1. Production style: There are 8 kinds of steel fiber: flat head steel fiber, needle-flat steel fiber, corrugation steel fiber, undee steel fiber, micro-steel fiber, concave-flat steel fiber, stainless steel fiber. Also we can produce the fiber according to customer requirement regarding the diameter, length, shape and others 2. Length: 13-60mm 3. Diameter: 0.22-1.0mm 4. Tensile strength: 800-2500mpa 5. Standard: These products meet the requirements of astm a820 type i 6. Technical advantages: A. Easy dispersing, no balling and caking, distributing uniformly B. Greatly increased concrete ductility C. Greatly increased concrete tensile strength D. Increase anti-cracking E.Reduce the crack space F. Increase shear strength of component G .Increase shock-shear strength of slab - column structure H.Increase partial compressive strength I.Increase anti-earthquake and anti-blast J.Increase anti-abrasion and anti-cavitation erosion K. Increase prestressed unit anti-crack and bearing capacity L.Increase bending resistant, anti-shear fatigue m . Increase component shock strength 7. Economic benefits: A. Can extend the using life of project B. Can reduce the thickness of concrete and save the quantities of concrete under the same intensity C. Can take place of steel totally or partially D. Replace in concrete the traditional mesh reinforcement. E. Can reduce the workload of project, shorten the processing period, save the cost of project Packing :damp-proof poly bag, n.W 25kg/bag or 20kg/bag;40 bags/pallet or 50bags/pallet(1000kg/pallet), With plastic pellicle for out packing to protect the pallet or according to customer's requirements
