Glass fibre-reinforced polymer tendons for bridge

[foreng]

I am currently designing a stress laminated timber bridge and happened upon the concept of using GFRP (Glass fibre-reinforced polymer)tendons as the stressing element instead of steel rods. I have been trying to find a supplier but have been unsuccessful. Does anyone know where I might find a supplier (in Canada - west if possible, but US as well)

PS the product does appear to be also used in the geotechnical realm for slope stabilization if this helps.
