The prices of PVC conduit seem to be a bit cheaper than steel conduit. PVC is light and lower in cost to produce and manufacture. Depending on the place that the conduit is needed, can determine the type of conduit you need.
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.
One can buy a steel conduit online at various websites. One can purchase a steel conduit online at websites such as the Home Depot and Lowe's official websites.
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.
Heavy wall threaded conduit comes in steel or aluminium. The aluminium conduit is NOT galvanized because you can not galvanize aluminium. Steel conduit used to come in two types: ENAMEL and GALVANIZED. The ENAMEL was not approved for outdoor or wet locations and is not currently generally commercially available but is still found in many existing buildings. It is NOT galvanized. The GALVANIZED type is approved for all locations.

One can find information about conduit fittings from various sources. Some of those sources are Grainger, Home Depot, Prime Conduit, Steel Conduit and Lowes.
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.
There are no advantages or disadvantages over which type of junction box to be used on electrical wiring. As long as the junction box is of an approved type (CSA or UL approved). It is cost or location which dictates which boxes will be used. PVC boxes for home wiring are the cheapest. Aluminium or steel are usually used in rigid or EMT conduit systems. PVC again when the conduit system involves underground wiring. In large electrical installations it is the electrical engineer that states what the conduit system type is and what type of electrical junction boxes that must be used.
It depends on the size of the service to be installed. For a 200 amps service, a free standing mast is 2 inch rigid steel galvanized pipe and schedule 40 in strength.
