Composite FRP

Abour FRP

Dextra engineers and manufactures innovative structural solutions based on high-tensile FRP (Fiber Reinforced Polymer) bars and profiles. Those solutions can be either made Glass-Fiber based (GFRP) or Carbon-Fiber based (CFRP).

What is ASTEC® FRP?

ASTEC® is Dextra’s trademark promoting unique FRP solutions developed and manufactured by Dextra. The brand ASTEC® is for our customer the guarantee of high performances and compliance with the world's most stringent requirements.

Why using FRP?

Applications made with composite FRP material usually take advantage of the following material characteristic:
  • Light weight compared to steel while offering very high-tensile performances.
  • Fully resistant to corrosion.
  • Cut-able by standard earth removal equipment and Tunnel Boring Machines (TBMs).


Product features

  • ASTEC CFRP Repair & Strengthening range is available in 3 forms: laminate, tape and rod.
  • Laminate: 50 or 100mm width with thickness of 1.4mm for an ultimate tensile load up to 336 kN.
  • Tape: 16mm width and available in two thicknesses foran ultimate tensile load of 140 kN.
  • Rod: 3 diameters up to 218 kN ultimate tensile load capacity. Our rod solution features innovative connectors to allow the installation as PT applications.
  • Designed as per ACI440.2R-08 , ACI440.74, ACI-440.7R and FIB Task group 9.3. Tested as per ACI 440-3R-12.


Grade material
High weight to strength
4x the performance of steel for only 25% of the weight.
Minimum visual impact
Extremely thin solutions that can be hidden into cut grooves.


  • Fast to install.
  • Cost effective.
  • Durable: no maintenance, no post inspection.
  • Limited visual impact, thanks to a compact size and applications where the CFRP is hidden into a cut groove.
  • Can be installed in all weather conditions.
  • Also fits wooden structures.
