PC Strand

7-wire prestressed concrete strand used in fields such as bridge beam, reinforced concrete prefabricated building elements, silo manufacturing and ground anchoring applications can be produced in accordance with ASTM, EN, BS and other national standards.
 

The prestressed concrete strand with low relaxation properties is appropriately taged for identification and traceability and is packaged and ready for shipment according to customer demands.
 
Low relaxation propertie of PC Strand provived by relieving the stresses of high carbon, chromium and vanadium alloyed wire rods after cold drawing by a thermomechanical process. In prestressed systems, the pre-tensioning obtained at first decreases over time, in particular due to the relaxation of the tensioned steel over time. For this reason, the low relaxation of the prestressed concrete strand is one of the most important criteria considered in such applications.
