Steel Fibers

Steel Fibers

High-tensile steel filaments with folds at their ends, made with cold-rolled high carbon wire, used as reinforcing steel in concrete structures.


  • Low carbon steel with polished and shiny finish
  • Straight with hook end
  • 20-kg boxes


  • Better control of cracks
  • Greater impact-resistance
  • Technical assistance to classify fibers according to each project
  • Cost reduction in labor and materials


  • Industrial floors and pavements
  • Shotcrete
  • Prefabricated elements

According to manufacturing standards

  • ASTM A-820 “Standard Specification for Steel Fibers for Fiber Reinforced Concrete”.
  • EN 14889-1 “Fibers for concrete. Part 1: Steel fibers. Definitions, specifications and conformity”.
  • ISO-13270 “Steel Fibers for concrete – Definitions and specifications”.
