LRPC (low relaxation prestressed concrete) strand
What it is
Low Relaxation Prestressed Concrete strand - high-tensile steel wire helically wound and stress-relieved so it loses very little tension over time. It is tensioned inside concrete to pre-compress the structure
It is the enabling material for long-span bridges, metro viaducts, flyovers, sleepers and prestressed buildings
Impact on industries
- Directly geared to the infrastructure cycle - every metro viaduct, bridge and flyover consumes LRPC, so government capex converts into volume
- Specification and certification requirements exclude casual entrants, so competition is narrower than in plain wire
- Demand is entirely project-linked and lumpy, and slips whenever infrastructure execution slows or funding cycles pause
- Order flow is largely tender-driven, so realisation is capped by lowest-price award among qualified bidders
