Electrical metallic tubing is a lightweight conduit that is used to encase electrical wires within a structure. Although there are several other piping materials available, this type is one of the more common choices by contractors because it is more cost-effective than comparable materials. Steel are the two main choices used to make the tubing, and in many cases, it is also galvanized with zinc coating so that is will remain resistant Unlike many of the other options within electrical tubing, EMT does not thread together; instead, the ends are fitted to clamps.
