMC) is a type of a rigid conduit rated for outdoor exposure and is intended for protecting insulated electrical cables and conductors. It offers much of the same protection of rigid metal conduit but is a more economical option for projects where cost is an issue.
PVC Conduit
Polyvinyl chloride (PVC) conduit is the most popular type of non-metallic conduit and has several advantages:
Liquid-Tight Non-Metallic Conduit
Liquid-tight non-metallic conduit is designed for use in environments where moisture could become an issue. This type of conduit must be used in conjunction with liquid-tight fittings.
Electrical Metallic Tubing
Electrical metallic tubing (EMT) is made from coated steel or aluminum and is a more economical and thinner-walled option than other conduit. This conduit type doesn’t offer the same protection as rigid metal conduit but is lighter and can be paired with conduit fittings, eliminating the need for threading.

The Other Alternative to PVC – PEX
There is one other alternative to PVC and metal pipe for home and commercial plumbing. Cross-linked polyethylene, or PEX, is rapidly becoming a choice for plumbing water systems in homes and commercial occupancies. However, like all other alternatives, PEX has a list of advantages and disadvantages that must be considered for any project.
Rising Prices – The New Normal
The rise in the price of PVC pipe is not an aberration. Almost all building materials have seen major price jumps in the last year. A combination of demand, raw material supply, and logistics challenges have contributed to these price increases. Unfortunately, industry experts expect this trend to continue through the new year.
