Products

In collaboration with industry partners, load-transfer products and structural components composed of glass, carbon or aramid fiber-reinforced polymers (G-, A-, C-FRPs) are developed, taking advantage of the properties offered by FRP materials, such as high strength, low weight, low thermal conductivity, and resistance against aggressive environments.

GFRP-balsa sandwich bridge deck

– Bridge deck system with GFRP skins and balsa core
– Lightweight, prefabricated large-scale panels, rapid installation
– Road and pedestrian bridges

Multifunctional balcony connectors

– Thermally insulating balcony connectors for buildings
– A/GFRP loop, bar and sandwich components
– Low linear thermal transmittance

Strengthening of concrete flat slabs against punching shear

– Flexible CFRP strengthening loops
– Post-tensioned strengthening system
– Increased punching shear resistance of existing slabs

Ground anchors

– CFRP rock or ground anchors with up to 1000-kN capacity
– One or two CFRP strap-end anchor heads
– Resistance against aggressive environments
