GFRP Rebar: Premium Glass Fiber Reinforced Plastic for Modern Construction
Product Overview
Glass Fiber Reinforced Plastic (GFRP) rebar combines glass fiber reinforcement with thermoset resins to create an alternative to traditional steel reinforcement. Engineered for construction environments where corrosion resistance and structural durability are required, GFRP rebar is used in bridges, marine structures, tunnels, and other concrete applications.

FAQ
What is FRP rebar used for?
FRP rebar is used for concrete reinforcement in bridges, marine structures, tunnels, highways, parking garages, water tanks, wastewater facilities, chemical plants, and seismic retrofitting. It is commonly selected for corrosive and harsh environments.
Why choose FRP rebar over steel rebar?
FRP rebar is non-corrosive, approximately one-quarter the weight of steel, electrically non-conductive, and offers tensile strength up to 600 MPa. It reduces rust-related maintenance and can extend concrete structure service life in aggressive environments.
Does FRP rebar corrode?
FRP rebar is resistant to chlorides, moisture, chemicals, and de-icing salts, making it suitable for coastal bridges, marine structures, wastewater treatment, and aggressive soil conditions.
What sizes are available for FRP rebar?
FRP rebar is available in diameters from 8 mm to 36 mm with tensile strengths from 450–600 MPa depending on diameter. Common lengths are 6 m, 12 m, or custom cut to project specifications.
Is FRP rebar electrically non-conductive?
Yes. FRP rebar provides electrical insulation, making it suitable for MRI rooms, electrical substations, airports, and structures requiring electromagnetic compatibility and worker safety.
Can FRP rebar be used in bridges and highways?
Yes. FRP rebar is used in bridge decks, highway barriers, and concrete exposed to de-icing salts. Its corrosion resistance helps reduce concrete spalling and maintenance.
What is the service life of FRP rebar?
FRP rebar service life depends on resin system, fiber content, environmental exposure, and concrete cover. In well-designed applications, it can provide long-term durability without the corrosion concerns associated with steel.
Is FRP rebar more expensive than steel rebar?
FRP rebar may have higher upfront material cost, but lifecycle cost can be lower due to reduced corrosion maintenance, longer service intervals, and reduced concrete cover requirements in some designs.
