Performance Attributes

More Durable
Cost Competitive
  • Stronger

    2X the tensile strength compared to steel.

  • Lighter

    75% lighter than steel; ease of handling, labor and freight savings.

  • Cost Competitive

    Competitive and consistent pricing.


    Electrical isolator and thermal insulator.

  • Applications

    Corrosion of internal reinforcing steel is one of the chief causes of failure of concrete structures. Inevitable concrete will crack, creating a direct avenue for chlorides to begin oxidizing the steel rebar. Fiberglass Rebar is a proven and successful alternative reinforcement that will give structures a longer service life in many types of applications such as: Bridge Decks I Marine Structures — Sea Walls I Balconies I Tunneling & Mining — Soft Eye I High Voltage & Electromagnetic Fields — Light & Heavy Rail I Civil Roadways I Masonry strengthening & Historic Preservation

In general, field handling and placement is the same as for epoxy or galvanized steel bars. Do NOT shear FRP bars. When field cutting of FRP bars is necessary, use a fine blade saw, grinder, carborundum or diamond blade. Sealing the ends of FRP bars is not necessary. Support chairs are required at two-thirds the spacing of steel rebar. Plastic coated tie wire is the preferred option for most projects. When completely non-ferrous reinforcing, i.e., no steel is required in the concrete, nylon zip ties (available from local building materials centers) or plastic bar clips are recommended. (Don’t forget to use non-metallic form ties in formwork.) It is possible, especially in precast applications, for FRP bars to “float” during vibrating. Care should be exercised to adequately secure FRP in the formwork. <p> <br> <h4>Material Certs, Traceability and Storage</h4> Available for any production lot of AslanTM 100 bar, traceable by bar marks imprinted on the bar in intervals showing the bar diameter, stock order and production date. For storage Fiberglass Rebar should remain covered and protected from UV exposure until ready for use and placement.<p>
