About GFRP

Fiberglass rebar marketed for use in Canada or the U.S.A. must have third party test results. The results are used to give each bar a designation in accordance with ISIS, CSA and ACI standards. The Specifications Chart section in this website illustrates third party test results for TUF-BAR™.

Fiberglass rebar is made of high strength fibers in a polymer resin matrix. Similar resins are used to make containment vessels for highly concentrated acids, chlorine, alkali’s and other chemicals. The fibers in a GFRP composite are the main load-carrying element and exhibit very high strength and stiffness when pulled in tension. A GFRP rebar will typically consist of millions of these thin, thread-like fibers. Damage to the exterior of the rebar does not degrade the rebar’s resistance to corrosion.

Fiberglass rebar comes in many types some of which are listed below:

Sand-coated on a smooth bar

  • The sand coating is primarily responsible for bonding with concrete. Sand coating also reduces crack width in applications where concrete is exposed to heavy fatigue loading applications. This type of application is found in bridge deck, loading dock, and driveway construction.

Sand-coated on a deformed bar

  • This type of fiberglass rebar has a sand coating on an underlying deformed surface essentially giving two layers of bond. It is more resilient to a drop in bond strength if some sand coating is lost during shipping or handling. It is ideal for heavy fatigue loading applications found in bridge decks, loading docks, driveway, power pole, or truck scale applications.

Un-sand coated Smooth Bar

  • Usually used in dowelling applications, it is not recommended for beam applications.

Threaded GFRP

  • Ideal for form ties, barrier anchors, sea wall tiebacks, floating docks, soil nail or rock bolt applications. In many applications GFRP’s are a good alternative to stainless steel fasteners since they exhibit superior corrosion resistance in acidic and in salt-water environments.

Bent Bar

  • The manufacturer  of GFRP rebar prefabricates bends.  FRP Distributors generally keeps a family of prefabricated bends in inventory to meet customer’s immediate requirements.
