GFRP Concrete Reinforcement
GFRP Concrete Reinforcement
The use of GFRP reinforcements as an alternative to steel eliminates the risk of corrosion and the related maintenance costs. GFRP provides an efficient solution for internal structural reinforcement, offering several advantages: it weighs only one-quarter of steel, is easier and safer to handle, and requires no maintenance or corrosion protection.
Life-cycle cost analyses show that GFRP reinforcement combines competitive pricing with zero maintenance, outstanding durability, and an extended service life. With its high tensile strength, elevated modulus, and superior physical and mechanical properties, GFRP represents a sustainable and high-performance choice for modern structural design.
ADVANTAGES
Long Life Cycles
Corrosion-Free
High Tensile Strength
High Chemical Resistance
Thermal Insulation
Easy To Cut
Easy to Handle and Install
Low Environmental Impact
Highly Durable
iBAR
The reinforcement bar consists of a multitude of continuous EC-R type glass fibres, oriented in the direction of load, bonded by a polyester or vinylester matrix. The production ensures the complete impregnation of the fibers, guaranteeing high longitudinal strength and rigidity. The matrix keeps the fibers in place, distributes loads, and protects them from damaging agents. The ribs on the surface increase tensile strength and ensure optimal adhesion to concrete, comparable to that of steel reinforcing bars.
iBAR BENDED
Bent bars and stirrups are made by bending a bundle of resin-impregnated fibers. Subsequently, these raw bars are heat-cured. This procedure allows a high fiber content and near-parallel alignment, thus providing high strength and a modulus of elasticity similar to that of straight bars. Bent bars can be produced in 2D (e.g. z-shaped, circular or rectangular) and in 3D (spirals).
iBAR HP BS
To increase eco-compatibility, basalt fibre rebars (BFRP) can be used. Derived from natural volcanic rock, they are considered non-polluting, as their production requires fewer chemical additives than many synthetic fibres. Basalt fibres offer mechanical properties comparable to GFRP, including good tensile strength and high resistance to corrosion and elevated temperatures. Their use supports the development of more sustainable, durable, and resource-efficient structures.

iMESH 1 P
The monolithic GFRP mesh is designed to offer high stability and durability. It is made of fibreglass rebars without ties, joined together by a structural weave that creates a single, resistant body.
The rebars, consisting of continuous glass fibres impregnated with thermosetting resin, guarantee uniform performance and excellent adhesion to cementitious materials. The transverse arrangement of the rebars is achieved through an automated system that ensures geometric precision and regular mesh spacing.
During production, preforming defines the final geometry and fibre alignment, while a heated mould completes the polymerisation, giving the mesh its final shape. The result is a compact, stable structure that is ideal for permanent applications.
ADVANTAGES
Structural and non-structural reinforcement
Restoration in environments exposed to corrosion
Industrial flooring
Structural slab and screed
Reinforcement of prefabricated elements
Agricultural structures
Reinforcement of floor slab

Low-carbon-footprint production
GFRP requires energy-efficient processes:
-
No merger
-
No high-temperature oven
-
No fossil fuels are used; steel requires temperatures exceeding 1,500°C, whereas GFRP is produced at temperatures below 200°C. According to EuCIA (European Composites Industry Association), it generates 60–70% less CO2 per tonne.
Lighter transport
GFRP weighs approximately four times less than steel, which results in:
-
Fewer trucks on the road
-
Lower fuel consumption
-
Reduced use of lifting equipment
More sustainable lifecycle
Steel-reinforced concrete lasts 25–40 years; with GFRP, it can last up to 100 years, avoiding two rebuilds and reducing:
-
The production of new cement
-
Demolition waste
-
Transport and landfill disposal: Over its lifecycle, GFRP can reduce CO2 impact by 30–45%.
