The construction industry demands materials that meet ever-increasing performance standards. For a long time, steel fiber was the go-to option for reinforcing concrete, but innovative composite materials, such as GFRP fiber (Glass Fiber Reinforced Polymer), offer far superior performance. In this article, we’ll discuss the advantages of GFRP fiber over traditional steel fiber and introduce the state-of-the-art equipment developed by Composite-Tech for producing GFRP fiber.
What is GFRP Fiber?
GFRP fiber is a composite material made from glass fibers embedded in polymer resins. These fibers are mixed into concrete to enhance its strength, crack resistance, and durability. The use of GFRP fiber in construction is rapidly gaining popularity due to its exceptional mechanical properties and long-term performance compared to traditional materials like steel.
Advantages of GFRP Fiber Over Steel Fiber
- Higher Tensile Strength
GFRP fiber boasts a tensile strength of 1000–1600 MPa, which is more than twice that of typical steel fiber, which ranges between 400–600 MPa. This makes composite fiber far more effective at reinforcing concrete, especially in high-stress applications where extreme loads are present. - Corrosion Resistance
Steel fiber is highly susceptible to corrosion, particularly in humid or chemically aggressive environments, which compromises its longevity and strength. In contrast, GFRP fiber is fully corrosion-resistant, making it ideal for marine, industrial, and chemically aggressive environments where steel would degrade over time. - Lightweight and Easy to Handle
GFRP fiber is 4–5 times lighter than steel with equivalent performance characteristics. This reduces the overall weight of concrete structures and simplifies transportation and installation. The use of composite fiber can significantly reduce logistics and labor costs. - Chemical Resistance
GFRP fiber is resistant to acids, alkalis, and salts, which ensures that it remains stable in chemically aggressive environments. Steel fiber, on the other hand, is vulnerable to chemical attack, which shortens the lifespan of the reinforced concrete structures. - Extended Lifespan of Structures
Thanks to its superior durability, GFRP fiber can extend the lifespan of reinforced concrete structures by 2 to 3 times compared to steel fiber. This makes it an economically efficient choice for long-term projects such as bridges, tunnels, and large infrastructure. - Electromagnetic Inertness
GFRP fiber does not conduct electricity, making it ideal for use in electromagnetic-sensitive environments such as power stations, subway systems, and telecommunications infrastructure. Unlike steel fiber, which can cause electromagnetic interference, composite fiber poses no risk to sensitive equipment.
GFRP vs. Steel Fiber: Comparison Chart

| Chemical Resistance | High | Low |
| Electrical Conductivity | Non-conductive | Conductive |
| Structural Longevity | 2–3 times higher | Reduced in corrosive environments |
| Maintenance Costs | Lower (no need for frequent replacement) | Higher (due to corrosion) |
