GFRP rebar
Glass Fibre Reinforced Polymer (GFRP) rebar is made of continuous high-strength E-glass fibres in an epoxy matrix. The fibres carry the load; the resin binds them, transfers stress and protects them from the environment.
Sizes
- Diameters 4–40 mm, ribbed profile
- Coils of 70–100 m up to 10 mm diameter
- Straight bars cut to length; bent shapes made at the factory
