Why Choose Us

Key Features & Benefits

Superior Corrosion Resistance

Unlike steel, GFRP rebar will never rust or corrode — even in harsh chemical, marine, or deicing salt environments. Eliminates spalling and extends structure lifespan by 50+ years.

High Tensile Strength

With tensile strength exceeding 1,000 MPa, our GFRP rebar delivers twice the strength of standard steel rebar at a fraction of the weight, enabling lighter and more efficient structural designs.

75% Lighter Than Steel

At only 1/4 the weight of steel, GFRP rebar dramatically reduces transportation costs, simplifies on-site handling, and accelerates installation — especially in complex formwork.

Non-Conductive & Electromagnetically Neutral

GFRP rebar is electrically non-conductive and non-magnetic, making it the ideal reinforcement for MRI suites, electrical substations, laboratories, and sensitive electronic facilities.

Cost-Effective Lifecycle Savings

While the initial material cost is comparable to epoxy-coated steel, GFRP rebar eliminates future maintenance and repair costs — delivering up to 30% total lifecycle savings in aggressive environments.

ASTM D7957 Certified Quality

Every production batch is tested and certified to meet ASTM D7957 and ACI 440.1R standards, ensuring consistent quality, dimensional accuracy, and traceability for every shipment.

FAQ

Frequently Asked Questions

Is GFRP rebar stronger than steel?
Yes. GFRP rebar has 2–3× higher tensile strength than Grade 60 steel (≥1,000 MPa vs 420 MPa). However, its elastic modulus is lower (40–60 GPa vs 200 GPa), meaning deflection criteria may govern design per ACI 440.1R. For corrosion-critical applications, GFRP is the superior choice.
How does GFRP rebar pricing compare to steel?
While the upfront material cost is typically higher than standard steel, GFRP delivers significant lifecycle savings. In corrosive environments, steel requires epoxy coatings, cathodic protection, and eventual replacement — costs that GFRP eliminates entirely. Typical lifecycle savings of 30–50% in marine, wastewater, and deicing salt applications.
What sizes and lengths are available?
Standard diameters: 10mm, 12mm, 16mm, 20mm, and 25mm. Standard lengths: 6m and 12m. Custom cut lengths and factory-pre-bent shapes are available upon request. Contact us with your project specifications for a tailored quote.
What standards and certifications apply?
Our GFRP rebar is manufactured in compliance with ASTM D7957 (Standard Specification for Solid Round GFRP Bars) and designed per ACI 440.1R (Guide for the Design and Construction of Structural Concrete Reinforced with FRP Bars). We also comply with ISO 9001:2015 quality management standards and can provide CE marking documentation for EU projects.
Can GFRP rebar be bent on site?
No — GFRP rebar cannot be field-bent like steel. Unlike steel, GFRP does not yield plastically. All bends, stirrups, and custom shapes must be factory-manufactured during the pultrusion process. We offer custom bent shapes, stirrups, and mesh panels based on your engineering drawings.
What is the lead time and MOQ?
Lead time: 15–25 days for standard sizes (depending on quantity). MOQ: 500 meters for standard diameters. Sample orders available for qualified projects. Shipping: FOB China ports (Shanghai, Ningbo, Tianjin) with full export documentation including mill certs and third-party inspection reports.
