FRP Rebar VS Steel Rebar

Does FRP rebar can instead of steel bar for construction application, if you want to know, firstly, we need to

Know, what’s the difference of FRP rebar and steel rebar, they have some save features, but also has difference points, let’s learn about it.

Price Difference:

For fixed length, the cost of FRP rebar is lower more than steel reber.

For example, Diameter 12mm FRP rebar,

Steel Rebar : Length 1100Meter, Weight 1ton, Total Cost 630USD

FRP Rebar: Length 5000Meters, Weight 1 ton, Total Cost 1600USD

It equal to same length, cost of steel bar is around 1.8 times of FRP rebar.

Weight Difference:

FRP rebar only 1/4 of the same volume of steel rebar; The density is between 1.5-1.9 (g/cm3).

Tensile Strength:

FRP rebar better than steel rebar.

the tensile strength of steel bars is 300-500MP, the tensile strength of glass fiber bars is 600-800MP, the tensile strength of glass fiber bars is better than that of ordinary steel, 20% higher than that of steel bars of the same specification, and the fatigue resistance is good.

Construction period:

FRP rebar better than steel rebar.

Compared with ordinary steel bars, fiberglass reinforcement is customized by manufacturers. Since it cannot be processed on site, it is necessary to accurately control the size. Once the material is cut incorrectly, the construction period will be delayed. Its shape is directly customized, which reduces the processing steps of ordinary steel bars, and the lap joint method of binding replaces the welding process, which saves the production time of the reinforcement cage.

Electric and thermal insulation, thermal expansion coefficient

Electric and thermal insulation, thermal expansion coefficient is closer to cement than steel bars, etc. It is mostly used in shield tunnels through underground diaphragm walls, column piles, uplift piles, including the entrance and exit of subway station end wells, many of which are made of glass. Fiber tendons.

Advantage of FRP rebar.

FRP rebar has lots of advantage when use at construction field, such as anti-corrosion, high tensile strength, light weight, Antistatic, non-conductive etc.

–Light weight

Only 1/4 of the weight of the steel bar of the same specification.

-High strength

Tensile strength is about twice or three times of the load of the steel bar of the same specification.

-Lower labor cost

The labor intensity of workers is greatly reduced.

-Lower transport cost

Because of lower weight, easy to transport, save transport cost for project.

–Corrosion-resistant

Corrosion-resistant bolt base materials are durable materials, and through the composite process molding. Service life is up to 100 years. It can be used as permanent support material.

–Antistatic, non-conductive

Antistatic, non-conductive, no spark when cutting, especially suitable for high gas area.

-Other advantage

The whole length of FRP bolt body is provided with equidistant thread, that is, “full thread”; Flame retardant, high heat insulation, insulation, no magnetic field.
