Indented PC Strand
The indented PC strand is a qualityconstruction steel rope. Like the spiral PC strand, it features high bond strengthto the concrete. It has found wide applications in PC hollow slabs, high-speedrailway sleepers, etc.

Our company strictly complies with the nationalindustry standards of different countries. Various quality tests need to becarried out before products leave the factory. Our indented PC strand can begrouped into three varieties based on the number of twisting wires: 2-wire,3-wire, and 7-wire. It comes in left-twist or right-twist knitting forms. The7-wire PC cable has a diameter of 8.0mm,9.3mm, 9.53mm, 11.1mm, 12.5mm, 12.7mm, 15.2mm, 15.24mm, or 15.7mm. Its tensile strengthcan be 1770MPa or 1860MPa. The 2-wire PC cable is supplied with a diameter of 7.6mm, 8.6mm, or 9.1mm.The 3-wire PC cable is available with 4.8mm, 5.2mm,5.8mm, 6.2mm, 6.5mm, 7.5mm,and 8.6mm. Boththe 2-wire and 3-wire PC ropes are provided with tensile strength of 1725MPaand 1860MPa.
