BUNDREX Steel Fiber

​Aspect Ratio(L/D)

Length(mm)

C(Bundle) / L(Loose)

H(Hooked-end) / A(Arched)

The aspect ratio increase with smaller diameters and longer lengths.

As aspect ratio increases, the reinforcement effect is better, while workability is less.

That is why it is important to choose the proper aspect ratio of the steel fiber according to various site conditions.

​BUNDREX pRODUCTS LIST

BUNDREX steel fibers are produced using the ASTM-A820 Type1 method, a cold drawn wire technology.

BUNDREX produces steel fibers with varying tensile strengths from 1,050MPa to 2,400MPa.

Tensile Strength(TS) = Breaking load(P) / Cross Section(A)

The greater the tensile strength, the better the reinforcement effect of concrete.
