Low Relaxation Prestressed Concrete (LRPC) Strands In keeping with the demands of the international market, we have introduced Low Relaxation Prestressed Concrete (LRPC) Strands for the construction industry in 2001. A steel member that is prestressed and embedded in concrete, loses the initially applied stress exponentially with the passage of time. The single most important factor attributing to this loss in stress relaxation property of the steel itself. By treating the steel through a thermomechanical process known as stabilizing, the propensity of the steel to "relax" under a stressed condition is controlled to a great extent. Some of the main advantages that our customers derive by using low relaxation strands are listed below: Upto 10% reduction in steel requirement possible. Saving in number of anchorages, ducts, sheathings, wedges and labour resulting in overall reduction of project cost. Reduction in concrete requirement due to reduced size of structural members. Hot stretch process used during the manufacture of LRPC strandsproduces a nearly straight strand, thereby eliminating necessity for extra post straightening treatment. Applications Pre-stressed concrete girders for road, river & railway bridges and flyovers, pre-stressed concrete domes, slabs, silos, hangars, aquaducts, viaducts & railway sleepers.
