The "Berpais" steel fiber is made of high-quality wire rods as the substrate, using a unique process of pure cold drawing technology, with a tensile strength of 800-3000MPa, greatly improving the tensile performance of steel fiber products. The "Berpais" steel fiber series products can be widely used in the field of concrete reinforcement in construction, effectively hindering the expansion of micro cracks and the formation of macro cracks inside concrete, significantly improving the tensile, bending, impact, and fatigue properties of concrete, making it more ductile and achieving long-term, safe, and stable use efficiency.
