FAQ - Composite-Tech Equipment and GFRP Technology

GFRP Technology & Steel Comparison

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.

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.

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.

We offer fibers with diameters from 0.5 mm to 2.0 mm — an industry-first range. Length can be tailored from 5 mm to 100 mm, depending on the application. Custom cutting systems allow on-demand production.

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.

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.

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.

Yes. Our GFRP fiber has been tested in certified European laboratories. Key results:
• Flexural toughness index improvement: +40–70%

• 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

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.

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

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.

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.

Yes. It is particularly effective in thin floor toppings, screeds, or heated flooring systems, enhancing tensile strength and preventing microcracking.

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.

Yes. Mesh rolls unroll smoothly and can be integrated with semi-automatic or fully automated plastering systems.

Use Cases & Industries

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.
