Fiberglass rebar, also known as FRP or GFRP rebar, is a composite material made of fiberglass roving and resin. It serves as a superior alternative to steel in concrete reinforcement, offering high tensile strength, corrosion resistance, non-conductivity, and light weight. It is especially beneficial in environments exposed to moisture, chemicals, or de-icing salts. Additionally, its ease of handling and installation helps reduce labor costs and construction time.
