Composite GRP reinforcement bars

Composite rebars is a construction material that has slowly been gaining traction through its use in infrastructure projects including reservoirs, floors even, highway bridges in the past few years.

Concrete is brittle and has a low tensile strength and it needs additional reinforcing, commonly steel reinforcement bars, or rebar, are used. However, composite rebar has a number of advantages over steel rebar including durability, cost and maintenance over time. Steel rebars corrode and swell over time resulting in cracking or spalling of the concrete structures.

Advantages of Composite rebars 

It is 5 times lighter than construction steel.
Thanks to its low density, although it shares the same dimensions as construction steel, it has a structure that is approximately 5 times lighter. Therefore, composite reinforcement significantly saves on heavy equipment for transportation and handling costs.

Its Tensile Strength Is 2.5 Times More Than Construction Steel.
According to the tensile test results, it has been observed that it has 2.5 times more strength than construction steel. This makes the structures more durable.


Has Low Labor Cost.
Thanks to the lightness of the material and ease of processing, it has been observed that the labor cost has decreased significantly.


It is not toxic.
It is not toxic, it is in the 4th hazard class according to the degree of its effect on the human organism and the environment. (less dangerous)


It Has More Than 100 Years of Use.
It has a service life of more than 100 years, as it does not corrode due to its mechanical and chemical properties and is resistant to chemicals.


It Has Very Low Thermal Conductivity.
Thanks to its low thermal conductivity, it provides energy savings in related structures.

It Has High Corrosion Resistance.
They can be used as structural elements where high corrosion resistance is required. Example usage areas; parking lots, port structures, bridge decks and bridge piers.


It Has High Chemical Resistance.
They can be used as structural elements where high chemical resistance is required. Example usage areas; industrial floors, industrial containers, wastewater treatment, agricultural facilities.


Has Electrical Insulation.
They can be used as a building element in places where electrical insulation is required. Example usage areas; transformers, reactors / inductors, ballastless rail plates (signals and switches of railways), areas with high magnetic fields.


It is not magnetic.
They can be used as structural elements in places with magnetic sensitivity. Example usage areas; precision electronics provider, structural biology, quantum physics, MRI, ballastless rail flooring.
