Wirand® Steel Fibers

Wirand® Steel Fibers have been produced by Maccaferri for more than 25 years.  Wirand® steel fibers are manufactured with low carbon steel wire with high tensile strength resistance. Adding Wirand® steel fibers into the concrete mix provides new mechanical properties that can enhance structural applications. The Wirand® steel fibers can be included as a substitute for the common steel reinforcement, or as a complement, or for a better performance for strain that the common reinforcement can't absorb. The result is a more ductile concrete which is able to maintain a residual capacity in the post-cracking phase.

In mechanical and performance terms, by adding Wirand® steel fibers to the concrete mix you can:

  • Increase and get a more stable tensile strength under flexion load, which produces a ductile behavior
  • Increase impact resistance
  • Increase cyclic loads of resistance (fatigue effect)
  • Increase prevention of the plastic shrinkage crack
  • Increase the concrete performance against thermal variations
  • Get minor permeability

Wirand® steel fibers reinforce concrete products while saving time on labor. The use of Wirand® steel fibers in applications such as tunneling, industrial flooring, airport pavements, pre-cast and pre-compressed concrete represents an optimal, cost effective and technical solution.
