GFRP Rebar
GFRP Rebar, or Glass Fibre Reinforced polymer, is a modern construction composite rebar. It is a substitute for steel rebar. GFRP bars have many advantages, such as corrosion resistance, stronger, lighter, cheaper, non-conductive, and cost-effective construction material. Unlike steel rebars, GFRP rebars do not rust, and Corrode is compatible with water and chemicals. GFRP is two times stronger and ¼ lighter than traditional steel bars. It makes the construction lighter and stronger.

Yes, you can use MRG GFRP Rebars together with metal rebars in some cases where it is necessary.
Composite reinforcement is fire resistant up to 600 degrees Celsius. Once the temperature exceeds 600 degrees Celsius, the compound that binds the composite reinforcement fibers softens. Composite reinforcement does not burn directly, and studies show that structures are sustainable during a fire.
No, as the mechanical properties of GFRP Rebars are elastic, thus it does not allow you to bend the material on site. However, you can get your desired bend/curved elements prefabricated as per your requirement.
