Australia's Most Comprehensive Glass Fibre-Reinforced Polymer (GFRP) Bar Guide
Madewell Products is an Australian-owned supplier of premium, innovative products for the concrete construction industry. Our brands have been specially curated for their innovation at every stage of concrete construction. We specialise in GFRP (glass fiber reinforced polymer)Talk to a GFRP expert
The Need For GFRP Bars
Corrosion of steel reinforcement
Most concrete bridge infrastructure starts to deteriorate only after 30 years of service (Austroads, 2016).
GFRP bars eliminate corrosion which eventually causes failures in structures, representing a clear public health & safety hazard
Smaller carbon footprint than steel bars
Increased durability = longer design life of concrete structures
Expected life span of GFRP Rebar is more than 100 Years.
The use of GFRP bars in infrastructure can contribute to longer service life of public infrastructure
Repair or replacement costs associated with steel corrosion in Australia are estimated at AU$8 billion per year.

Why Choose GFRP over Steel Reinforcement?
GFRP Rebar is an excellent replacement for conventional types of steel rebar.
✔ Lightweight reinforcement
¼ the weight of steel – less labour, less freight, faster & safer on-site handling
✔ Corrosion free reinforcement
perfect for highly corrosive environments (exposed to water, salt & humidity)
✔ Higher Bond Strength
increasing the rebar spacing
✔ High tensile strength
2x times greater than steel
✔ Cuttable reinforcement
TBM tunnel development and soft-eyes
✔ Non-conductive reinforcement
perfect solution for high voltage currents and magnetic fields.
✔ Non-magnetic reinforcement
hospital & laboratory applications
✔ Risk free alternative to epoxy coated steel, galvanised rebar and stainless steel – (no accelerated corrosion or anodal corrosion due to scratches during on-site handling)
low carbon footprint

GFRP Design Codes
Since the mechanical properties of GFRP fiberglass rebar differ from those of steel, design engineers should consider the requirements and recommendations stated in published design and construction guides when using GFRP fiberglass rebar in structural applications.

Fibre-Reinforced Polymer Bars (DR AS 5204 2023)
This document sets out the criteria for the acceptable materials for the production, the minimum physical, mechanical, and durability properties of glass and basalt fibre reinforced polymer (FRP) bars used for internal and non-prestressed reinforcing concrete in the form of straight or bent bars.
GFRP Handling & Safety Instructions
GFRP composite rebars are highly durable, making them easy to handle and install. Incorrect handling could compromise safety and performance. Please observe the following guidelines for handling, safety and storage.
