TieTecGlass fiber reinforced polymer connector

For insulated precast sandwich panels

TieTec is a precast concrete sandwich panel connector that combines the mechanical properties and the thermal efficiency of ASTEC Glass Fiber Reinforced Polymers (GFRP) bars.

The use of TieTec is an innovative way to produce precast sandwich panels in a faster and more economical way compared to other methods.


Product features

  • Made of corrosion resistant material leading to slimmer panels.
  • Manufactured with optimum bonding with concrete thanks to dual surface deformation and sand coating.
  • No magnetic interference. No electrical conductivity.
  • Stronger than steel, therefore fewer number of ties are needed compared to other methods.
  • Lighter than other connectors and easier to install, leading to higher sandwich panels productivity.
