Bent bars and stirrups

Bent bars and stirrups

ComBAR® bent bars and stirrups are produced by bending a specially made polypropylene conduit pipe filled with glass fibres and a vinyl ester epoxy resin into the desired shape. These raw bars are then thermally cured. This procedure allows for a high fibre content and a nearly parallel alignment of the fibres in the bent portion of the bars, resulting in high strength and a modulus of elasticity similar to that of straight ComBAR® bars.

ComBAR® bent bars can be produced in all bending shapes (2D) known for bent steel rebar. Spirals, 3D bars and bending in two directions are also possible. The smallest pin diameter is seven times the nominal bar diam- eter. Bent ComBAR® bars are hardened in a form with maximum dimensions 1.95 by 3.15 m
