The three types of steel conduit used today—rigid metal conduit (RMC), intermediate metal conduit (IMC), and electrical metallic tubing (EMT)—are, well, made of steel, a noncombustible, crush-resistant material that will last (or outlast) the lifespan of any building.
Steel conduit saves—from the cost of installation throughout the life of a building. When it comes to new construction, steel conduit does not require a ground wire to enhance the safety of the installation, meaning budgeting for additional conductors is unnecessary. Plus, due to steel conduit’s flexibility and reusability, even as a building changes drastically over the years, conduit electrical raceways can be left in place, saving you the recurring expense of replacing cabling as the building evolves.
The recognition of steel conduit’s resiliency is a modern and positive trend. For a century, steel conduit has been an industry go-to, thanks to its superior protection against physical damage. But as we face greater natural and manmade disasters, building a stronger infrastructure is increasingly important—and steel conduit is the perfect electrical raceway because it allows for wiring to be removed, changed, updated, and for the raceway to be reused, something that’s generally not feasible with cabling methods. The conduit raceway can even be flushed out and cleaned, if necessary in cases involved flooding, in preparation for new wiring to be installed.
The longevity and reusability of steel conduit supports sustainable building practices. Steel can be recycled endlessly and used for nearly any purpose. Steel conduit also helps reduce environmental impact with its long service life (some RMC has been in use for more than 60 years) and ability to accommodate new conductors and additional circuits—allowing raceways to be reused over time.
Steel conduit is allowed everywhere. The National Electric Code implements rigorous restrictions on all types of materials, but steel conduit has always been allowed everywhere.
Made of noncombustible material, steel conduit protects against fire and explosions. For any place in a building that fire could reach, steel conduit is easy to install, provides additional protection against fire damage, and will not burn. In locations like gas stations or grain elevators with high explosion risks, RMC and IMC steel conduit protects conductors so they don’t become a source of ignition.
To meet industry standards and NEC requirements, steel conduit has to be provided with corrosion protection. Steel rusts. So steel conduit goes through several preventative processes, such as zinc galvanizing and conversion coatings, to ensure extreme elements won’t cause rapid deterioration.
Because of its steel construction, steel conduit can protect highly sensitive data from electromagnetic interference. Just imagine the banking information whizzing through electrical circuits or the cables powering the monitors or other sensitive equipment in an operating room—all of that information travels through wiring and electrical raceways. Steel conduit’s superior protection against EMI will protect whatever data or equipment that is currently in service in your building now, or that will be at any point in the building’s future.
