Steel fibre can be sorted into four models on the basis of different process : wiredrawn model , drawn-cut model , cut model and pared-cut model . There are five different shapes of steel fibre ( more than 20 specifications ) available : flat-slight twisted shape , waving shape , hook-ending shape , bowing shape and extruding shape .
As different resource and materials are required , steel fibre can be also sorted into two models : carbon steel fibre and specific steel fibre. Some cold-roll iron such as Q195 , Q215 , Q235 are used for carbon steel fibre; stainless steel 304# or the material specially ordered by customers are used for specific steel fibre .

Thickness 0.3mm,0.4mm,0.5mm,0.6mm,0.7mm,0.8mm with tolerance +/- 0.1mm
Applications:
Steel fibre now becomes a ideal material for reinforced concrete in the world , Owing to its high strength , good property of anti-attrition . With it's good property of stickiness , steel fibre can increase concrete components' intensity and lengthen their duration.
It will much strengthen crack resistance,rupture resistance,strain resistance and fatigue resistance by blending the fiber and concrete in a certain ratio.It is widely used in highway,bridge,funnel,runway and construction of tall building as well as furnace of shock resistance and high temperature.
