Benefits of FRP rebar
- Excellent corrosion resistance. GFRP rebar will not rust, even in the harshest environments. Unlike steel rebar, FRP rebar ensures a longer lifespan and minimizes maintenance needs.
- Highly Chemical Resistant. Fiberglass rebar resistant to salt ions, acids, chemicals, and the inherent alkalinity of concrete. This is important when you build concrete structures in coastal areas near oceans, seas, rivers and lakes.
- Lightweight. FRP rebar is significantly lighter than steel, facilitating easier handling and installation. For example, composite rebar can weigh up to 75% less than its steel counterpart, resulting in lower transportation and labor costs.
- High Strength. GFRP rebar have high tensile strength, providing reliable reinforcement for concrete and enhancing the durability of structures. The tensile strength of fiberglass rebar can be up to twice that of steel, making it an excellent choice for high-stress applications.
