FRP Round Rods

Pultruded FRP solid round rods are used for soil nails, rock bolts, ground anchors, marine tie-rods, FRP rebar in concrete, electrical insulator cores, antenna masts, and tooling shafts. The combination of high tensile strength, non-magnetic and non-conductive properties, and zero corrosion makes them the standard choice in environments where steel cannot survive.

Pultruded FRP round rods with 65–70% unidirectional glass roving have axial tensile strength of 700–1100 MPa — significantly higher than mild steel (400 MPa) on a strength-per-weight basis. Modulus is 40–55 GPa. Specific values depend on resin system and fiber loading; full datasheets available on request.

Yes. Glass-reinforced pultruded FRP rods are electrically non-conductive (volume resistivity > 10¹² Ω·cm), magnetically transparent, and RF-transparent. This makes them the preferred choice for MRI room reinforcement, transformer spacers, electrified railway tie-rods, and antenna structural elements where steel would short, arc, or distort EM fields.

Yes. Sand-coated or helically wound FRP rods are used as non-corrosive concrete reinforcement, particularly in marine structures, bridge decks, parking decks, and chemically aggressive slabs. They eliminate corrosion-induced concrete spalling, extending service life to 75+ years. Bond strength is comparable to deformed steel rebar when surface treatment is specified correctly.
