What is GFRP Rebar?

GFRP (Glass Fibre Reinforced Polymer) rebar, commonly referred to as Fibreglass reinforcement, is a high tensile strength alternative to steel reinforcement. GFRP is made by weaving high quality glass fibres into a fabric before being impregnated with polymers and formed into a round bar.

Why use GFRP? What are the benefits?

The key overwhelming benefit of GFRP reinforcing bar is it’s resistance to corrosion. Rust is a major risk to steel reinforcing in concrete structures located in high corrosion environments such as near saltwater or chemicals. Fibreglass reinforcing is highly resistant to corrosion and can extend the lifespan of concrete structures enormously. GFRP reo bar is also incredibly lightweight and strong. Most fibreglass rebar weighs 1/4 the weight of an equivalent size steel bar with two times the tensile strength.

Safari Group sells a broad range of GFRP bars in diameters ranging from 8mm up to 38mm. Most GFRP is stocked in 6m lengths. We supply GFRP rebar to projects all over Australia including Sydney, Melbourne, Brisbane, Perth and mining and rural areas.

Glass Fibre Reinforced Polymer reinforcing bar can be cut on site with an angle grinder or similar tool, but it cannot be bent to shape in the same way steel rebar is. Safari Group can supply GRFP bar prefabricated to order in special shapes such as corner bars and starter bars.

GFRP is also commonly used as a replacement for steel dowel bars in areas of high corrosion. GFRP dowels are ideal for load transfer between concrete slabs. Our FRP dowels can also be supplied with a plastic sleeve and nailing plate for easy install.

• Fibreglass reinforcement is highly resistant to corrosion and rust - greater than 100 year design life

• High tensile strength - 2 x steel

• Commonly used in wharves, bridges, jetties, underwater and other marine structures

• GFRP does not conduct electricity - often specified in concrete slabs for electrical compounds and substations

• Incredibly lightweight - easy to transport and place reinforcement

• Fibreglass rebar can be used to form a GFRP fibreglass mesh mat for boat ramps, wharfs and other marine projects.

For high corrosion environments, we also sell a range of Stainless steel reinforcing bar - click here for details.

NOTE: Standard GFRP bar is not threaded but this can be arranged on request
