It’s important to choose the right wiring method for your project. Aluminum electrical metallic tubing (EMT) from American Conduit provides excellent mechanical protection for conductors and cables, can replace steel EMT in virtually all locations, and will save you thousands of dollars on every job.
American Conduit is a product brand of Hydro, a fully integrated aluminum company that serves about 30,000 customers globally. We have more than 35 years of experience in the production of aluminum electrical metallic tubing and rigid aluminum conduit. Our nationwide distribution network ensures convenient access for customers from coast to coast.
What is EMT?
EMT is an unthreaded, thin-walled tubing typically made of galvanized steel or aluminum. Often called “thin-wall conduit,” it is technically considered tubing. It is used to protect electrical wiring from moisture, chemicals, and even from pests that can chew through wiring and cause a short.
EMT is connected using clamp-type fittings that slide onto the tubing and are secured with a set-screw. It is popular in commercial and industrial applications because it is lighter and thinner than rigid metal conduit and is relatively easy to bend and cut.
It provides both physical protection and corrosion resistance, and can be used in exposed, concealed or wet locations. EMT can also be used as an equipment grounding conductor, eliminating the need for a separate grounding conductor, and simplifies future wiring changes.
Consider the Benefits of Aluminum EMT
Aluminum EMT is an excellent substitute for steel EMT. It is UL listed and meets the same code requirements as steel. It is one-third lighter than steel, easier to maneuver, and provides cost savings in terms of installation and maintenance.
Aluminum EMT is generally used in applications that require higher corrosion resistance, such as in food processing plants, where large amounts of water and chemicals make galvanized steel unsuitable.
Aluminum EMT helps block the electromagnetic radiation emitted by electrical circuits that causes unwanted interference and noise. And, when installed with proper fittings, it provides greater protection from fire and explosions by preventing the flow of flammable gases and fumes from volatile substances.
Aluminum EMT conduit can be easily cut and bent in the field and does not require many manufactured fittings. Although it cannot be threaded, threaded fittings can be clamped to it. This is a major advantage, particularly when following irregular or curved building profiles.
Other important advantages of aluminum EMT include:
- Lower cost than steel EMT
- Inherent EMI shielding
- Better thermal and electrical conductivity
- Natural oxide film provides exceptional corrosion resistance
- Non-magnetic; non-sparking; non-combustible
- Non-toxic even at high temperatures
- No rust, streaking or discoloration
- Virtually maintenance free
- UL Listed
- Adheres to ANSI C80.3
- National Electric Code® (NEC) compliant
- Readily available and in stock
