Fiberglass reinforcement, also known as glass fiber reinforced polymer (GFRP) rebar, is a lightweight, non-corrosive, and non-conductive material used to strengthen concrete. It's a popular alternative to steel rebar in many construction projects. Properties Lightweight GFRP rebar is much lighter than steel rebar, making it easier to transport and place. Non-corrosive GFRP rebar is resistant to rust and corrosion, which can extend the life of a structure. Non-conductive GFRP rebar doesn't conduc
