Steel conduit weighs more, provides more protection, and costs more than plastic conduit. Plastic conduit weighs less, is easier to work with, and costs less than steel conduit.
steel and plastic conduits
In electrical terms it represents Rigid Steel Conduit. It is also known as Rigid Metal Conduit (RMC).This is not to be confused with Electrical Metallic Tubing (EMT) also known in the trade as thin wall conduit.
PVC is cheaper but is used differently. PVC is usually baried in ground and emt usually runs exposed. You can use PVC exposed if it is schedule 80 gray PVC electrical conduit. Schedule 40 is for under ground
EMT (Electrical Metallic Tubing) conduit is considered nonferrous because it is typically made of galvanized steel or aluminum, which do not contain significant amounts of iron. While galvanized steel does contain iron, the term "nonferrous" generally refers to metals that do not rust or corrode like ferrous metals. Therefore, EMT is primarily categorized as a nonferrous conduit due to its corrosion-resistant properties.
Steel conduit weighs more, provides more protection, and costs more than plastic conduit. Plastic conduit weighs less, is easier to work with, and costs less than steel conduit.
In the true definition of a conduit yes a steel sleeve is in that category.
One can find information about conduit fittings from various sources. Some of those sources are Grainger, Home Depot, Prime Conduit, Steel Conduit and Lowes.

One could purchase aluminum conduit at home improvement retailers such as Home Depot, Lowe's or Rona. One could also order it through a wholesaler such as American Conduit.
Usually in the industry, we call it metal conduits. Metallic conduit is stronger, more durable, and more fire-resistant than non-metallic conduit. It is often used in industrial, commercial, and hazardous environments. Which included, Rigid Metal Conduit(RMC) Electrical Metallic Tubing (EMT) Intermediate Metal Conduit (IMC) Galvanized Rigid Conduit (GRC) Flexible Metal Conduit (FMC) Liquid-tight Flexible Metal Conduit (LFMC) Hope it works.
Another name for thin wall conduit is EMT (Electrical Metallic Tubing). It is a type of conduit made of steel that is commonly used for protecting and routing electrical wiring in commercial and industrial construction.
In electrical terms it represents Rigid Steel Conduit. It is also known as Rigid Metal Conduit (RMC).This is not to be confused with Electrical Metallic Tubing (EMT) also known in the trade as thin wall conduit.
A 770 Greenlee hydraulic pipe bender bend is used for rigid steel conduit from 2" to 4".
Aluminium is more expensive than steel
As steel gets harder, it also gets less flexible.
PVC is cheaper but is used differently. PVC is usually baried in ground and emt usually runs exposed. You can use PVC exposed if it is schedule 80 gray PVC electrical conduit. Schedule 40 is for under ground
