Round Crimped Steel Fibres
Round Crimped Steel Fibres
Round crimped steel fibres exhibit a waveform or crimped profile in a generally round cross-section. This profile enhances mechanical interlock with concrete, enabling better stress transfer, elongation in pullout and crack control capacity. Their geometry allows for more consistent dispersion, improving toughness, load transfer, and long-term durability, reducing fiber clustering and enabling reliable performance in both cast and sprayed concrete mixes. Round Crimped Steel Fibers are a cost-effective and versatile solution for general-purpose concrete reinforcement.

Key Features
Improved Mechanical Bond
Crimped profile adds small bends to increase pull-out resistance.
Uniform Dispersion
Round cross-section enables easier mixing and flow.
Flexible Use
Useful in industrial slabs, precast, overlays, and large volume pours.
Cost-Efficient Performance
Better toughness and post-crack strength without overly complex hook geometry.
Applications
Flooring and pavements where toughness underload matters
General civil structures
Precast segments and concrete blocks
Slope stabilization
Hydraulic and retaining structures
Precast panels, beams, pipes
Large mass concrete pours where ease of mixing is important
Shotcrete (depending on the sprayability of crimped fibres)
