GRP round rods are made with thermoset polyester resin reinforced with glass fibers. Surface adhesion is improved by a helicoidal groove produced without cutting the surface or any fibers and therefore there is no reduction in the mechanical characteristics in the axial direction. Reduction of such characteristics is typical for other similar products and is a result of cutting the reinforcing glass fibers. GRP rods are utilized mainly for the fabrication of cages or as nails or anchoring systems (active and passive). 

Tests can be performed according to ACI 440, CNR DT203/206. Procedures for designing, executing and controlling structures in concrete reinforced with glass reinforced composite rods, and various other local codes. Please contact ATP Technical Department for specific codes and applications.
