Searched for "fiberglass rebar for concrete"? You're likely evaluating corrosion-resistant, non-conductive, and lightweight alternatives to traditional steel rebar in construction projects—especially in aggressive environments like marine structures, bridges, or chemical plants. This guide focuses on identifying top suppliers of GFRP (Glass Fiber Reinforced Polymer) rebar from China, known for high tensile strength (up to 1500MPa), CE certification, customization options (diameter 3–40mm), and competitive pricing. Based on verified supplier data from Alibaba.com, we analyze six leading manufacturers across河北, Jiangxi, and Jiangsu provinces, all offering anti-corrosion solutions with strong delivery performance (on-time rate ≥88%) and customization capabilities including threading, cutting, and bending services. Whether you need large-volume orders or small trial batches, this report delivers actionable insights.

🔍 How to Find High-Quality Products?

The following analysis covers six leading Chinese suppliers of fiberglass rebar for concrete reinforcement, primarily based in Hebei and Jiangxi provinces. These companies specialize in pultruded GFRP/FRP rebars, mesh, and composite bars, with over 80% holding CE certification and 100% on-time delivery records among top performers. Subcategories include standard straight rods, threaded variants, bent configurations, and mesh forms—all designed for durability in corrosive environments.

📋 Horizontal Comparison of Key Parameters

Note: Suppliers use different resin systems and fiber ratios—e.g., Jiujiang Xingli uses basalt for alkali resistance, while Fiberwell integrates carbon fibers for higher stiffness. Shine Universe offers corrugated textures to improve bond strength with concrete, mimicking deformed steel bars.

🔧 How to Use and Maintain?

Fiberglass rebar is best suited for environments where steel would corrode—such as seawater-exposed structures, wastewater treatment facilities, de-icing salt-heavy roadways, and chemically aggressive industrial floors. Unlike steel, GFRP does not conduct electricity or magnetism, making it ideal for MRI rooms, radar stations, and explosive environments.

Application Scenarios

• Bridge Decks: In northern U.S. states using road salts, GFRP prevents spalling caused by rust expansion. Installers must avoid sharp bends (< 15° radius) to prevent delamination.
• Marine Pilings: Used in docks and offshore platforms. Pair with non-metallic ties to eliminate galvanic corrosion.
• Tunnels & Underground Structures: Resists sulfate attack in soil. Ideal for subway systems in coastal cities.
• Swimming Pools & Aquaculture Tanks: Non-reactive with chlorine and saline water. Hebei Tengjun supplies integrated pool shells with embedded FRP mesh.
• Historic Restoration: Lightweight nature reduces load on aging foundations during seismic retrofits.

Installation Best Practices

• Use plastic spacers to maintain cover depth; never weld near GFRP.
• Avoid dragging bars over rough surfaces to prevent fiber abrasion.
• For lap splicing, follow ACI 440.1R guidelines—typically 40–50× bar diameter.
• Do not exceed recommended bend radii (usually >15× diameter).

Maintenance & Longevity

GFRP requires minimal maintenance. Its lifespan exceeds 75 years in most conditions. To maximize durability:

• Inspect annually for surface cracking or UV degradation (apply UV-resistant coating if exposed).
• Clean with mild detergent; avoid abrasive tools.
• Ensure proper concrete cover (≥50mm) to shield from direct sunlight.
• Monitor bond integrity in dynamic loads—replace if debonding occurs.

Unlike steel, there’s no need for cathodic protection or rust inhibitors. However, avoid contact with strong alkaline cleaners during construction cleanup.

❓ FAQ

Are these suppliers covered by Alibaba Trade Assurance?

Yes, all listed suppliers participate in Alibaba Trade Assurance, which protects payments and ensures shipment according to contract terms.

What are typical sample policies?

Most offer free samples under 2 meters, with freight collect. Lead time: 3–7 business days.

Can fiberglass rebar be used in high-temperature environments?

GFRP softens above 180°C. Not recommended for fire-prone areas unless encased in fireproof concrete.

Is installation more complex than steel?

No—same tools apply, but no welding needed. Lighter weight speeds up handling.

⭐ Conclusions and Recommendations

• Low-Cost Mass Production: Choose Lianzhong FRP or Hebei Guangtuo for economical pricing ($1.75–$2.00/m) and reliable delivery.
• High-End Brand Customization: Opt for Fiberwell or Jiujiang Xingli for color-matched, branded, hybrid composites with full OEM support.
• Rapid Trial Orders: Fiberwell and Jiujiang Xingli accept MOQs as low as 200–300m with 10-day delivery.
• Mixed Procurement Strategy: Use Shine Universe for threaded connectors and Lianzhong for straight runs to balance cost and function.

📋 Due Diligence / Factory Audit Checklist

• Verify CE or ISO certifications via third-party platforms
• Request video audit of pultrusion line operation
• Confirm resin type (epoxy vs. vinyl ester) and fiber content
• Test sample for tensile strength and bond adhesion
• Negotiate payment: 30% deposit, 70% against BL copy
• Require test reports per ASTM D7205 or CSA S807
• Clarify warranty: minimum 10-year performance guarantee
• Agree on packaging: wooden pallets with moisture barrier
• Define penalties for late delivery (>5%)
• Establish after-sales contact for technical queries
