Product Description
Our 16mm Glass Fiber Reinforced Polymer (GFRP) rebar is a corrosion-resistant reinforcement option for concrete structures in aggressive environments. Manufactured with E-glass fibers in a vinyl ester resin matrix, this 16mm bar provides a tensile strength above 1,200 MPa and is approximately 73% lighter than equivalent-diameter steel reinforcement. The precise 16mm diameter is ideal for medium to large concrete structures in challenging environments where long-term corrosion resistance is critical.
Suitable for salt-exposed marine construction, chloride-rich swimming pools, chemical-resistant industrial floors, and de-icing salt affected bridge decks, 16mm GFRP rebar does not rust or corrode like steel. This can extend infrastructure service life and reduce maintenance in aggressive environments. Its electrical and thermal non-conductivity makes it a common choice for hospitals, MRI rooms, research facilities, and electrical substations where electromagnetic neutrality is desired.
Each 16mm fiber reinforced bar undergoes rigorous quality testing and is manufactured with either sand-coated or helical-wrapped surface treatments to maximize concrete bond strength. Whether you are building infrastructure for aggressive environments or seeking to reduce lifecycle maintenance, 16mm GFRP reinforcement offers a corrosion-resistant alternative to steel for concrete structures.

Lifecycle Cost-Benefit Analysis: 16mm GFRP vs. Steel Reinforcement
While 16mm GFRP reinforcement typically has a higher initial material cost than steel, lifecycle cost should be evaluated for structures in corrosive environments:
- Reduced Corrosion-Related Repair Costs: Steel-reinforced concrete in aggressive environments may require corrosion repairs over time. GFRP reinforcement can reduce or delay these repair cycles when correctly specified.
- Potential for Extended Service Life: GFRP reinforcement can extend the service life of concrete structures in corrosive environments compared with conventional steel, depending on design, cover, and exposure conditions.
- Reduced Handling and Installation Effort: Lower weight than steel can reduce handling time and equipment needs. Bars can be cut with abrasive wheels rather than hydraulic cutters.
- Transportation Efficiency: Lower weight allows more linear meters per shipment, potentially reducing transport costs and deliveries.
- Seismic Considerations: GFRP reinforcement has different elastic properties than steel; seismic design should follow applicable codes and engineering analysis.
- Insurance Considerations: Project-specific insurance implications should be reviewed with insurers; GFRP is not universally recognized as a premium reduction factor.
Lifecycle cost analysis should be performed on a project-specific basis, considering environment, design life, maintenance assumptions, and discount rates.

Frequently Asked Questions About 16mm GFRP Reinforcement
Q: How do I cut 16mm GFRP rebar on the construction site?
A: 16mm GFRP reinforcement can be easily cut on-site using a standard fiber-cutting wheel on a portable angle grinder. Unlike steel reinforcement, no heavy hydraulic cutters are required. We recommend wearing a dust mask and eye protection during cutting operations. Cuts are clean and require no special treatment after cutting.
Q: Can 16mm GFRP reinforcement be bent on-site like steel rebar?
A: Unlike steel, GFRP reinforcement cannot be bent on-site after manufacturing due to the unidirectional nature of the glass fibers. All bends, hooks, and custom shapes must be factory-formed during production. We offer an extensive catalog of pre-bent configurations with just a 2-week manufacturing lead time. Our engineering team can assist with planning bent bar requirements during the design phase.
Q: Does our crew need special training to install GFRP reinforcement properly?
A: Basic orientation training is strongly recommended for crews working with GFRP reinforcement for the first time. We provide comprehensive online training modules and detailed installation guidelines with every purchase. For projects exceeding 5 tons of reinforcement, our technical support team offers complimentary on-site training sessions and installation supervision for critical structural elements.
Q: What’s the proper method for splicing or joining 16mm GFRP reinforcement sections?
A: 16mm GFRP reinforcement bars can be joined using either specially designed non-metallic mechanical splice couplers or by creating sufficient concrete-bonded overlap as specified in your engineering drawings. Standard lap splice lengths are typically 40-60 times the bar diameter (640-960mm for 16mm bars). Our technical guidelines provide specific overlap requirements based on concrete strength and confinement conditions.
Q: Will local building officials and inspectors approve GFRP reinforcement in my construction project?
A: GFRP reinforcement is recognized in several international and national building codes including IBC, ACI 440.1R-15, CSA S806, and Eurocode provisions. We provide code compliance documentation tailored to your jurisdiction’s requirements and can assist with submittals.
Q: What are the main differences between 16mm glass fiber (GFRP) and 16mm basalt fiber (BFRP) reinforcement options?
A: Our standard 16mm reinforcement uses E-glass fiber for optimal cost-performance balance in most applications. The basalt fiber variant provides approximately 15% higher tensile strength, 10% greater temperature resistance (up to 650°C vs. 580°C for short-term exposure), and marginally improved chemical resistance to some highly alkaline environments. However, the basalt option comes at approximately 20-25% higher cost. For most concrete reinforcement applications, including marine structures and chemical plants, our standard GFRP reinforcement is the recommended and more cost-effective choice.
Q: Can 16mm GFRP reinforcement completely replace steel reinforcement in all concrete applications?
A: While 16mm GFRP reinforcement excels in corrosive environments, it has different engineering properties than steel reinforcement that must be considered during design. Most notably, its lower elastic modulus (55-63 GPa vs. 200 GPa for steel) requires different design approaches for deflection control. GFRP is ideally suited for tension-controlled elements in corrosive environments but may not be the optimal choice for heavily compressed members or where ductility is a primary design consideration. Our engineering team provides free consultations to determine if GFRP reinforcement is suitable for your specific structural application.
Q: How does the concrete cover requirement differ between GFRP and steel reinforcement?
A: GFRP reinforcement may allow reduced concrete cover in some corrosive environments, but cover requirements must follow project-specific design codes and engineering calculations. Do not assume reduced cover without design verification.
Q: Is special concrete mix design required when using 16mm GFRP reinforcement?
A: Standard concrete mix designs used with steel reinforcement are generally compatible with GFRP reinforcement. However, since GFRP bars can’t be bent on-site, extra attention should be paid to concrete workability to ensure proper consolidation around congested reinforcement areas. For highly optimized designs, slight modifications to concrete mix proportions may be beneficial to match the elastic modulus characteristics of the GFRP system.
