GFRP Rebars & GFRP Bars for Infrastructure and Construction
Corrosion-free. Lightweight. High Strength. An advanced alternative to traditional steel rebar for long-lasting, high-performance infrastructure.
What Is GFRP Rebar?
Glass Fiber Reinforced Polymer (GFRP) rebar is an advanced non-metallic reinforcement solution engineered to replace traditional steel reinforcement in modern concrete structures.
Manufactured using high-strength glass fibers embedded within a durable, corrosion-resistant polymer matrix, GFRP reinforcement bars belong to the family of composite rebars and deliver superior durability, lightweight performance, and long-term structural reliability.
Unlike conventional steel, corrosion resistant rebars made from GFRP do not rust, degrade, or chemically react with moisture, salts, or aggressive agents. This makes them highly suitable as marine construction rebars, as well as for coastal infrastructure, tunnels, wastewater facilities, and underground projects.
As advanced FRP reinforcement and non-metallic reinforcement bars, GFRP rebars are increasingly specified for highways, flyovers, and bridge reinforcement materials where durability, low maintenance, and extended service life are critical.
With a high strength-to-weight ratio and minimal lifecycle maintenance requirements, GFRP rebar significantly reduces long-term ownership costs while enhancing the performance and sustainability of concrete infrastructure—making it a future-ready solution for resilient construction.
What Are GFRP Bars Used For?
Glass fiber reinforced polymer rebar (GFRP rebar) is a next-generation, non-metallic reinforcement solution widely used in modern concrete construction. These corrosion resistant rebars offer high tensile strength, lightweight handling, and long-term durability, making them a superior alternative to traditional steel reinforcement in demanding infrastructure environments.
Roads, Highways & Pavements
GFRP reinforcement bars are extensively used in rigid pavements, highways, expressways, and concrete road projects where corrosion resistance, crack control, and extended service life are critical. These composite rebars reduce maintenance costs and improve pavement durability.
Bridges, Flyovers & Bridge Decks
As advanced bridge reinforcement materials, GFRP bars prevent deterioration caused by moisture, de-icing salts, and heavy traffic loads. Their corrosion-free performance ensures long-term structural integrity and lower lifecycle costs for bridges and flyovers.
Tunnels & Underground Construction
In tunnels, metro rail systems, basements, and underground utilities, FRP reinforcement provides durable, non-corrosive support in confined and moisture-rich environments where conventional steel rebars typically fail over time.
Marine & Coastal Structures
Marine construction rebars made from GFRP are ideal for ports, jetties, seawalls, coastal bridges, and waterfront developments exposed to saltwater, humidity, and aggressive marine conditions that rapidly corrode steel.
Industrial & Chemical Facilities
Composite rebars are widely used in chemical plants, wastewater treatment facilities, and industrial floors where resistance to chemicals, moisture, and harsh operating environments is essential for long-term performance.
Power, Energy & Sensitive Structures
Non-metallic reinforcement bars with non-conductive and non-magnetic properties are preferred for power plants, substations, MRI rooms, data centers, and energy infrastructure requiring electromagnetic neutrality and safety.

Advantage of GFRP Rebar Over Steel
GFRP (Glass Fiber Reinforced Polymer) rebar is a next-generation composite rebar engineered to outperform conventional steel reinforcement in modern infrastructure applications.
One of the most critical advantages of GFRP reinforcement bars is their role as corrosion resistant rebars. Unlike steel, GFRP does not rust or degrade when exposed to moisture, salts, or aggressive chemicals—making it ideal for bridge reinforcement materials, marine construction rebars, coastal infrastructure, and road construction projects.
As non-metallic reinforcement bars, GFRP rebars are approximately one-fourth the weight of steel, allowing easier transportation, faster installation, and reduced labor costs. Despite their lightweight nature, they deliver high tensile strength, excellent fatigue performance, and electromagnetic neutrality.
In summary, GFRP rebar offers a durable, low-maintenance, and sustainable alternative to steel reinforcement, significantly extending the service life and long-term performance of concrete structures across infrastructure sectors.
