LRPC Strand (Low Relaxation Prestressed Concrete Strand) is a high-tensile steel strand used in prestressed concrete applications to provide superior strength and load-bearing performance. It is manufactured from high-carbon steel wires twisted together and processed to achieve low relaxation properties, ensuring minimal loss of prestressing force over time. LRPC strands are identified by their nominal diameter, tensile strength, and standard specifications, with weight based on strand size and length.
