In order to suppress the expansion of cracks inside the concrete, reducing the brittleness of concrete to improve its durability, mixing steel fiber into concrete.

   The straight steel fiber belong to micro steel fiber, the length is short and the wire diameter is thinner, what’s more, the tensile strength is higher than other low carbon steel fiber.

Material: round cold drawn wire.             

Wire diameter(D):0.3-0.4mm  (±0.02mm)                        

Fiber length(L):6-12mm     (±0.02mm)   

Aspect ratio L/D: 20-40

Shape: straight

Tensile strength:>1200 Mpa

Appearance: galvanized,bright and clean wire
