FAQ - Composite-Tech Equipment and GFRP Technology
GFRP Technology & Steel Comparison
What is GFRP rebar and how is it made??
GFRP (Glass Fiber Reinforced Polymer) rebar is a non-metallic, corrosion-resistant reinforcing material made by pultruding glass fibers through a thermosetting resin. It is widely used in infrastructure, marine, and chemical environments.
How does GFRP rebar compare to traditional steel reinforcement?
GFRP is 4x lighter, 2x stronger in tensile strength, non-corrosive, and non-magnetic. Unlike steel, it does not rust, making it ideal for long-lasting structures.

GFRP Fiber for Concrete
What is GFRP fiber and how is it different from steel fiber?
GFRP (Glass Fiber Reinforced Polymer) fiber is a high-performance, non-corrosive material used to reinforce concrete. Unlike steel fiber, GFRP fiber does not rust, is lighter, and has excellent tensile strength. It’s made of glass roving impregnated with resin and cut to precise lengths from 5 mm to over 50 mm.

Can GFRP fiber fully replace steel fiber in concrete applications?
Yes. GFRP fiber can replace steel fiber in many applications, including industrial floors, precast elements, pavements, shotcrete, and slabs. It improves crack control, tensile performance, and durability while reducing weight and corrosion risks.
GFRP fiber has tensile strength up to 1,500 MPa, while steel fiber typically ranges 900–1,200 MPa.
What diameters and lengths are available for your GFRP fiber?
What is the recommended dosage of GFRP fiber per cubic meter of concrete?
The dosage varies by application:
• Light structural concrete: 1–2 kg/m³
• Industrial floors: 2–4 kg/m³
• Shotcrete or tunnel linings: up to 5 kg/m³
GFRP fiber has 3–4x lower density than steel fiber, so by weight you use less, and it distributes more evenly.
Is GFRP fiber compatible with standard concrete mixers?
Yes. Our fiber can be added directly into drum mixers, planetary mixers, or ready-mix trucks without the need for special equipment. No clumping, even at higher doses.
How does GFRP fiber improve crack resistance in concrete?
GFRP fiber forms a 3D reinforcement network inside concrete. It arrests microcracks at an early stage, redistributes stress, and improves post-crack toughness. It is especially effective in reducing shrinkage and thermal cracking.
Tested according to ASTM C1609 and EN 14651 for flexural performance.
Has the performance of GFRP fiber been tested and certified?
Yes. Our GFRP fiber has been tested in certified European laboratories. Key results:
• Flexural toughness index improvement: +40–70%
• Shrinkage crack reduction: up to 80%
• Improved concrete tensile strength: +20–30%
In which applications is GFRP fiber most effective?
• Industrial floors and slabs-on-grade
• Precast panels and elements
• Shotcrete and sprayed concrete
• Marine and water-exposed structures
• Tunnel linings and infrastructure projects
• Lightweight structures and facades
How does GFRP fiber affect concrete workability?
Our fiber is engineered for optimal dispersion and low impact on slump. Compared to steel or synthetic fibers, it maintains better flowability, especially in self-compacting concrete (SCC) and pumped mixes.
Can GFRP fiber be used in combination with rebar or mesh?
Yes. GFRP fiber can be used as secondary reinforcement alongside GFRP rebar or mesh to enhance crack control and improve ductility. Ideal for precast and structural elements where multi-directional reinforcement is needed.
Fiberglass Mesh Applications
What is fiberglass mesh used for in construction?
Fiberglass mesh is primarily used for reinforcing floors and road bases, as well as plaster, EIFS systems, and facade coatings. It improves tensile strength, crack resistance, and structural durability in concrete and cement-based layers.

Can fiberglass mesh be used for roads and industrial floors?
Yes. It is increasingly used in road overlays, industrial slabs, and subbase reinforcement to control shrinkage and thermal cracking. GFRP mesh offers high strength-to-weight ratio and corrosion resistance, making it ideal for demanding environments.
Tested under heavy load simulations: crack width reduction up to 70% in floor applications.
What mesh diameters do you offer?
• Standard fiberglass mesh: from 2 mm to 6 mm diameter, suitable for floors, slabs, and road bases.
• Structural mesh (GFRP bars): from 6 mm to 16 mm, made using heavy-duty machinery for structural applications.
Do you manufacture equipment for heavy structural mesh production?
What are the available mesh opening sizes?
We provide meshes with cell dimensions of:
• 50×50 mm
• 100×100 mm
• 150×150 mm
• 200×200 mm
Custom sizes are available upon request, depending on your project needs.
Is fiberglass mesh suitable for facade systems?
Yes. Our mesh is used in EIFS and ETICS facade systems for insulation layer reinforcement. It provides crack bridging and weather resistance in both base and finish coats.
What is alkali-resistant fiberglass mesh?
Alkali-resistant (AR) fiberglass mesh resists degradation from the high pH of cement. It is coated with acrylic or PVC binder to ensure long-term durability when embedded in concrete or plaster.
Can fiberglass mesh be used in self-leveling floors?
Yes. It is particularly effective in thin floor toppings, screeds, or heated flooring systems, enhancing tensile strength and preventing microcracking.
How does fiberglass mesh compare to metal mesh in concrete?
Fiberglass mesh is lighter, rust-proof, easier to cut and install, and does not corrode over time. It is also more elastic, which helps distribute stresses more evenly.
Is your mesh suitable for machine plastering or automated installation?
Yes. Mesh rolls unroll smoothly and can be integrated with semi-automatic or fully automated plastering systems.
Use Cases & Industries
Is GFRP rebar suitable for road construction?
Yes. GFRP rebar is ideal for roads, highways, airport runways, and concrete overlays. It eliminates corrosion problems caused by road salt, water ingress, and freeze-thaw cycles — significantly extending pavement lifespan.
Studies show up to 2x longer service life of concrete pavements reinforced with GFRP vs steel.

• Lightweight prefab housing
GFRP’s low weight makes it perfect for crane-lifted elements and reduces transport costs.
Can GFRP be used in 3D concrete printing?
Yes. Short GFRP rods or fibers can be embedded into 3D-printed concrete layers to increase tensile strength and crack resistance without affecting printability.
Composite-Tech is developing integration modules for GFRP-based reinforcement in concrete printing systems.
Is GFRP used in dam or hydro project construction?
Yes. In spillways, sluice gates, and hydro channels, GFRP provides non-corrosive reinforcement where moisture and chemical exposure are extreme.
Is GFRP suitable for nuclear or electromagnetic-sensitive projects?
Yes. GFRP is non-conductive and non-magnetic, making it suitable for use in:
• Nuclear plants
• MRI rooms
• Electrical substations
• Data centers
GFRP eliminates induced currents and magnetic field distortions caused by steel.
Are there case studies of GFRP in large-scale infrastructure?
Yes. Projects worldwide:
• Dubai Metro (UAE)
• Champlain Bridge (Canada)
• Lusail Stadium precast panels (Qatar)
• Port installations in Norway
How does GFRP perform under freezing conditions?
Unlike steel, GFRP does not expand or degrade under freeze–thaw cycles. It retains mechanical properties in extreme cold (tested to -40°C)
