Reduction low price and significant budget savings
Metal or Fiberglass
Almost any construction novelty is undergoing the process of adaptation to the market with some snags. The fact is that builders have not sufficiently studied composite reinforcement, so manufacturing companies are introducing slightly different production technologies, which is why GFRP rebars do not always turn out the way they should.

Frequently Asked Question
What are Straight GFRP Rebars?
Straight GFRP Rebars are Glass Fiber Reinforced Polymer reinforcement bars used as an alternative to steel rebars in reinforced cotncrete, offering high strength and complete corrosion resistance.
Can GFRP rebars be bent on-site?
No. GFRP bars cannot be bent on-site without damaging fibres. Where bends are required, factory-formed Bent GFRP Rebars should be used.
Do GFRP rebars corrode or rust over time?
No. GFRP is 100% corrosion-proof because it contains no metal. It does not rust, react with salt, or degrade in moisture-heavy environments.
Are GFRP rebars stronger than steel?
Yes. GFRP rebars provide tensile strength up to 3× higher than mild steel while being 4× lighter.
Are GFRP rebars fire-resistant?
GFRP does not melt at normal construction temperatures. For fire-critical applications, design codes specify appropriate cover thickness.
