Why steel’s a better deal! You only get what you pay for. So, before you choose your wiring system, compare all the costs and benefits.

For instances:
Steel conduit does not burn, contribute to smoke volume, emit potentially escape-inhibiting fire gases, or add to fuel load or flame spread. Since its noncombustible, it can be fire-stopped with common building materials. That means added safety and lower life-cycle costs.
Steel conduits are tough. It protects against impact at all temperatures: deflects hand-driven nails and screws: does not stretch or tear and has the highest yield and tensile strengths, less installation damage and reduced potential for future problems.

Steel conduit provides an excellent electrical path to ground, so supplementary equipment grounding is not required. Another cost saving.
Steel conduits reduce EMF by up to 95% at power frequencies and easier to avoid EMI issues. Steel conduit has a compatible coefficient of expansion with most construction materials. Fewer, if any expansion joints are required. Saves time and materials. Steel conduit is adaptable to changing needs. Ever consider the cost of changing circuits that aren’t installed in conduit? Now. That’s expensive.

Steel conduit. Cost savings in both the short and long-run. That is why steel’s a better deal.
