High strength alternative to conventional steel rebar
FRP Rebars are made from high strength glass fibres along with an extremely durable vinyl ester resin. The glass fibre imparts strength to the rod while the vinyl ester resin imparts excellent corrosion resistance properties in harsh chemical and alkaline environments. FRP Rebar significantly improves the longevity of civil engineering structures where corrosion is a major factor.
Available in 4mm, 6mm and 8mm diameters, supplied in 3m lengths.
Uses
- Architectural concrete and Glassfibre Reinforced Concrete (GRC)
- Concrete exposed to de-icing salts
- Applications subjected to other corrosive agents
- Applications requiring low electric conductivity or electromagnetic neutrality
- Tunnelling /boring applications requiring reinforcement of temporary concrete structures
- Weight sensitive structures
- Thermally sensitive applications
Advantages
- Non-corrosive
- Tensile strength is more than twice that of steel
- Non-metallic and non-conductive
- Consistent modulus of elasticity
- Deformation patterns are the same as with steel
- Four times lighter than steel
- Coefficient of thermal expansion more similar to concrete than that of steel
