Micro Copper Coated Steel Fiber for Precast Concrete

Introduction of micro steel fiber:

Micro steel fibers are made of copper-coated steel wire which is the most important materials of UHPC. BecauseUHPC has the 
features of 
extreme high strength. It is a good and a new kind of construction materials. Micro steel fiber is widely used in the 
high speed railway slab, expressway, RPC coverplates and UHPC constructional components.

Applications of micro steel fiber :

UHPC Concrete
Railway Sleepers
Jointless connection industrial floor

Micro steel fiber benefits:

Good dispersion performance in concrete
Insist impact,fatigue
Significantly improve the toughness of concrete
Shrinkage control and ductility in the reinforcement concrete

What is the use of steel fiber in concrete?

Steel Fibers are used as sprayed concrete (shotcreting), 
slope stabilization, precast concrete production tunnel and mining shafts and underwater 
concrete reinforcement. Steel Fibres are also popularly used in manufacturing precast walls, 
overlays, manhole covers, piles & pillars.
