High-strength solid rods
Pultruded with 65-70% unidirectional glass roving for exceptional tensile strength along the longitudinal axis. Primary applications include soil nails, rock bolts, guy-wire replacements, and marine tie-rods where non-magnetic, non-conductive, and corrosion-proof properties are decisive advantages over steel.
Available sizes
Surface options: smooth, sand-coated, or helically wound — selected to suit bond requirements.

Frequently Asked Questions
What are pultruded FRP round rods used for?
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.
What is the tensile strength of FRP round rods?
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.
Are FRP rods non-magnetic and non-conductive?
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.
Can FRP round rods be used as rebar in concrete?
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.
