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 . Chemical property: C:0.07-0.12% Si:0.10%max Mn:1.25%max S:0.05%max P:0.10%max Shape:Bow,crimped(corrugated,rippled),endhooked, flat-slight twisted shape Size:Length 15mm,25mm,30mm,40mm,50mm 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.
