GFRP

**GFRP** (glass fiber reinforced polymer) is a composite material made by reinforcing a polymer resin with fine glass fibers. The result is lightweight and strong, and it works as a modern alternative to steel reinforcement in concrete. It contains no metal, so it doesn’t rust in marine, humid or chemically aggressive environments. It is also non-conductive and non-magnetic, which suits MRI rooms, laboratories, communication sites and power stations. It comes as rebar, mesh and factory-bent elements, and it is used in roads, bridges, tunnels, marine structures, precast concrete and protective installations. Its elastic modulus differs from steel’s, and it has no yield point, so it must be designed by a licensed structural engineer under the applicable code. Bars can’t be bent on site, so all bends and stirrups are made in the factory to the project plan. Claims such as strength above steel, much lower weight and cost savings come from manufacturers, so verify them against test certificates and local standards before relying on them in design or pricing.
