Steel fiber refers to fibers with a length-to-diameter ratio of 40 to 80, which are produced by cutting fine steel wires, cold-rolling steel strip shearing, ingot milling, or rapid cooling of molten steel. When the fiber cross-section is not circular, the diameter is calculated based on the equivalent circular area of the cross-section.

Steel fibers produced through different manufacturing methods exhibit varying properties. Although steel fibers have been in existence for a short time, their applications are increasingly widespread and the variety is expanding.

Steel, with cut-to-length steel fiber widely used due to its high tensile strength. Made from low-carbon alloys and produced using cold drawing techniques below the metal crystal temperature, these cut-to-length steel fibers can achieve a tensile strength of up to 1150-3000MP. They are extensively applied in reinforcing industrial floors (logistics, cold storage, outdoor, warehousing) and improving cracking conditions.
