GFRP (Glass Fiber Reinforced Polymer) rebar is an alternative to traditional steel reinforcement used in concrete. Made from high-strength fiberglass and resin, it provides excellent corrosion resistance, lightweight handling, and long-term durability.
At GTOFRP, we supply high-quality GFRP rebar designed to outperform steel in demanding environments such as coastal, marine, and industrial projects.
Standard GFRP rebar price per kg (2025): $3.00 – $6.00 USD depending on diameter and grade.
Bulk orders for infrastructure projects can bring prices down closer to $2.80/kg.
Specialty corrosion-resistant grades may cost higher.
For updated bulk pricing, check GTOFRP Rebar Catalog.
#3 (10mm) GFRP rebar: $1.50 – $1.80 per foot.
#4 (12mm) GFRP rebar: $2.00 – $2.50 per foot.
#5 (16mm) GFRP rebar: $2.80 – $3.50 per foot.
Compared to steel, GFRP rebar costs 20–40% more upfront but delivers 50+ years of service life with minimal maintenance.
| Feature | Steel Rebar (2025) | GFRP Rebar (2025) |
