RPM GFRP (Glass Fiber Reinforced Polymer) Rebar

When thinking of durabilIty, think GFRP!

Glass Fiber Reinforced Polymer (GFRP) is composed of a protective polymer reinforced with high-strength fiberglass. GFRP outperforms steel for bridges, pedestrian pathways and other structures, while holding up to decades of wear and tear. Our manufacturer MST is the world’s largest supplier of high modulus Grade 3 GFRP (other grades available).

RPM GFRP vs Steel:

Discover the key differences between fiberglass rebar and steel rebar that make RPM GFRP the obvious choice.

100 years ago, steel rebar was developed as the only option for reinforcing concrete. However, many of the structures developed before steel rebar are still standing today. Structures using steel rebar in corrosive environments will begin to fail after 10 years.

Corrosion costs the private and public sectors $hundreds of billions of dollars in repair and maintenance costs a year. Corroding steel rebar is a ticking time bomb because determining the moment of failure can mean the difference between life and death.

RPM GFRP can save the current costs of corrosion and eliminate all failures due to corrosion because it will outlive the concrete it is reinforcing.

Greener than Green:

From transport to handling to the manufacturing process – RPM GFRP has numerous benefits for the environment. By using Glass Fiber Reinforced Polymer (GFRP) you:

  • Save CO2 from less transportation
  • Save CO2 from demolition and rebuilding
  •  Save energy by providing better insulation
  • Save the concrete
  • Save the rebar from corrosion
  • Add six LEED credits in Canada

1/4 The weight of steel

Get 4x the amount of product on your trucks and save exponentially on transportation costs.

2.5 to 3x stronger than steel

With a tensile strength 2.5 to 3x the amount of steel and a fatigue resistance 20x the amount of steel.

Greener solutions

The manufacturing process of RPM GFRP produces far less carbon emissions than the steel industry which has a devastating impact on the environment.

Lifespan of +100 years

RPM GFRP will never corrode leading to spalls in the concrete. While steel has a lifespan of 50 years RPM GFRP will outlast the concrete it is reinforcing

Non-corrosive + Non-conductive

RPM GFRP is non-corrosive and suited to any environmental exposure. RPM GFRP does not conduct heat, cold, or electricity.

Superior Bond Strength

Our rebar delivers a bond strength to concrete 3x the amount as steel. The only way to pull out the bar is to break the concrete itself.


Wherever you find concrete, you use RPM GFRP. The applications are endless.

RPM GFRP is suitable for use wherever concrete needs to be reinforced. Whether it is non-structural, structural or custom products, RPM GFRP can provide the rebar to meet your needs.

Because of the non-corrosive nature of fiberglass rebar, RPM GFRP is especially important to use in coastal areas to avoid concrete spalls and save on costly repairs.
