GraphenBar®
Non-corrosive glass fiber reinforcement bars (GFRP)
Innovation in structural reinforcement for more sustainable construction
Lightweight, durable, non-conductive reinforcement for reinforced concrete in demanding infrastructures.
GraphenBar® bars are fiber-reinforced polymer (FRP) reinforcements designed to replace traditional steel in concrete applications.
Thanks to their pultrusion manufacturing using high-performance fibers and specialized resins, they offer up to 100 years of service life, eliminating corrosion problems and reducing environmental impact.


Main advantages of GraphenBar
Beyond steel: benefits that extend the lifespan of your projects.
Durability without corrosion in marine environments, chlorides and aggressive agents
Up to 4x lighter than steel
Which facilitates transportation, installation and logistics.
High performance per weight
And excellent long-term stability.
Lower life cycle cost
Zero interference.
Lower life cycle cost
compared to steel in aggressive environments.
Lower environmental impact compared to steel
Product ranges
Two matrices (Epoxy and Vinylester) and diameters 6–20 mm to adjust the GFRP performance to each project.

GraphenBar® FiberGlass Epoxy
Reinforcing bars made of fiberglass (GFRP) and epoxy resin, designed to replace steel in reinforced concrete structures. They combine high mechanical strength, light weight, and dielectric stability, making them ideal for bridges, docks, wastewater treatment plants, structures near sensitive equipment, and projects requiring rapid installation and a long service life.

GraphenBar® FiberGlass Vinyl
Fiberglass reinforced concrete reinforcement (GFRP) with vinyl ester resin is designed to withstand aggressive chemicals and saltwater exposure. Ideal for marine and hydraulic environments, retaining walls, and areas with freeze-thaw cycles, offering long durability and optimized overall cost compared to steel.
- Available diameters: 6, 8, 10, 12, 16, 20 mm.
- Available diameters: 6, 8, 10, 12, 16, 20 mm.
Sectors and uses where GraphenBar® fits best
Road, coastal, hydraulic, and underground infrastructure: maximum durability without corrosion and zero interference.

Road infrastructure
Bridges, viaducts, retaining walls.

Maritime and hydraulic works
Dikes, docks, canals, treatment plants.

Civil and industrial building
Foundations, tanks, elements subjected to electromagnetic fields.

Foundations, tanks, elements subjected to electromagnetic fields
Diaphragm walls, soft-eyes, piles and tunnels.
Why switch from steel to GFRP with GraphenBar®
-
+ Service life,
– maintenance in aggressive environments. - + Productivity on site: less weight, fewer personnel for handling, faster installation.
- + Regulatory Compatibility: Designed to comply with ACI 440 and ASTM D7957 (common references in GFRP specification).

FAQs
Ask us anything!
What is the difference between Epoxy and Vinylester?
Both matrices offer strength and durability; Epoxy is often selected for its structural performance and stability, while Vinylester is chosen when chemical/saline resistance is a priority. (In line with typical FRP market positioning.)
Are they compatible with codes and standards?
The GFRP specification typically references ACI 440 and ASTM D7957 for design and acceptance.
Where do they add more value than steel?
In corrosive environments (marine, chlorides, de-icing) and where it is critical to reduce weight and electrical interference.
