Cold Drawn end hook compared to other forms of fiber, its tensile, compressive, flexural strength and anchoring strength has greatly improved for a number of key projects, seismic blast-resistant structures. The homogeneous addition of steel fiber concrete, steel fiber reinforced concrete form, can construction project reinforced concrete thickness reduced by half, only reinforced matrix cracking, impact, tensile, bending, shear, friction, etc. performance, but also can bring significant economic benefits for road, highway slope, bridges, tunnels, airport runways, municipal engineering covers, ports, railway sleepers and so on. . .
