Crimped Steel Fiber

PSI CRIMPED STEEL FIBER are low carbon, cold drawn steel wire fibers designed to provide concrete with temperature and shrinkage crack control, enhanced flexural reinforcement, improved shear strength and increase the crack resistance of concrete. PSI Crimped Steel Fiber complies with ASTM C, Standard Specification for Fiber Reinforced Concrete and Shotcrete and ASTM A820, Type V, Standard Specification for Steel Fibers for Fiber Reinforced Concrete. These steel macro-fibers will also improve impact, shatter, fatigue and abrasion resistance while increasing toughness of concrete. Dosage rates will vary depending upon the reinforcing requirements and can range from 25 to 100 lbs/yd³ (15 to 60 kg/m³).

Generally, fibers include steel fiber, glass fiber, glass fibers, synthetic fibers and natural fibers. Each fiber has they own superior performance in different fields. But steel fiber is a new fiber-reinforced concrete used in industry. In some specific circumstances, steel fiber is completely instead of steel rebars in concrete.

In contract to rebar, steel fibers makes difference in controlling cracks, lowering the possibility of maintenance and saving your budget.

• Strengthen the initial crack strength.
• High fiber counts intercepting micro-cracks and preventing crack propagation by limiting tensile strength.
• Uniform distribution of steel fiber throughout the matric reinforce isotropically ensures no weak plane for a crack to follow.
• Flexural strength allows for a thinner slab, about 25% thinner than conventional methods.

How steel fibres save your time and MONEY?

• Significantly reduced risk of cracking.
• Reduced spalling joint edges.
• Stronger joints.
• High impact resistance.
• Greater fatigue endurance.
• Reduced maintenance costs.
• Longer useful working life

The quantity of steel fiber in concrete

The amount of steel fiber added to concrete is a called "volume fraction" (Vf). The volume fracture ranges from 0.1% to 0.3%. The use of steel fiber is a small quantity thus it is very cost-effective.

Based on the advantage above, steel fiber is an ideal industrial product for purchasers.
