Heads

In lieu of J-bends or L-bends, anchor heads are used installed on the 60GPa Grade III bar to provide anchorage. This provides some advantages in areas of congested reinforincing while one of the other benefits is in the case of long lengths of straight bar where typically a formed bend would have to be spliced due to some limitations in the process of producting GFRP bends. A head could then be placed on one or both ends of long lengths of bar.
