Description
Crimar Composites GFRP (glass fiber-reinforced polymer) rebar is a corrosion-proof reinforcement for concrete. It never rusts, weighs about one-quarter of steel, offers roughly twice the tensile strength of steel, and is non-conductive and non-magnetic — ideal wherever steel rebar corrodes and fails.
Why FRP Rebar
- Corrosion-proof: immune to chlorides, acids, and alkalis — no rust, no concrete spalling.
- Lightweight: about 1/4 the weight of steel, lowering shipping and handling costs.
- High strength: roughly twice the tensile strength of steel rebar.
- Non-conductive & non-magnetic: ideal for MRI suites, substations, and sensitive facilities.
- Long service life: decades of maintenance-free performance.
Typical Applications
- Bridge decks and barriers
- Seawalls and marine structures
- Water and wastewater treatment plants
- Tunnels and foundations
- Roads and precast elements
