Composite glass fiber reinforcement is one of the most popular and modern building materials all over the world (also known as FRP, GFRP, or Fiberglass Rebar).
So why composite rebar is the construction material of the future?
ADVANTAGES: 1) Resistance to the breaking of composite reinforcement is twice as higher as that of A-III class steel reinforcement with the same diameter. Correspondingly, its calculated surface can be twice as smaller as that of steel reinforcement.2) Resistance to corrosion It does not destroy concrete. Steady for corrosion and aggressive environments.3) Thermal conductivity of composite reinforcement is 100 times lower than that of steel reinforcement and, practically, it does not conduct heat. Therefore, it cannot become a thermal bridge and it reduces heat losses considerably.4) Durable and ecological Composite reinforcement extends the period of use of a structure 2-3 times more as compared to steel reinforcement, especially under the influence of aggressive environments. The forecast period of use – min. 80 years.5) High safety and functionality No electric or electromagnetic conductivity, no magnetism, and no disruption of sensitive electronic installations. It is transparent to radar and radio waves.6) LightweightThe weight of the GFRP rebar is 10 times less in comparison with the weight of the steel rebar. So it reduces transportation costs.7) High strength in a wide range of temperatures It is resistant to a wide range of temperature operating conditions: From -70 С to +1008) Savings up to 50% Taking into account the equal-strength replacement of rebar, fiberglass rebar replaces steel rebar with a smaller diameter, savings are up to 50%.9) Savings of up to 90% on transportation Due to its lightweight, the transportation of fiberglass rebar is much cheaper. One truck can fit up to 400 km of rebar.10) The flexibility of sizes – rods of the desired lengthThe length of the composite rebar in coils can be 50-200m but can be easily cut off to the desired length.

We continue to use innovative methods to produce composite products and remain cost competitive with steel and GFRP rebar counterparts
When comparing the costs of fiberglass rebar vs. steel rebar it can be easily stated the difference in the initial cost. However, there are many reasons why fiberglass rebar ends up becoming a more affordable competitor to steel rebar.
● Steel rebar has susceptibility to corrosion or oxidation when exposed to salts, aggressive chemicals, and moisture. As it corrodes, steel rebar swells and increases the tensile load on the concrete, which begins to crack and spall, creating openings that lead to further and faster deterioration of the steel and concrete. This causes costly repair and maintenance and, if allowed to progress far enough, it can compromise the structure’s integrity.
● Fiberglass rebar can also lower costs by cutting down on the use of labor, decrease installation charges, reduce the need for maintenance, and has a longer lifespan than many medals.
● Fiberglass rebar has 2x the tensile strength, 1/4 the weight of steel and 45 GPa and 60 Gpa modulus of elasticity.
