What are GFRP rebars?
GFRP rebars are Glass Fiber Reinforced Polymer bars made from high-strength glass fibers and resin. They are lightweight, non-corrosive, and designed to replace traditional steel rebars in concrete construction, offering long-lasting durability.
Why choose GFRP over steel?
Unlike steel, GFRP rebars never rust, making them perfect for coastal and chemical environments. They are also 2–3 times stronger in tensile strength, one-fourth the weight of steel, and reduce life-cycle maintenance costs significantly.
Where can GFRP rebars be used?
GFRP rebars are widely used in bridges, highways, tunnels, ports, metro systems, and industrial plants. They are especially effective in areas exposed to moisture, saltwater, or aggressive chemicals where steel quickly deteriorates.
How long do GFRP rebars last?
With zero corrosion and high durability, GFRP rebars can extend the service life of structures to over 100 years. This makes them a sustainable choice that reduces costly repairs and ensures long-term reliability for critical infrastructure.
Do GFRP rebars affect concrete curing?
No, GFRP rebars are fully compatible with standard concrete mixes and curing processes, ensuring seamless use in construction.
Are GFRP rebars as strong as steel?
Yes. GFRP rebars have a tensile strength 2–3 times higher than steel, while being only one-fourth the weight.
How are GFRP rebars delivered and handled?
GFRP rebars are lightweight and easy to transport, handle, and cut on-site. This reduces logistics costs and makes installation quicker and safer.
Do GFRP rebars require special tools for cutting or bending?
No heavy equipment is required. Straight GFRP rebars can be cut with simple tools like diamond blades, while bent shapes are manufactured in controlled facilities for accuracy.
Are GFRP rebars safe for electrical or MRI facilities?
Yes. Since they are non-conductive and non-magnetic, GFRP rebars are perfect for hospitals, power plants, and facilities where electromagnetic neutrality is important.
Do GFRP rebars meet construction standards?
Yes. Infrabond Composites manufactures rebars that comply with international standards like ASTM, ACI, and Indian guidelines for FRP reinforcements.
Can GFRP rebars be cut and bent like steel?
GFRP rebars can be cut using standard tools like diamond blades, but unlike steel, they are supplied in straight or pre-bent shapes since they cannot be bent on site.
Are GFRP rebars cost-effective?
While initial cost may be slightly higher than steel, GFRP rebars eliminate corrosion-related repairs, making them far more cost-effective over the structure’s lifetime.
Are GFRP rebars safe for all types of construction?
Yes, GFRP rebars are safe and widely accepted in infrastructure projects worldwide. They are non-conductive, non-magnetic, and deliver long-term structural reliability.
Do GFRP rebars bond well with concrete?
Absolutely. GFRP rebars have specially designed surface textures that ensure strong bonding with concrete, providing stability and strength in reinforced structures.
Can GFRP rebars be used in water-related structures?
Yes, they are ideal for marine and water infrastructure like ports, jetties, and dams because they are 100% resistant to corrosion from moisture and saltwater.
Are GFRP rebars environmentally friendly?
Yes, they are a sustainable alternative to traditional reinforcement. Their long service life reduces repair cycles, saving resources and lowering the overall carbon footprint.
