Next-Generation Rebar Alternative: GFRP

GFRP (Glass Fiber Reinforced Polymer) is a non-corrosive composite reinforcement material made from glass fibers. It is approximately 25% lighter than steel and offers superior corrosion resistance while maintaining greater strength than traditional rebar. By reducing carbon emissions and lowering maintenance costs, GFRP delivers a service life exceeding 100 years.

Productivity & Workability

Lightweight

About one-fourth the weight of steel rebar, making handling and transport much easier.

Faster Installation

Reduces installation time by up to 30%.

Safety

Superior Corrosion Resistance

Does not rust even when exposed to water, salts, or chemicals, completely preventing rebar corrosion problems.

Extended Service Life

Extends the lifespan of structures in corrosive environments by over 100 years.

Environmental Sustainability

Low Carbon & Energy Footprint

Requires less energy during production than steel and produces far lower CO2 emissions.

Sustainable Infrastructure

Longer structural lifespan reduces material waste and resource consumption.

Cost Efficiency

Reduced Life-Cycle Cost (LCC)

Minimizes long-term maintenance expenses due to excellent corrosion resistance

Low Maintenance Requirement

Corrosion resistance significantly cuts repair and upkeep costs.

In only 20 years, severe corrosion develops.

Cracking and Damage in Concrete Caused by Steel Corrosion

As steel corrodes, the rust that forms expands in volume, creating internal tensile stress within the concrete.
This stress leads to cracking, spalling, and delamination. A phenomenon known as concrete deterioration due to corrosion.

To build safer, longer-lasting, and more sustainable concrete structures, GFRP Rebar is being rapidly adopted across a wide range of applications, establishing itself as the new standard for future infrastructure.
