GFRP Rebar
High-Strength, Lightweight GFRP Rebar Designed for Demanding Infrastructure and Marine Applications
GFRP Rebar (Glass Fiber Reinforced Polymer Rebar) is a high-performance, non-metallic reinforcement solution made from continuous glass fibers embedded in a polymer resin matrix. It is specifically designed to replace traditional steel reinforcement in concrete structures, providing enhanced durability and reliability.
Unlike steel, GFRP Rebar does not rust, corrode, or conduct electricity, making it ideal for use in aggressive environments such as marine, coastal, chemical, and industrial settings. Its non-conductive nature also makes it suitable for areas sensitive to electromagnetic interference.
GFRP Rebar offers exceptional tensile strength while being significantly lighter than steel, making transportation, handling, and installation more efficient. Its superior strength-to-weight ratio reduces structural load without compromising performance.
Engineered for modern infrastructure needs, GFRP Rebar delivers long-term durability, reduced maintenance costs, and an extended service life for reinforced concrete structures. It is a future-ready solution for projects demanding corrosion resistance, sustainability, and structural integrity.

Key Features & Benefits :
1. High strength-to-weight ratio
- Despite its lightweight nature, GFRP rebar offers superior tensile strength compared to steel rebar of the same diameter.
- It has a high strength-to-weight ratio, allowing it to withstand high loads and stresses.
- In some cases, GFRP rebar can withstand more than double the force of steel in tension-heavy applications.
2. Corrosion resistance
- GFRP rebar does not rust or corrode when exposed to moisture, salts, or chemicals, making it ideal for coastal environments, bridges, tunnels, chemical plants, and marine structures
- This eliminates the need for additional protective measures like coatings or treatments required for steel rebar.
- It extends the service life of concrete structures significantly, potentially lasting 100 years or more compared to steel’s 15-25 years in harsh conditions.
3. Lightweight
- GFRP rebar is significantly lighter than steel rebar (approximately 75-80% lighter), making it easier and faster to transport, handle, and install.
- This can reduce labor costs and potential injuries on site.
- The lighter weight also reduces the overall dead load of the structure, allowing for potential weight reduction in the concrete itself.
4. Electrical and thermal insulation
- GFRP rebar is non-conductive to electricity, making it suitable for applications where electromagnetic neutrality is critical, such as MRI facilities, power plants, and structures near sensitive electronic equipment or in rail corridors where stray currents can be a concern.
- GFRP rebar also has low thermal conductivity, which can help prevent thermal bridging and improve energy efficiency in buildings.
5. Durability and longevity
- GFRP rebar’s excellent corrosion resistance directly translates to a longer service life for concrete structures, minimizing the need for costly repairs and replacements.
- GFRP rebar also exhibits excellent fatigue resistance, making it more durable under cyclic loading compared to steel.
- Structures reinforced with GFRP rebar remain crack-free and structurally sound, reducing the risk of corrosion-induced expansion and spalling.
6. Cost-effectiveness (long-term)
- While the initial cost of GFRP rebar may be higher than steel, its superior durability, corrosion resistance, and reduced maintenance requirements often lead to lower lifecycle costs and a greater return on investment over the long term.
- Reduced transportation and installation costs due to lighter weight further contribute to overall savings.
7. Environmental sustainability
- GFRP rebar production has a lower carbon footprint compared to steel.
- Its longer lifespan reduces the need for frequent replacements, contributing to resource conservation and a more sustainable construction process.
