ASTEC™ FRP rebar for permanent applications

ASTEC GFRP rebar for permanent applications

Corrosion-free alternative to steel rebar

GFRP rebar allow contractors to substitute steel rebar with composite non-corrosive and non-metallic reinforcement.ASTEC Glass Rebar can be used for both new construction or as a strengthening material.  ASTEC GFRP rebar solutions offer very high tensile performances for a light weight: up to 8 times the performance/weight ratio of steel.

Since 1996, Dextra has established new standards becoming the worldwide reference in FRP rebar manufacturing, made by pultrusion. Precursor of this technology, we have successfully supplied thousands of projects all around the world.

ASTEC rebar are available in various grades and sizes. Bars are available in various sizes from 6mm to 51mm (#2 to #16) and in 2 grades. Splicing systems are also available. Taylor-made shaped can also manufactured.

For more information, please refer to our technical documentation. Dextra design team is also available to support you in the design and optimization of your GFRP rebar use.
