LRPC / HT Strands

LRPC, an acronym for Low Relaxation Pre-stressed steel strands, represents the phenomenon where pre-stressed steel strands gradually release their initially applied stress in a mathematically proportionate manner as they become embedded in concrete. The primary contributing factor to this stress reduction is the inherent property of steel known as stress relaxation. Through a thermo-mechanical process referred to as ‘stabilizing,’ steel’s tendency to “relax” under a stressed condition is effectively controlled. Low relaxation ensures that there will be no significant loss of tension over time, resulting in a sustained compressive force on the concrete. Our Prestressed Concrete Steel Strands when embedded in concrete, release some applied stress exponentially. Low relaxation makes sure that, over time, there is negligible loss of tension. This gives lasting compressive strength to concrete, making it more durable.
