Precast Structures
Precast Structures
Steel Fiber Reinforced Concrete (SFRC) is revolutionizing the precast industry. Be it tunnel segments or façade panels, box culverts or breakwaters or even Jersey Barriers, the integration of steel fibers enhances structural integrity, controls shrinkage cracks, and improves post-crack behavior ensuring durability. Stewols Bansal’s SHAKTIMAN® Steel Fibers are trusted by leading precast manufacturers for delivering consistent, high-strength performance with streamlined production workflows.
Key Benefits
Shrinkage Crack Control
Reduces early age and plastic shrinkage cracking.
Enhanced Load bearing
Improves ductility and energy absorption under loads.
Eliminates or Reduces Rebar
Simplifies mold design and speeds up demolding cycles.
Superior Finish
Ideal for architectural precast elements needing a smooth surface.
Dimensional Accuracy
Enables precision in modular construction with repeatability.
Casting Flexibility
Casting can be done on site or elsewhere and transported to site.
Easier Transportation
Tough integration allows casted elements to be transported without (or with minimal) damage.
Precast Tunnel Lining Segments
Box Culverts and Utility Tunnels
Retaining Wall Panels
Precast Road Barriers (e.g., Jersey barriers)
Architectural Precast Panels
Light Poles and Foundation Blocks
Drainage Channels and Deck Slabs
Breakwaters
Typical Applications
Why SFRC in Precast?
Traditional rebar cages in precast increase complexity, production time, and material usage. Steel fibers streamline the process especially in smaller, intricate, or thin-walled elements where conventional reinforcement placement is inefficient. Benefits include:
Up to 25% faster production cycles
Reduction in steel congestion, improving concrete flow and compaction.
Improved mechanical anchorage, ideal for dynamic or impact loads.
