The hook at both ends ensure the ideal binding between the steel fiber and the concrete, making it possible for the steel fiber to play the most effective role without any lumps as a result of the mixture between steel fiber so as to make best use of the tensile strength of the steel fiber.

    Made of cold-drawn steel wire, cold-drawn galvanized steel wire and stainless steel wire, the steel fiber at diameter of 0.4-0.8mm is cut into the required short sections. The tensile strength, as highly as 1000-2000MPa, is distinctly superior to the steel fiber processed in other ways. To improve the cohesion between the steel fiber and the concrete, the appearance can be modified.
