What is FRP?

FRP stands for Fibreglass Reinforced Polymer (also called fibreglass reinforced plastic). It’s a composite material made by combining glass fibres with a resin, creating a lightweight, high-strength material that resists corrosion and chemicals and won’t conduct electricity — making it a durable alternative to steel in harsh environments.

How Is FRP Made?

The glass fibres give FRP its strength, significantly increasing the material’s flexural and tensile strength compared to the resin alone. The resin binds the fibres together and protects them from moisture, chemicals and UV exposure.

There are several resin types used in FRP manufacturing, each suited to different applications and environments — read more in our guide: Which Resin System for FRP Products?

Benefits of FRP

FRP brings a number of benefits over traditional materials like steel and timber:

Excellent chemical and corrosion resistance
Non-conductive to electricity
Lightweight, yet high strength
Impact resistant
UV stable, with fire resistant options available
Low maintenance and reduced lifecycle costs
Easy to fabricate and install

Where Is FRP Used?

FRP is used across a wide range of industries, including:

MaxiGRATE is also available in a range of non-slip finishes to suit a wide range of applications.

Frequently Asked Questions

Is FRP the same as fibreglass?

Not exactly. Fibreglass refers to the glass fibres themselves, while FRP (fibreglass reinforced polymer) is the finished composite material made when those fibres are combined with a resin. The terms are often used interchangeably in industry, but FRP specifically refers to the finished product.

Is FRP fire resistant?

Standard FRP is combustible, but fire-retardant resin systems are available that meet common fire-rating standards. We can advise on the right resin system for fire-rated applications.

How long does FRP last?

FRP has a long service life because it doesn’t rust, rot or corrode. In harsh or chemical environments, it commonly outlasts steel and timber by decades, with minimal maintenance required.

Is FRP stronger than steel?

FRP has a higher strength-to-weight ratio than steel, so it can match or exceed steel’s strength while weighing significantly less. Steel typically has higher raw stiffness, so the right material depends on the specific engineering application.

Does FRP conduct electricity?

No. FRP is non-conductive, making it a safer alternative to steel around live electrical equipment and in environments where conductivity is a hazard.
