Overview
Rods are pultruded with 65–70% unidirectional glass roving, so nearly all of their strength runs along the axis. They serve as soil nails, rock bolts, guy-wire replacements and marine tie-rods, where a non-magnetic, non-conductive rod that cannot rust has the edge over steel.

- Non-magnetic

Values of the isophthalic polyester laminate every datasheet lists. Moduli and strengths are the EN 13706-3 E23 minimums; ILSS is published above the 25 MPa minimum. Transverse strength is much lower than longitudinal, so connections need their own check. Full property table and test methods
Rods are mostly unidirectional roving, so their axial strength and modulus run well above these grade minimums. Ask for measured values for the diameter and resin you need.
Resin options
- Isophthalic polyesterStandard laminate for general structural use. Not fire-retardant.
- Fire-retardant polyesterFor an ASTM E84 Class 1 requirement in mild chemistry; the test report is issued per profile.
- Vinyl esterChemicals, seawater and wastewater; fire-retardant with low smoke.
- PolyurethaneTough matrix for thin walls and impact.
- PhenolicFire-critical enclosed spaces: low flame spread, smoke and toxicity.
All are declared to grade E23. Resin decides chemical and fire performance, not stiffness. Compare resin systems

Questions buyers ask
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 remove the cause of corrosion-induced concrete spalling, which extends the service life of the structure. Bond strength is comparable to deformed steel rebar when surface treatment is specified correctly.
Quote FRP round rods
Send the size, length and quantity, the service environment and the destination. We reply within one business day; a formal quotation follows once the specification and delivery are reviewed.
- Lengths & tolerances
- Catalog sections come in 6 m lengths or cut to your length. Give the piece length and count, say whether ASTM D3917 or EN 13706 tolerances apply, and mark any tighter tolerances, holes or end cuts on the drawing.
- Resin & surface
- Polyester suits general structural use; vinyl ester is the usual choice for chemicals, seawater and wastewater. Tell us the chemicals, concentration, temperature, outdoor exposure, color and any fire requirement, and we will confirm the resin and surface veil.
- Quantity & samples
- Catalog sections ship in 2–4 weeks. Give the trial quantity and the expected repeat demand; minimum quantities and samples are confirmed for the section and resin you choose.
- Documents & delivery
- Each production batch ships with a mill test certificate. Include the destination and target date, and we will quote FOB or DDP with the packing method and shipping schedule.
