steel and plastic conduits
it is stronger and live for a long time
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
Yes, any flexible conduit that has live wires drawn into it must have a ground wire also installed with the "hot" conductors. The reasoning behind this rule is that the flex in the conduit is coiled and has a long length to it. The continuation of the grounding medium through the tightness of the conduit connectors to the flex was not considered a properly secured grounding system so to overcome this weakness in the grounding system, a ground wire now has to be installed.
steel and plastic conduits
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.

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.
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.
No, steel is a metal.

Steel is strong and durable. Steel is also easy to mold into different shapes. Cars are also being made out of aluminum, plastic, and carbon fiber.
Using plastic over steel wings on a windmill is a good idea because the steel will eventually rust. The steel is heavier and the motor on the windmill will have to work harder to turn steel, than plastic. The cost of the plastic is actually a little more than steel, though.
Sprockets can be made from a number of different materials. The most popular materials for sprockets are: cast iron, plastic, steel, and stainless steel.
