it is stronger and live for a long time
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
No, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the conduit.
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.
Conduit is piping for electrical wiring. Steel conduit is the most common conduit used. It is often left visible in industrial atmospheres and can be seen running to electrical outlets, lighting panels, electrical panels, etc.
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.
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.
There are many types of conduit used for the containment of electrical wires. PVC is a non-metallic option. If you need something that provides mechanical protection, EMT is a steel conduit with a thin wall. Need even more mechanical protection, you can use rigid conduit. It comes in steel or aluminum, and must be threaded together.
A 770 Greenlee hydraulic pipe bender bend is used for rigid steel conduit from 2" to 4".
As steel gets harder, it also gets less flexible.
== == Think about it. The conduit is metal, and can be touched by people. It is carrying live wires and is connected to steel junction boxes. What would happen if a hot wire accidentally touched the steel conduit? The ground wire is there to keep the conduit from going live in a fault condition. You want to ground any metal surface a user can touch in case of faults.
Aluminium is more expensive than steel
