Fiberglass Reinforcement Bars with Graphene
Innovation in structural reinforcement for more sustainable construction
Lightweight, durable, and non-conductive reinforcement for reinforced concrete in demanding infrastructures
GraphenBar® rebars are fiberglass-reinforced polymer (FRP) reinforcements designed to replace traditional steel in concrete applications, offering an alternative for light residential and commercial projects.
GraphenBar® withstands all weather conditions, ensuring long-lasting performance with no maintenance required.
Structural safety guaranteed
GraphenBar® does not oxidize or degrade in contact with water, chlorides or aggressive chemical agents
Up to 70% weight reduction compared to steel, making transport and installation easier
Lower cost thanks to its easy handling and lower weight, and reduced maintenance costs
High tensile strength (>1000 MPa) and compression
Non-conducting and thermally stable
The reinforcement that doesn’t interfere with your infrastructure
GraphenBar® requires fewer resources and generates a significantly lower carbon footprint than traditional steel.
Fiberglass and epoxy resin reinforcement bars, designed to replace steel in reinforced concrete structures. They offer high tensile strength, thermal stability, and superior durability, even in aggressive environments. Ideal for civil and industrial infrastructures that require safety and sustainability.

Comparison with Steel and Aluminum
The higher specific strength of composite materials allows greater energy efficiency per component.
Despite their high recycled material content, the energy consumption in ingot and secondary operations results in a disadvantage for aluminum compared to composites in terms of total energy consumption.
*La rejilla de acero es 3,5 veces más pesada que la de composite.
*La rejilla de aluminio es 1,2 veces más pesada que la de composite.
Lightness, resistance and sustainability
Graphenbar® FRP reinforcement bars have only about 27% of the weight of steel reinforcement bars. This allows for lighter structures with maximum stability and reduced dead load, as well as much easier handling on construction sites.
Graphenbar® FRP reinforcement bars have a tensile strength three to four times higher than conventional reinforcement bars made of plain carbon steel or stainless steel. Tested in accordance with CSA S806 / ASTM D7205 standards.

Choose GraphenBar® for projects that demand strength, ease of use, and durability.
GraphenBar® has a tensile strength greater than 1000 MPa (145 ksi). Compared to steel, GraphenBar® can withstand more than three times the tensile load of steel before failure.
GraphenBar® has a tensile modulus greater than 67 GPa (9427 ksi). Compared to steel, GFRP rebar is more flexible, allowing it to absorb seismic energy more effectively due to its improved properties and lower density.
GraphenBar® has a tensile strain between 1.5% and 2.5%.
Graphene fiberglass rebars are available in standard sizes from 6 mm to 20 mm. Other sizes are available upon request.
Tie GRP rebar with stainless steel or nylon wire. You can also use zip ties or fiberglass-reinforced tapes. If corrosion or electromagnetic fields are not a concern, regular wire can also be used.
GraphenBar® costs significantly less than stainless steel. Its price is also lower than that of steel rebar, and when considering all the savings from labor costs, corrosion protection additives, concrete cover, and transportation, the total cost is much lower than that of steel rebar.
GraphenBar® is made of fiberglass, which is 100% recyclable, and epoxy resin with graphene. When embedded in concrete, the material can be crushed together with the concrete after more than 100 years, without needing to be removed, and it can become part of the next recycled concrete—making the new concrete much stronger.
