   Be careful, some physical properties are worse, which can cause design issues. Also look at stainless steel - it's thermally much better than steel. Or steel fibers.

   Thanks Jon R!

   I may use both. I don't understand how you work with fiberglass rebar when you have to raise it to 200C to bend it? Anyway, I think I may have a special use for fiberglass rebar because of it's insulating characteristics. I will post a detail with that in it soon. As soon as I get my wind back. I have been on a roll today...

   It looks like you factory order the bends you need. Or order the special type that can be heated and field bent.

   I haven't used GFRP personally, but I did a bit of research on it a while back. I believe the main downfall is that it stretches somewhere around 4-5 times as much as grade 60 rebar, though I'm sure that amount is variable. That leads to wider cracks, more displacement, and as a result lower durability in the long run, so you have to use a higher % area of GFRP, congesting the volume, etc..

   Tyler Ley has a good set of videos on it, search for his channel on youtube, it's full of high and low level concrete info.
