You can feel confident with steel conduit for many reasons. Not only does steel conduit protect conductors against a
wide range of physical risks, but it delivers a variety of business benefits, too.
I. Advantages of using steel conduit
Steel conduit provides the best physical protection you can
get. But this is only one of the many advantages of using steel
conduit. Additional benefits include:
âą Protection against impact at all temperatures
âą Deflects hand-driven nails and screws and doesnât
stretch or tear
âą Highest yield and tensile strengths
âą Doesnât burn, contribute to smoke volume, emit
potentially escape-inhibiting fire gases, or add to fuel
load or flame spread
âą Noncombustible and can be fire-stopped with common
building materials
âą Provides an excellent electrical path to ground,
eliminating the need for supplementary equipment grounding
âą Reduces EMF by up to 95% at power frequencies
âą Compatible coefficient of expansion with most construction materials
âą Adaptable and can easily accommodate wiring changes
âą Fully recyclable
The Cost Advantage of Steel Conduit:
Theabilitytofutureprooftheelectricalsystembyusingsteelconduitlowersthetotalcostofthesystemduringitslife
span. Today, the need to replace or upgrade power, data and communications circuits can happen overnight. Requirements
for more sophisticated electronic equipment, increased power requirements or new applications can cause owners and
tenants to demand changes in the wiring of their plants, retail complexes or buildings. Steel conduit is adaptable and can
accommodate these changes, making it easier to pull out old wiring and install new systems. Steel conduit also provides the
quickest and most efficient changeover or upgrading of electrical conductors. It all adds up to make steel conduit the most
cost-effective wiring method over time â and this is only one of the many benefits steel conduit provides.
II. Steel Conduitâs Fire Resistance
WhensteelRMC,IMCorEMTracewaysareusedtopenetrateafire-resistance-ratedassembly
of concrete or masonry, the International Building Code (IBC) allows the annular space to be
filled (sealed) with cement, mortar, or grout instead of having to use a listed firestop system. This
is an inexpensive and readily-available alternative that assures the fire-resistive-rating of the
penetrated assembly is not degraded.
In summary, because steel raceways withstand fire, it is the ideal choice for applications
in places of assembly:
âą Galvanized steel RMC, IMC and EMT are considered noncombustible by the
building codes.
âą Steel raceways were still intact after a UL four hour ASTM E119 test at near 10930
C.
âą Does not add to fuel load or flame spread.

III. Durability of Steel Conduit
Todayâs buildings are designed for life spans of 50 to 80 years - and steel conduit lasts at least
that long, making it the essential component of modern electrical systems. Steel conduit resists all
common forms of wear, ensuring long-lasting performance.
âą Strength to Withstand Mechanical Injury
Steel provides superior protection from physical damage by forklifts or other plant equipment.
âą Superior Corrosion Protection
Unlike other types of metal conduit, galvanized steel conduit can be used in concrete, direct
burial and areas with severe corrosive influences.
âą Lifelong EMI Shielding
Because physical impact and corrosive elements donât compromise its integrity, steel conduit
retains its ability to protect against electromagnetic interference (EMI) over time. Thatâs why you
can rely on steel conduit for applications with highly sensitive computers and data - from banks
and casinos to housing complexes. In todayâs culture, where people often work remotely and pay
bills on their mobile devices, virtually every application benefits from steel conduitâs EMI-shielding
capabilities.
IV. Steel Conduit and Sustainability
Steel conduit supports green building practices by helping reduce
environmental impact throughout a buildingâs life cycle, and contributes to
sustainability through waste reduction, resource conservation and reusability.
Steel Conduit: Recycled and Recyclable
Steel is the worldâs most recycled material, according to the Steel Recycling
Institute (SRI). For this reason, nearly all steel conduit contains recycled steel.
In fact, SRI reports that total recycled content of steel ranges from 32.7%
to 93.3%.According to SRI, steel conduit also has a high reclamation rate because
of its:
âą Long service life - some steel rigid conduit has been in use for
more than 60 years
âą Ability to accommodate new conductors and additional circuits
over time
âą Total recyclability
