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.
