All RockStirrups® are custom made and are only sold for use with RockRebar®
RockStirrups® are designed to be the lateral support to RockRebar®, the method by which 90-degree corners are produced and the containment cages to assemble beams and columns. RockStirrups® are produced through the application of 360-degree layer wraps of continuous basalt fiber and epoxy tapes. The result is fully closed Basalt (BFRP) Stirrup where the corners are as strong as the sides. This layer wound continuity of basalt fibers is a clear performance advantage in the efficiency of the composite reinforcement .
