PC Strand (LRPC)

PC Strand (Prestressed Concrete Steel Strand) is a high-tensile twisted steel cable composed of 2, 3, 7, or 19 high-strength steel wires, stress-relieved (stabilized) specifically for prestressed concrete and heavy infrastructure applications.

Classifications:
- By Wire Count: 2-wire, 3-wire, 7-wire, and 19-wire steel strand.
- By Surface Morphology: Smooth steel strand, indented/scoring strand, mold pulling (compacted) strand, and epoxy resin coated steel strand.
- Tensile Strength Levels: 1860 MPa (most common), as well as 1720 MPa, 1770 MPa, 1960 MPa, 2000 MPa, and 2100 MPa.

Main Characteristics & Benefits:
High tensile strength, superior stress-relaxation performance, and excellent axial straightness. Galvanized steel strand is commonly used in tie-rods, cables, and external pre-stressing tendons for major bridge projects.
