Definition

STEEL FIBER is kind of advanced composite material, which is most widely used as concrete reinforcing material in construction and engineering work nowadays. Certain dosage of steel fiber in concrete can cause qualitative change on concrete's physical property, greatly increasing cracking resistance, impact resistance, fatigue resistance, bending resistance, tenacity,durability and other properties.

Steel fiber types

The types of steel fibers are defined by ASTM A820:

Type I: cold-drawn wire

Type II; cut sheet

Type III: melt-extracted

Type IV: mill cut

Type V: modified cold-drawn wire

Application：

Concrete reinforcing material in construction and engineering work

Roads and bridges,tunnels and culverts, RPC cover plate

Industrial floorings, shortcrete, high-abrasive material, prefabricated concrete components

Water conservancy ,hydroelectric power projects,anti-aircraft projects, port large dam, mines

City pit cover, large water project, containers yard, vessel producing field and other fields of engineering etc.
