#18 Rebar

Reinforcing bar or “rebar” is available in a complete range of standard sizes, and #18 rebar is one of the largest and strongest. Rebar works to provide additional stability to concrete structures by reducing the weight load the concrete must bear and enhancing its inherent tensile strength. # 18 reinforcing bar is available in both black and epoxy-coated finishes, and black rebar is the least expensive option and best suited to conditions where it will not be exposed to moisture. For bridges and construction projects in marine environments, epoxy-coated rebar is recommended, as its special finish resists the corrosion caused by water and humidity.

Number 18 rebar is well-suited for large-scale applications including:

  • Parking structures
  • Marine facilities
  • Large buildings
  • Industrial facilities
  • Bridges
