Steel fiber is a high-strength reinforcement material made from carbon steel, stainless steel, or other alloys, cut into short, discrete lengths. When mixed into concrete, these fibers disperse uniformly and form a three-dimensional reinforcement network. This significantly improves the concrete’s tensile strength, flexural strength, toughness, crack resistance, and durability.

Compared with traditional steel bars or welded wire mesh, steel fiber reinforcement provides superior crack control, distributes stresses more evenly, and enhances the long-term performance of concrete in demanding applications such as industrial floors, shotcrete, precast elements, highways, bridges, and hydraulic structures.
