Why use Fiberglass Rebar ?
Corrosion of internal reinforcing steel is one of the main reasons concrete structures deteriorate. Inevitably concrete will crack, creating a direct avenue for chlorides to begin oxidizing the steel rebar. Fiber Reinforced Polymers (FRP’s) are a proven and successful alternative reinforcing that give structures a longer service life.
Concrete near high voltagles and electromagnetic fields can have its internal steel build stray and leakage currents. GFRP rebar is an electrial isolator made from the same materials as polymer insulators.
The aniostropic properties of fiberglass rebar enable TBM and mining equipment to consume concrete in such applications as “soft-eye” openings in deep foundations.
Fiberglass rebar is thermally non-conductive which helps isolate concrete members from thermal effects, such as in the THiN-Wall insuated wall panel building envelop system.
