  • Exceptional resistance to water and salts and provides excellent resistance to a range of chemicals
How it works

Thinking Smarter and Greener with GFRP Reinforcement Technology

With tensile strength 2x that of steel and non corrosive, Casta Smart-Bar™ glass fiber-reinforced polymer (GFRP) rebar is designed to replace steel reinforcement in almost any application both as primary or secondary reinforcement. It has been used globally for a number of years now in a range of applications to major infrastructure projects as well as in highly corrosive environments including underwater structures, coastal environments and industrial sites.

Smart-Bar is ACI, ASTM and CSA Grade III compliant making it easy for designers engineers to change from traditional rebar to GFRP rebar.

Why use Smart-Bar™?

The challenge for asset owners, design and engineering consultants is to gain the best design life cycle for a project, which has seen GFRP rebar prove itself, providing a competitive and sustainable advantage. Issues of corrosion are paramount, particularly in marine and coastal areas teamed with a warm environment.

Using Smart-Bar and Smart-Dowel as an alternative reinforcement to steel eliminates the risk of corrosion and associated costs. As there is no concrete spalling, maintenance and corrosion protection measures are not required. Based on life cycle cost analysis, the use of Smart-Bar provides competitive prices, zero maintenance, excellent durability, and long design life.

It has a high tensile strength (2x greater than steel), high modulus, and a range of physical and mechanical advantages, Smart-Bar leads the world in durable rebar.
