Either Straight or Deformed Steel Fibers Used in Shotcrete or Concrete

Steel fiber is to control concrete cracking and prevent water from bleeding.

steel fiber is usually used in concrete or construction projects in order to control cracking due to plastic shrinkage and drying shrinkage. Additionally, the use of steel fiber in tunnelling projects are increasing.

In some specific circumstances, steel fiber can replaces traditional steel reinforce rebar in concrete. Steel fiber produces great impact-resistance, abrasion resistance and shatter-resistance.

Steel Fiber Feature

1. Enhanced structural strength.
2. Enhance impact– and abrasion–resistance.
3. Enhance freeze-thaw resistance.
4. Reduce crack widths & control the crack widths tightly.
5. Reduce steel reinforcement requirements.
6. Common use in industrial flooring.
7. Easy to handle.
