Crimped steel fiber is a low carbon, cold-drawn steel wire fiber designed to provide temperature and shrinkage crack control, strengthen flexural reinforcement, increase shear strength and improve crack resistance of concrete. It has excellent tensile, bending and shearing strength, high tenacity, and resistance against cracking, impact and fatigue. Crimped steel fibers are low-carbon, cold-drawn steel wire fibers designed to provide temperature and shrinkage crack control, strengthen flexural reinforcement, increase shear strength, and improve crack resistance of concrete. Crimped steel fiber conforms to the standards outlined in 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 coarse steel fibers not only enhance impact resistance, shatter resistance, fatigue resistance, and abrasion resistance but also contribute to increasing the overall toughness of the concrete. The recommended dosage ranges from 25 to 100 lb/cubic yards (15 to 60 kg/m3), depending on the specific reinforcement requirements of the project. Crimped steel fiber is widely used for buildings, road surfaces, bridges, tunnels, airport road surfaces, water conservancy projects, military engineering, and all kinds of building products.
