GFRP rebar FAQs

1. Why is there a need for GFRP rebar?

Traditional steel rebars are susceptible to corrosion, which compromises the structural integrity of concrete over time. This corrosion leads to premature deterioration, increased maintenance costs, and reduced service life of concrete structures. 

GFRP (Glass Fiber Reinforced Polymer) Rebar emerges as a game-changing alternative, effectively addressing the challenges posed by traditional steel rebars. With its corrosion-resistant nature, superior strength, and lightweight handling, GFRP Rebar revolutionizes structural reinforcement, ensuring longer-lasting, cost-effective, and eco-friendly concrete structures. GFRP Rebar is versatile and can be used in a wide range of applications, including bridges, highways, buildings, marine structures, and more. Its excellent mechanical properties and non-magnetic nature make it suitable for diverse projects. GFRP Rebar is widely approved by major building codes and standards, making it a reliable and compliant option for construction projects worldwide.

It can be seamlessly integrated into traditional construction practices.

2. What are FRP and GFRP?

Fiber-reinforced polymer (FRP) is a composite material of a polymer matrix reinforced with fibers.  FRP stands for Fibre Reinforced Polymer which includes basalt (BFRP), carbon (CFRP), and Glass Fiber-Reinforced Polymer (GFRP). Fiber-reinforced polymer is useful in terms of corrosion protection because it helps prevent corrosion due to force application and deformation such as stress corrosion cracking. The fibers are usually glass (in fiberglass also known as GFRP), carbon (in the carbon-fiber-reinforced polymer), aramid, or basalt. The polymer is usually epoxy, vinyl ester, or polyester thermosetting plastic. 

It is commonly used in industries such as aerospace, construction, and marine to build structures that require added resistance to force in order to prevent deformation.

2. What is GFRP rebar- FiBAR®?

FRP (Fiberglass Reinforced Polymer) Rebar is a spiral-wrapped structural reinforcing rod made from a combination of fiberglass roving and resin. While it may surprise you FRP rebar has been successful for over thirty years in the US, Canada, and other places. Fiberglass Reinforced Polymer (FRP), or fiberglass, is a composite consisting of a polymer resin matrix reinforced by glass fibers and then shaped into bars, we call it FiBAR®. When compared to metals, FRP is still your best bet.

GFRP rebars are NOW IN INDIA!

GFRP rebar FiBAR® has a high tensile strength which means they are at least 2x stronger than traditional steel of the same diameter. This allows you, in some cases, to replace the diameter of steel with one size smaller diameter of FiBAR® without any loss of performance. Since FiBAR® is 100% non-corrosive and has a life of over 2x that compared with steel reinforcement bars, this makes it easy to choose. While deciding between GFRP rebar and steel rebars, the durability of FiBAR® will take over the other. As the density of glass fiber reinforcement is only 1900 kg/cubic meter, it makes FiBAR® about 4x lighter than the conventional reinforcement bars making it easy to handle, transport, and faster construction process.

3. What are the sizes available for FiBAR®?

We manufacture and supply FiBAR® of diameters 4, 6, 8, 10, 12, 16, 20, and 25mm.

​

​

4. How do you transport FiBAR®?

GFRP rebar, FiBAR® is typically transported in coils of 100-200m for diameters up to 12mm, while diameters beyond 12mm are transported according to the vehicle length, usually 6m long bars. These transportation methods are designed to ensure easy handling and storage of the product during transit. However, it is important to handle and transport GFRP rebar with care to prevent damage or deformation. Proper packaging and securing of the product are essential to ensure that it arrives at its destination in good condition.

5. How to cut FiBAR®?

When it comes to cutting GFRP rebar or reinforcement bars such as FiBAR®, it is essential to handle the product with care to avoid injury or damage. To cut FiBAR®, you should first open the packaging completely, being careful not to force the product out too quickly, as the elastic energy in the material can cause it to snap back suddenly and cause injury.

It's worth noting that FiBAR® is a thermoset material that cannot be bent post-curing, so cutting is the best way to shape it to the required length. On-site cutting can be done using carbide or diamond-coated blades, which are specifically designed to handle the high strength and durability of GFRP rebar or reinforcement bars like FiBAR®.

6. How to install FiBAR®?

When it comes to installing FiBAR®, the process is very similar to that of steel rebar. The super-lightweight material makes it easy for laborers to work on-site, improving their efficiency.

To install FiBAR®, place it in the required position, ensuring it is correctly aligned and supported. Note that FiBAR® is a straight bar that cannot be bent post-curing, so it's important to use the appropriate lengths and sizes for your project.

Once the FiBAR® is in place, it is possible to tie the rebars using plastic clips or plastic fix clips which can be quicker and easier than traditional tie wires. 

Overall, the installation of FiBAR® is a simple and straightforward process that can be done in the same way as for steel rebar.

7. How to unwind FiBAR®?

Unwinding a coil of FiBAR® is a super simple process. To unwind the FiBAR® coil, you can simply place it on a suitable unwinding stand or a clean flat surface and start unrolling it. 

When unwinding FiBAR®, it is important to take care to avoid any damage to the product. Be sure to handle the coil with care and use appropriate equipment to support and stabilize it as you unroll it.

The unwinding of a GFRP rebar, FiBAR® coil is a quick and easy process that can be done using a variety of different methods. Watch how we unwind a coil of FiBAR® here:

8. How to bind FiBAR®?

When it comes to binding FiBAR®, there are a few different options available depending on your needs and preferences.

1. Plastic fix-clips can be used to bind GFRP rebar FiBAR®. These clips are designed to snap onto the rebar while tieing it around the rebars together.

2. Plastic clips provide a secure and reliable method of tying the bars together, and they can be quicker and easier to use than traditional wire ties.

3. Knitting wire can also be used to tie FiBAR® together. Knitting wire is made from high-quality steel wire specially designed to work with reinforcement bars, providing a strong and reliable bond.

Overall, there are several different methods for binding FiBAR®, including plastic clips, knitting wire, and plastic fix-clips. By choosing the right method for your project and following the appropriate procedures, you can ensure that your FiBAR® installation is strong, reliable, and long-lasting.
