What Is Electrical Metallic Tubing?

Electrical Metallic Tubing (EMT) is a lightweight, used to enclose wire conduits in structures. Although there are other pipeline materials, this type is one of the more common choices made by contractors because it is more cost-effective than similar materials. Steel and aluminum are the two main choices used to make the pipe, and in many cases it is also galvanized with a zinc coating so that it will remain corrosion-resistant. The EMT is not connected in series with many other options within the tube, but instead is mounted to the fixture at both ends.

This tube is the most popular choice for indoor and outdoor use because it is the lightest steel packing on the market. Because it is constructed of a premium metal, it controls the entire route created, and in fact many areas specify that EMT must use electricity flow that meets building standards. Non-metallic pipes are also more susceptible to moisture, which is dangerous for free flowing electricity around. The effect of exposure to chemical vapors or the protection of accidental blunt forces also uses this type of pipe, and even light metal plating is superior to none at all.
