What is FRP Rebar?
COMPARISON OF FRP AND STEEL REBAR
FRP, or fiber reinforced polymer, is a composite material made of reinforcing fibers and matrix resin.
It is designed to address the problem of steel corrosion, which weakens traditional reinforced concrete structures.
FRP can be used in a variety of applications due to its ability to be customized with different types of matrix resins such as unsaturated polyester, epoxy, vinyl ester and polyurethane. These resins have different properties that enable FRP to meet a wide range of requirements.
Additionally, different types of reinforcing fibers can be used in FRP, including glass fibers, basalt fibers, and carbon fibers. Each type of fiber has its own unique properties, such as high strength, corrosion resistance, and durability, making FRP a versatile and effective material for building and structural applications.

WHY CHOOSE FRP REBAR
Quality, performance and cost are all key factors that must be considered. A balance must be struck between these variables when making decisions. Unfortunately, people tend to prioritize immediate benefits over the long-term benefits that can be achieved.
If we choose to take shortcuts today and ignore the need for proper planning, we will end up spending more money in the future repeatedly demolishing and rebuilding.
Although the upfront cost of FRP rebar is typically higher, the long-term cost benefits of its durability and reduced maintenance outweigh the initial investment.
Now is the time for responsible planning, including a careful examination of service life forecasts that are critical to long-term value engineering. Building our nation's infrastructure and building our homes requires the use of high-quality, efficient materials.
Regarding the carbon footprint, it is worth noting that steel production has a much greater environmental impact than FRP rebar production. This is true even without taking into account the additional carbon footprint created by repeated demolition and restoration.
Adopting a more forward-thinking approach and considering the potential benefits that may arise in the future.
By doing so, we can ensure that our actions lead to sustainable and lasting results.
PROVEN RELIABILITY
By meeting the stringent standards set by ACIASTM, BS, CSA, ISIS and JECE, GRECHO ensures that its FRP rebars not only have superior strength and durability but also meet the specific requirements of various industries and regions.
Whether it is construction, infrastructure or any other application, customers can be confident in choosing GRECHO's FRP rebars because it meets the highest performance and safety standards.
GRECHO GFRP REBAR
GFRP rebar is an innovative building material that combines fiberglass reinforcement with resin.
It is widely considered to be the best performing composite rebar due to its excellent strength to weight ratio, corrosion resistance, ease of cutting and non-magnetic properties.
This versatile fiberglass rebar can be effectively used in a variety of applications, including traffic pavement reinforcement, subway tunnel shields, underground foundations, coastal development and photovoltaic support systems.
GRECHO BFRP REBAR
BFRP rebar, or basalt fiber reinforced polymer rebar, is made using basalt fiber as reinforcement.
Basalt fiber is derived from natural volcanic basalt and has the advantages of environmental protection, high and low temperature resistance, heat and sound insulation, and reinforced properties similar to glass fiber reinforced polymer (GFRP).
BFRP is characterized by its ability to resist rust, act as an electrical insulator, and be non-magnetic. It has excellent acid and alkali resistance, helping to improve the durability of construction projects.
Applications：
1. Dam, dock, reinforcement construction, mining roadway support.
2. Concrete road bridge reinforcement, NMR/CT house(Hospital), Corrosion-resistance construction.
3. Cable core reinforcement, optical cable, transformer substation, TV telecom transmission tower, etc.
GRECHO CFRP REBAR
CFRP rebar, the abbreviation of carbon fiber reinforced polymer rebar, is a cutting-edge fiberglass rebar that uses carbon fiber as a reinforcing material and is produced through a pultrusion process using epoxy or vinyl as the base material.
CFRP rebars have superior tensile strength and lightweight composition compared to other FRP rebars. This combination significantly reduces the overall weight of the building project while still meeting necessary design performance requirements.
Applications:
1. New bridges as well as the repair and renovation of existing bridges.
2. Reinforcement of marine structures such as piers, docks and seawalls.
3. High-rise buildings, parking lots, and industrial facilities.
4. Columns, beams, slabs and retaining walls.
5. Reinforcing buildings and infrastructure in seismic zones.
6. Restoration and restoration of historic buildings.
FREOUENTLY ASKED OUESTIONS
One of the leading causes of decline in our infrastructure is corrosion of concrete steel reinforcement. Not only does this shorten the life of the concrete, it also results in higher repair costs and poses safety risks. However, with fiberglass rebar, you can eliminate the rust problem entirely.
GRECHO fiberglass rebar is made entirely of non-metallic materials, providing a durable solution that competes with steel on price. In addition, it is electromagnetically inert, making it particularly suitable for sensitive areas.
GRECHO Fiberglass rebar is much cheaper than alternatives like stainless steel, MMFX, and other rebar options. Prices may vary slightly depending on market conditions and raw material factors. Please feel free to contact us for a new quote.
Absolutely! GRECHO fiberglass rebar successfully replaces steel rebar in many structures, regardless of size or shape. However, it's worth noting that it may not always be a direct replacement. Depending on the specific requirements of your project, you may need slightly more or less fiberglass rebar. Our designs are often influenced by factors such as serviceability and crack width.
GRECHO fiberglass rebar weighs only one-quarter of steel rebar, which is a significant advantage. This reduced weight provides several benefits during placement. First, it increases productivity and, depending on the complexity of the project, may reduce installation time by more than 50%. Secondly, lighter loads minimize the risk of injury and fatigue associated with handling heavy materials and create less danger if they are accidentally dropped. In addition, the reduction in weight can save on shipping costs because greater quantities of material can be transported. Additionally, the lighter weight of steel bars helps achieve lighter concrete structures, which can be advantageous in certain applications.
Binding Material: To secure GRECHO fiberglass rebar, you can use plastic-coated tie wire, which is the most common method and is similar to steel rebar. Where metal is not allowed, nylon cable ties can be used as an alternative.
Lap Joint: Lap joints for GRECHO fiberglass rebar follow the same procedures as steel bars and can even be tied to the steel. The required length may vary, so the correct value must be confirmed before placing the bars.
Deal With: Although GRECHO fiberglass rebar is a durable material, like any other material, it should still be handled with care. Avoid dragging or physically damaging the reinforcement during handling.
Cutting: GRECHO fiberglass rebar is very easy to cut and can be cut using a variety of saws. We recommend using a circular saw with a diamond blade for best results. However, a reciprocating saw equipped with a blade designed for cutting metal can be used on individual bars. Do NOT attempt to shear or torch the bar, as this will damage it and render it unusable.
All bends must be made in the factory and field bending is NOT allowed. We can offer customization to ensure you get exactly what you need!
