Crimped Steel Fiber

PSI CRIMPED STEEL FIBER are low carbon, cold drawn steel wire fibers designed to provide concrete with temperature and shrinkage crack control, enhanced flexural reinforcement, improved shear strength and increase the crack resistance of concrete. PSI Crimped Steel Fiber complies with ASTM C1116, Standard Specification for Fiber Reinforced Concrete and Shotcrete and ASTM A820, Type V, Standard Specification for Steel Fibers for Fiber Reinforced Concrete. These steel macro-fibers will also improve impact, shatter, fatigue and abrasion resistance while increasing toughness of concrete. Dosage rates will vary depending upon the reinforcing requirements and can range from 25 to 100 lbs/yd³ (15 to 60 kg/m³).

Features & Benefits

  • Increases impact, shatter and abrasion resistance of concrete
  • Reduces segregation, plastic settlement, and shrinkage cracking of concrete
  • Provides three-dimensional reinforcement against macro-cracking
  • Increases overall durability, fatigue resistance and flexural toughness
  • Reduction of in-place cost versus wire mesh for temperature / shrinkage crack control
  • Easily added to concrete mixture at any time prior to placement


  • Commercial and industrial slabs on ground
  • Bridge decks, overlays and pavements
  • Precast concrete applications
  • Shotcrete, tunnel linings and slope stabilization
  • Mass concrete and composite deck construction

Specifications / Compliances

  • ASTM C1116
  • ASTM A820


PSI Crimped Steel Fibers are packaged in 55 lb (25 kg) bags; 2200 net lbs (1000 kg) per pallet.
