Tested in the best laboratories according to ASTM-C1399 standard of flexo-tensile tests and study of average residual resistance. FLEXOFIBERS MACRO is the only 100% recycled metal fiber that provides the same benefits of other metal fibers. Additionally, it is a fiber composed of high-quality steel wires with a small diameter, thus achieving a large number of filaments per unit of weight and better distribution throughout the mass of concrete. Less space between filaments generates greater efficiency and redistribution of internal efforts.
