What is GFRP Rebar?
GFRP rebar is a composite material made through a process called pultrusion. It is composed of high-tensile-strength E-glass fibers embedded in a durable polymer resin matrix (typically vinyl ester or epoxy). The outer surface is sand-coated to ensure an exceptional bond with concrete, creating a reinforcement solution that is significantly lighter and more resilient than steel.
Shiv’s Assets Group is a leading exporter of Glass Fiber Reinforced Polymer (GFRP) Rebar from Bharuch, Gujarat, India. Our GFRP rebar is a cutting-edge, non-corrosive, and high-strength alternative to steel, designed to provide superior durability and a longer service life for concrete structures in even the most aggressive environments

GFRP stands for Glass Fiber-Reinforced Polymer is one of the best Rebar used for constructions, FRP stands for Fibre Reinforced Polymer which includes basalt (BFRP) and carbon (CFRP)
GFRP (Glass Fiber Reinforced Polymer) rebar is a composite material made from high-strength glass fibers and a durable polymer resin. You should choose it over steel rebar primarily for its corrosion resistance. Unlike steel, GFRP will not rust, making it ideal for structures exposed to saltwater, chemicals, or de-icing salts. This eliminates expensive maintenance and extends the life of a concrete structure to over 100 years. It’s also significantly lighter than steel, which reduces your shipping costs and simplifies on-site handling.
Yes, in terms of tensile strength, GFRP rebar is typically twice as strong as steel. However, it has a lower modulus of elasticity (it’s more flexible than steel), so it’s essential to follow specific design guidelines to ensure proper structural performance. For applications where corrosion is a concern, GFRP provides superior long-term strength.
GFRP rebar is best suited for projects where its unique properties are a major advantage. These include coastal and marine structures, wastewater treatment plants, bridge decks, and tunnels. It is also perfect for specialized projects like MRI rooms in hospitals and electrical substations due to its non-magnetic and non-conductive properties.
Due to higher fatigue properties, GFRP rebars have higher resistance to cyclical Loads of high intensity, which makes SKD rebars workable during earthquakes
The change in the ambient temperature on the strength of composite reinforcement is practically unaffected. It can be used at temperatures from -70 to +120 degrees Celsius.
Mounting of composite reinforcement is made in the same way as metal. But thanks to the low weight of fiberglass reinforcement, it is possible to mount the rods with plastic clips, and not just a tie wire.
Plastic clips or knitting wire, and also with the help of special plastic fix-clips. Faster and cheaper – plastic ones.
Material is considered to be fire resistant as it doesn’t burn directly and studies show that structures are sustainable during a fire.
The main difference is its weight—it’s about one-quarter the weight of steel, making it much easier and safer to handle. GFRP rebar cannot be bent on-site; all bends, like L-bars or stirrups, must be factory-produced. It is also cut with a diamond-tipped saw, not with shears, to prevent fiber damage. Other installation methods, such as tying, are similar to steel.
