Composite Rebar - GFRP (Glass Fiber Reinforced Polymer) - is a non-metallic reinforcement made from glass fibers soaked in a resin matrix (.e.g. Vinyl ester or epoxy) It doesn’t corrode and it’s 4 times lighter dan steel.

One of the benefits of composite rebar is its low weight. Lightweight composite rebar is up to 75% lighter than steel. Because of this, one truckload of composite rebar can replace roughly nine truckloads of steel. This lowers the transportation costs, reduces emissions, and simplifies on‑site handling. Workers can move longer lengths by hand, without heavy lifting equipment.

Glass Fiber Reinforced Polymer (GFRP) composite rebar, offers exceptionally high tensile strength, two to three times higher than standard steel. GFRP Composite Rebar is up to 75% lighter than steel, making it a lot easier to transport and handle. This combination of high strength and low weight allows composite rebar to withstand heavy loads and strong environmental forces. It enables the design of highly resilient, long-lasting structures that maintain their performance for over 100 years.

At the moment, the initial purchase price of composite rebar may be slightly higher or the same price, but the total cost of ownership (TCO) in construction is lower. Because composite reinforcement does not rust, they eliminate the need for expensive maintenance and structural repairs. Over a 10-year period, maintenance savings can cut repair costs by 60–80%. When you combine the lower transport and installation costs, composite rebar becomes the most cost-effective long-term solution.

Steel requires a thick concrete cover (40–50 mm) to delay corrosion. Because composite rebar is naturally 100% corrosion-resistant, this protective barrier is no longer needed. Engineers can safely reduce the thinner concrete cover to just 15-20 mm without compromising structural integrity. This enables slimmer structural elements and up to 20% reduction in total concrete volume. Using less concrete lowers material costs and helps to reduces your carbon footprint.

Steel is a strong conductor of heat and cold, and creates thermal bridges that reduce a building’s energy performance. Composite rebar has a very low thermal conductivity and eliminates these thermal bridges entirely. By replacing steel with composite reinforcement, the building maintains a far more stable indoor climate. Spaces stay cooler during hot summers and retain warmth in the winterperiods. The result is lower energy consumption in the building.

GFRP is 100% corrosion‑resistant, meaning it will not rust from de‑icing salts, moisture, or harsh weather. This prevents concrete rot and extends the bridge deck’s lifespan to over 100 years without degradation. The long‑term maintenance cost reduction can go up 60% to 80%. Installation is significantly faster. This reduces traffic disruption and road closures by 20% to 30%. The material’s durability and maintenance‑free performance also contribute to a substantially lower carbon footprint, making it a future‑proof choice for modern bridge rehabilitation
