Frequently Asked Questions on GFRP

What is glass fiber reinforced polymer?

It is a material composed of fibreglass and resin. The union of these two compounds results in a durable and very resistant product. It comes in various formats such as bars, rods, meshes or tubes. Reinforced plastic is lightweight, durable, strong and resistant. and does not conduct heat or electricity, which is why it is used in all types of industry.

What is GFRP?

GFRP stands for Glass Fiber Reinforced Polymer, (polímero reforzado con fibra de vidrio in Spanish). The terminology used to refer to polymer or plastic corrugated rods that have been reinforced with glass fibre. It represents an efficient and durable alternative to steel bars. Its most notable properties are non-corrosion, tensile strength and low weight.

What is GFRP Rebar Technology?

We are authorized manufacturer and distributor of GRP structural reinforcements. We have a wide catalogue of reinforced polymer products such as bars, rods, tubes and reinforcement meshes.

What does PRFV mean?

This stands for Glass Fibre Reinforced Polymer or Fibreglass Reinforced Polymer. It is the terminology used to refer to products derived from GFRP, also known as FRP and GRP.

Why use GFRP instead of steel for reinforced concrete reinforcement?

GFRP has superior properties to steel in a number of respects. Firstly GRP never rusts. In addition, GFRP or GRP structures have far superior tensile properties, much better corrosion resistance and inherent electromagnetic neutrality. On the other hand, the rods or GRP reinforcing bars are a more economical, durable and sustainable solution.. As it has no metals in its composition it does not conduct electricity, making it an ideal choice for constructions or structures working with medium and high voltage lines.

Is GFRP flammable?

With respect to fire, GRP does not promote dispersion and is a good thermal insulator., compared to steel (the most commonly used metal for construction). It has good resistance to burning, which provides an effective barrier against heat, toxic gases and smoke. In addition, it can be covered with materials that provide extra protection, the most effective against fire being rock wool, cork agglomerate and calcium silicate.

What are the main properties of GFRP?

Materials derived from glass fibre reinforced polymer production have a low weight and are extremely strong and resistant.. It is a non-slip material (suitable for railings, cracks, gratings, sewers or drains), resistant to corrosion and does not propagate heat, electricity or fire. Structures made of GFP have a low production and installation cost and are very durable, compared to other minerals and metals such as iron or steel.

Can GFRP be welded?

In contrast to steel, GFRP cannot be welded, but efficient alternatives do exist. There is currently a lot of ongoing research on the bonding of composite materials by GFRP. GRP materials can be resin-bonded, riveted or bolted together.

Is it possible to cut GFRP?

Sections or cuts can be made in bars, rods, mesh or any material made of glass fibre reinforced polymer. Low speeds are recommended for optimum results and clean cuts.

What can be built with GFRP?

All types of structures can be realised, from buildings, bridges, railway structures, dams, water channelling... The application of GFRP reinforcements covers all types of sectors, such as industrial, sanitary, agricultural...

How long can a GFRP construction last?

Products made of glass fibre reinforced polymer have a high durability and can withstand many years without compromising their structure. Polymers age very slowly, In addition, external influences such as humidity, heat or UV rays hardly deteriorate their properties and they are extremely resistant in aggressive environments.

What is pultrusion?

Pultrusion is aproduction process based on the corrugation of polymeric materials or plastic materials. The result is reinforced plastic profiles, known as pultruded or pultruded profiles. In addition, thermoplastic pultrusion allows the profiles to be reinforced with other polymer resins, improving their flame-retardant properties or their strength.
