100% corrosion-proof
Immune to moisture, de-icing salts, chlorine, and saltwater. Designed for a 100-year service life — no rust, ever.
Factory opening soon · Yuma, Arizona
Pultrax makes GFRP fiberglass rebar in Yuma, Arizona — 4× lighter than steel, 2.4× stronger in tension, and 100% immune to corrosion. Serving Arizona, Southern California, Nevada, and the Southwest. Register now to be first in line when the plant opens.
Launch markets
These are the two places steel reinforcement fails first in the Southwest — and where GFRP pays for itself on day one.
Driveways · Patios · Slabs · Sidewalks
Replace wire mesh and steel bar in slabs on grade. No rust staining, no spalling at cracks, and bars one worker carries by the bundle. Cut with the grinder you already own.
Gunite shells · Saltwater pools · Pool decks
Chlorine and saltwater destroy steel rebar from inside the shotcrete. GFRP is 100% immune and non-conductive — built for pools, spas, and the decks around them.
Why GFRP
Moisture, salts, and pool chemicals penetrate concrete and attack steel from the inside — cracking and spalling follow. GFRP is glass fiber and resin: there is nothing in it that can rust.
Immune to moisture, de-icing salts, chlorine, and saltwater. Designed for a 100-year service life — no rust, ever.
A 20 ft #3 bar weighs 2.2 lb. One worker carries a bundle — faster layout, less fatigue, easier on your crew in Yuma heat.
145 ksi vs 60 ksi for Grade 60 steel — with ACI 440.11-22 and ASTM D7957 standards behind it.
Cuts with an angle grinder or recip saw. Zip-tie instead of wire-tie. No torch, no rebar cutter, no special tools.

Performance data
| Property | Pultrax GFRP | Steel (Grade 60) |
|---|---|---|
| Tensile strength | ~145 ksi | 60 ksi |
| Weight (#3 bar) | 0.11 lb/ft | 0.38 lb/ft |
| Corrosion resistance | 100% immune | Corrodes in 20–25 yrs |
| Design service life | 100 years | 25–40 years (corrosive) |
| Fatigue cycles | 420,684 | 23,162 |
| Electrical conductivity | None (inert) | Conductive |
| Lifetime cost of ownership | Far lower — zero corrosion repairs | Spall repairs, resurfacing, replacement |
| MRI / RF transparent | Yes | No |
What it costs
Forget per-ton comparisons — a ton of GFRP holds 3.4× more bars than a ton of steel, so tons tell you nothing. Compare the way you build: bar for bar, crew-day for crew-day, and over the life of the concrete.
Per bar
Competitive
Bar for bar, GFRP is competitive with steel at the yard — the material line of your bid doesn't move.
Installed
Often less
70% lighter bars, smaller crews, no crane, zip ties instead of wire, grinder cuts instead of a rebar cutter — the labor and equipment lines drop on day one.
Over its life
Much less
Steel's real price arrives years later: spalled slabs, rust-stained decks, repairs, early replacement. GFRP never spalls and never rots — you buy the concrete's full life the first time.
Pricing depends on bar size, volume, and freight, and is confirmed in a written quote — we don't publish price lists.
Proven in the field
Bridge · North Carolina
World's largest all-GFRP bridge: 3,200 ft over open saltwater, zero steel, designed for 100 years. Won two 2025 PCI Design Awards.
Seawall · Florida
FDOT's largest GFRP project — over 1 million linear feet of GFRP rebar protecting the coast highway from ocean erosion.
Hospital · Maryland
GFRP's non-magnetic foundations keep signal interference under 0.5 dB — the gold standard for MRI construction.
Questions
Yes. ACI 440.11-22 is a full building code for GFRP-reinforced concrete, referenced alongside ACI 318, and the material specification is ASTM D7957. Departments of transportation across the country — Florida, Minnesota, Ohio, North Carolina — already build bridges with it. Your engineer or building department can design and approve with it directly.
Competitive, bar for bar — and ignore per-ton comparisons, because a ton of GFRP contains 3.4× more bars than a ton of steel. Installed, GFRP often costs less: lighter bars, smaller crews, zip ties, grinder cuts. And over the life of the concrete it costs far less, because it never spalls or rots — no rust repairs, no early replacement. Exact pricing is confirmed at quote.
Yes — easier than steel. It cuts with an angle grinder or recip saw, ties with zip ties instead of wire, and a laborer carries a whole bundle. No torch, no rebar cutter, no iron workers.
No — tight bends and stirrups are factory-made shapes you order with your straight bar. Smaller diameters like #3 do flex elastically to gentle curves, which is exactly what pool shells need.
We're setting up the plant in Yuma, Arizona now. Register your interest and we'll contact you before launch — registered projects get first allocation and early pricing.
Yes — top to bottom. American-made E-CR glass fiber from Columbia, South Carolina; US-produced resin; pultruded into bar at our plant in Yuma, Arizona. That domestic chain supports Build America, Buy America compliance on federally funded work, with origin documentation on every lot. More on the supply chain →
We serve a roughly 750-mile freight radius from Yuma: Arizona, Southern California, Southern Nevada, New Mexico, Utah, and El Paso. At launch you can also will-call at the Yuma plant. Freight is quoted with your order — and because GFRP is 70% lighter than steel, it's usually a smaller line than you're used to.
Yes — as factory-made shapes ordered together with your straight bar (GFRP can't be field-bent). Seven shape families cover corners, stirrups, hairpins, and custom details. See the product page →
