The process of creation

Why choose a composite rebar?

Mateenbar™ is created by a technique called pultrusion. It uses a mixture of glass, carbon and basalt fibres that are pulled through a polymer resin bath and then through another section of the machine for heating and drying.


The last step is to tension the formed bar further as the material dries and sets. The process is fast and efficient and helps to reduce emissions from our planet. Post-tension cables are the best comparison of the pultrusion process within construction to visualize the process.


Post-tension cables are stressed three times after the concrete has been placed & finished to make them tighter each time. Once the desired tension has been reached, they fill the cable with grout that encases the wire, which helps hold the slab up through the pressure and stress of the wire.


GFRP Composites are non-corrosive, lightweight, and will achieve a design life of 100+ years minimum. Mateenbar™ has a unique combination of mechanical properties that can still provide exceptional performance and durability in challenging and corrosive environments.


Mateenbar™ GFRP composites have been used within construction in over 1500 projects worldwide in Australia, the US, Canada, Paris, U.A.E., and New Zealand.


The savings that you gain from using Mateenbar™


  • Longer asset life cycles. Durable rebar requires no maintenance and preventative corrosion measures.

  • Codes have been improved over time. In praise of the high performance of modern GFRP rebars, the amounts required for reinforcement have been reduced.

  • The design and manufacturing of GFRP rebar have been optimised and are competitively priced against steel.

  • They are eradicating the threat of infrastructure corrosion, resulting in reprieves across the entire asset life.

  • Less upkeep (e.g. roadworks) decreases economic losses through delays and company interference.

  • 4x lighter than steel means less tonnage to transport.

Raw Materials

• Composite materials have a 15% lower carbon footprint than steel*


The Manufacturing Process

• Minimal heat, water, and energy used

• Lower CO2 emissions

• Process efficiency = minimal waste



• Four times lighter than steel

• More products per truckload

• Less fuel required for transportation



• Increases asset lifecycle by as much as four times

• Zero maintenance required.

• Less cement content is needed to achieve strength



• GFRP composites can be used as aggregate in concrete to create a circular material for construction works
