Fiber Reinforced Polymer (FRP) Rebar, also known as composite rebar, is a cutting-edge non-metallic reinforcing bar manufactured via continuous pultrusion and winding molding technology, composed of high-performance continuous reinforcing fibers (glass fiber, carbon fiber or aramid fiber) embedded within thermosetting resin matrix including polyester, vinyl ester and epoxy resin. Featured with spiral ribbed or sand-coated outer surfaces as shown in the product picture, the special textured design maximizes mechanical interlock and bonding friction between FRP rebar and poured concrete, solving the slippage defect common to smooth-surface reinforcing materials.
Classified by raw material, mainstream FRP rebar falls into three categories: GFRP (Glass Fiber Reinforced Polymer) rebar as the most cost-effective general type (black/green finished specimen in the attached image), CFRP (Carbon Fiber Reinforced Polymer) rebar with ultra-high tensile modulus for heavy-load engineering, and AFRP (Aramid Fiber Reinforced Polymer) rebar customized for anti-fatigue and impact-resistance projects. Our SPARE-series FRP rebar strictly complies with global authoritative industrial standards such as ASTM D7957, ACI 440.1R, ISO10406 and CE certification specifications, available in customized diameters ranging from 6mm to 40mm to satisfy differentiated reinforcement requirements across construction sectors.
