Steel fibres enhance post-cracking strength and toughness, allowing concrete to sustain higher loads even after initial cracking.
Independent testing and research (including studies by Prof. Nemkumar Banthia, University of British Columbia, Canada) have demonstrated that:
ARS testing confirms enhanced post-crack residual strength compared to plain concrete.
Unlike conventional 2D reinforcement (mesh), steel fibres provide distributed 3D reinforcement throughout the concrete matrix.
Reduces shrinkage cracks and improves fatigue, impact, and abrasion resistance (10–15 times improvement in impact performance in heavy-duty conditions).
Enhances structural ductility, leading to longer service life and reduced maintenance.
No requirement for mesh placing or cover blocks
Reduced labour requirement
Faster concreting cycle
Although initial cost may be comparable, lifecycle cost over 20–25 years is significantly lower due to reduced maintenance and repairs.
Typical dosage range:
12 kg to 50 kg per m³ of concrete
(Actual dosage depends on load condition, slab thickness, and structural design.)
With proper design and construction planning, SFRC floors and structures can achieve:
25–30 years of maintenance-free service life under heavy-duty loading conditions.
Steel fibres supplied by us have been used in numerous projects across India through Government-approved contractors and engineers for:
Manufactured in India
Conforming to ASTM A820 / A820M
Steel Fibres are high-strength, cold-drawn steel wire fibres used as dispersed reinforcement in concrete. When uniformly distributed in concrete, they provide three-dimensional reinforcement, enhancing post-cracking strength, toughness, impact resistance, and durability.
Designed for use in industrial floors, pavements, tunnels, precast elements, and heavy-duty slabs.

Steel Fibres tested and validated under ASTM A820 / A820M
Steel Fibre Reinforced Concrete provides:
WWM provides conventional planar reinforcement but lacks distributed crack control and post-crack performance.
For heavy-duty industrial flooring and load-bearing slabs-on-grade, Steel Fibre Reinforced Concrete offers superior structural performance, faster construction, and improved lifecycle value compared to Welded Wire Mesh, subject to proper structural design and dosage selection.
