Application and specification of steel fiber

Steel fibre is shotcrete (spray concrete) with steel fibres added. It has higher tensile strength than unreinforced shotcrete and is quicker to apply than weldmesh reinforcement. Tradition rebars are generally used to improve the tensile strength of the conrete in a perticular direction. whereas steel fibers are useful for multidirectional. This is one of the reasons why steel fiber reinforced (Shotcrete form) concrete successfully replaced weldmesh in lining the tunnels and other place.

Grade: Q195,Q235,Q345, 330#, 310#, 304#, 446#,430# etc
Thickness: 0.25mm~0.8mm
Width: 0.5mm~5.0mm
Length: 20mm~45mm
Tensile Strength: 580Mpa~ 3000Mpa

Application: Steel fiber can be widely used in many industries. It have many advantage than tradition rebar.
• Improve structural strength
• Reduce steel reinforcement requirements
• Improve ductility
• Reduce crack widths
• Improve impact & abrasion resistance
• Improve freeze-thaw resistance
