COMPARISON OF GFRP VS STEEL

Advantages of using GFRP

LIGHTWEIGHT AND IMPACT RESISTANT

A GFRP bar weighs a quarter of its steel equivalent, resulting in significant savings in material placement, maintenance, storage and transportation. It has 20 times the fatigue strength of steel and greater flexibility. It also has a substantially higher bond strength to concrete and cement than steel, making it more resistant to cracking.

DOES NOT PROPAGATE FIRE AND HEAT

GFRP reacts to a flame as a fire retardant, preventing its propagation. It has a very low smoke development, a very low emission of toxic fumes. It does not generate flammable vapours, has zero thermal conductivity and maintains its properties almost intact at high temperatures. In addition, GRP can be reinforced with fillers or additives that reduce the effects of heat, ultraviolet radiation and fire.

NOT ELECTRICALLY CONDUCTIVE

GFRP does not contain metals in its composition, which means that it does not conduct electricity or interfere with magnetic fields, so it does not affect the operation of electronic devices. This characteristic is very important in structures that work with electricity, such as railway structures, power generation plants, high voltage wiring... All this allows the construction of safe working spaces for all personnel.

MORE ECONOMICAL AND DURABLE

Thanks to its light weight, high strength and durability, considerable savings in storage, transport, installation and maintenance are achieved. In addition, the production of corrugated rods reinforced with fibreglass using the pultrusion technique, which we use at GFRP Rebar Techonology, results in a professional, durable and economical product. Due to its characteristics, it does not require special treatments for its conservation when stored for long periods of time. .

DOES NOT RUST OR DEGRADE DUE TO WEATHERING

Unlike other materials such as steel or wood, glass fibre reinforced polymer offers high resistance to chemical or environmental agents, such as salt water, oils, crude oil derivatives, solvents... Its anti-corrosion properties make it the ideal reinforcement solution for structures in aggressive environments. GFRP prolongs the useful life of any structure or building.

STEEL VS GFRP

Comparison of steel vs glass fibre reinforced polymer. Which is better, GFRP or steel? Is a steel bar harder than a GRP pultruded bar? durability, properties, uses, characteristics, pultrusion

GFRP or glass fibre reinforced polymer has been used for decades in all kinds of industries and structures, from shipbuilding and aerospace to rail infrastructure, tunnels and bridges.

GFRP properties

GFRP or glass fibre reinforced plastic does not rust and is highly resistant to corrosion. Unlike metals such as steel, it is resistant to acidic environments, chemicals and adverse weather conditions. It does not conduct electricity and is highly resistant to impact. A pultruded GFRP bar weighs up to 75% less than its steel equivalent. Both have a similar level of internal stress, with the advantage of the lower weight of the GRP corrugated rods.

What is GFRP? What is GRP? Meaning of glass fibre reinforced polymer. Spain Pultruded profiles do not rust.

The development of polymer or plastic technology has been one of the great revolutions of the last century, which has been perfected to the present day. The latest manufacturing and recycling techniques have resulted in highly resistant, lightweight and durable materials, which are ideal for all types of industrial and construction work.

GFRP stands for Glass Fiber Reinforced Polymer. In Spanish it is called PRFV (Fibreglass Reinforced Plastic or Polymer), although other terms such as FRP, PRF or GRP are also accepted.

PULTRUSION

At GFRP Rebar Technology we use the most advanced system in the manufacture of GFRP bars, rods, tubes and meshes. Called Pultrusion, it´s an automated process for the production of glass fibre reinforced profiles.

What is pultrusion? Pultruded or pultruded profiles. Glass fibre reinforced polymer manufacturing What is pultrusion used for? 

Pultruded profiles

The resulting product is called a pultruded profile or RFV profile, which is the result of a combination of glass fibres with polymeric or epoxy resin. Pultrusion offers remarkable benefits. It offers the possibility to obtain different types of pultruded profiles. It has a high productivity and produces hardly any waste.
