Fiberglass rebar, also known as FRP, GFRP or composite rebar, is a type of concrete reinforcement material that is made from fiberglass roving and resin. It is a more durable, proven and successful alternative to steel rebar in many applications.

Advantages of Fiberglass Rebar

Fiberglass rebar has several advantages over steel rebar, such as:

Stronger: Fiberglass rebar has 2x the tensile strength compared to steel¹².

Lighter: Fiberglass rebar is up to 7x lighter in concrete flatwork applications and 4x lighter compared to the same size diameter¹². This reduces the transportation and labor costs and improves the productivity and safety of the construction site.

Rustproof: Fiberglass rebar will never rust, corrode or deteriorate, enabling more durable and longer-lasting structures. This also reduces the maintenance and repair costs and extends the service life of the concrete structures.

Non-conductive: Fiberglass rebar is electrically and thermally non-conductive, which makes it suitable for applications where electromagnetic interference or thermal expansion are a concern, such as near power lines, MRI machines, airports or bridges.

Applications of Fiberglass Rebar

Fiberglass rebar can be used for various residential, commercial and structural applications that require concrete reinforcement, such as:

Parking lots

Sidewalks

Patios

Pool decks

Driveways

Bridge decks

Barriers

Seawalls

Balconies

And more

Code Approval and Standards of Fiberglass Rebar

Fiberglass rebar meets the physical and mechanical requirements of ASTM D7957 material standards¹². It is also code-approved for residential building code¹. Fiberglass rebar can be designed and installed according to ACI 440.1R guidelines³.

Conclusion

Fiberglass rebar is a new standard in concrete reinforcement that offers superior performance, durability and cost-effectiveness compared to steel rebar. It is a versatile and innovative material that can be used for various applications that require stronger, lighter and more durable concrete structures.
