GFRP rebar for concrete reinforcement

Glass fiber reinforced polymer rebar is specified where steel reinforcement corrodes or where it must not conduct or be magnetic: bridge decks and barriers treated with de-icing salt, seawalls and wharves, tunnel boring machine soft-eyes, MRI suites, substations and slabs on grade. This page maps the uses to the rebar product and lists the standards and bar-schedule details to put on the order.

GFRP rebar for concrete reinforcement in brief

GFRP rebar is used in bridge decks and barriers, marine and splash-zone concrete, tunnel soft-eyes that a TBM cuts through, MRI and electrical rooms that need non-magnetic reinforcement, slabs on grade and precast. Buyers specify the bar schedule by size, length and bent shape, the surface type, the specification (ASTM D7957 in North America) and the design code (ACI 440.11-22), and request the lot test reports. pultrx quotes GFRP rebar and mesh from the Henan Zhongsheng factory against the bar schedule.

Order requirements

What to specify

Put these items on the RFQ so the factory quotes the same product the project drawing describes.

  1. 01Bar schedule: size designation, straight lengths, quantity per size and every bent shape with dimensions.
  2. 02Specification the bar must meet (ASTM D7957 or the project specification) and the lot test reports required.
  3. 03Surface type: sand-coated, helically wrapped or ribbed, and bond requirement if the design code states one.
  4. 04Bar diameter definition (nominal vs measured) so the schedule and the delivery agree.
  5. 05Mesh: panel size, bar size and spacing in both directions, and the joining method.
  6. 06Design code the engineer used (ACI 440.11-22, CSA S806 or project code) so the bar properties quoted match the design assumptions.
  7. 07Packaging, bundling, labeling by size and the destination port.

Standards and documents

Documents buyers cite

Named so the RFQ can refer to them. Citing a standard does not establish that a quoted product conforms to it; conformity, tests and evidence are agreed in the quotation.

ASTM D7957 / D7957M
Standard specification for solid round GFRP bars for concrete reinforcement; cite it for North American projects and request the lot reports for the quoted bars.
ACI 440.11-22
Building code requirements for structural concrete reinforced with GFRP bars; the design engineer applies it and states the assumed bar properties.
GFRP rebar vs steel rebar guide
This site's summary of the code scope, seismic limits and site rules for GFRP rebar, with public sources.

Where GFRP rebar is specified

  • Bridge decks, approach slabs and traffic barriers exposed to de-icing salt.
  • Seawalls, wharves, piers and any splash-zone concrete.
  • Tunnel soft-eyes: GFRP cages the TBM can cut through without stopping.
  • MRI suites, substations, induction furnaces and other areas that need non-magnetic, non-conductive reinforcement.
  • Slabs on grade, parking structures and precast where steel corrosion drives maintenance cost.
  • Water and wastewater tanks and channels.

Design and site rules that differ from steel

GFRP bars have a higher tensile strength and a lower modulus than steel, do not yield, and cannot be bent on site: bent shapes are made in the factory before the resin cures. The design code limits where GFRP may be used (ACI 440.11-22 excludes some seismic categories and fire-rated members) and sets different deflection and crack-width rules. The rebar comparison guide and the cutting and bending guide on this site set out these rules with their sources.

What to send with the enquiry

The bar schedule with bent-shape drawings, the specification and design code, the surface type, the test reports required and the destination. The quotation names the bars supplied, the surface, the tests performed on each lot and the reports issued.

FAQ

Questions buyers ask

Can GFRP rebar be bent on site?
No. The resin is cured, so the bar cannot be bent after manufacture. Bent shapes are produced in the factory before cure and must be on the bar schedule.
Is GFRP rebar supplied to ASTM D7957?
Bars are quoted against ASTM D7957 or the project specification named on the RFQ, with the lot test reports stated in the quotation. No blanket conformity is claimed for a catalogue product.
Which sizes are available?
The rebar product page lists the catalogue size designations. Confirm the diameter definition and the required sizes on the RFQ; availability is established in the quotation.
Does pultrx supply rebar mesh as well as bars?
Yes. Mesh panels are quoted by panel size, bar size and spacing in both directions and joining method, on the GFRP rebar page.
