Guy strand wire ropes are critical steel components used for guying and stabilizing tall structures like telecommunication towers. They typically consist of a single strand, with common constructions including 1x7, 1x19, 1x37, and 1x61. In the 1x7 construction, seven high-tensile strength, high-carbon steel wires are helically stranded, offering minimal flexibility and maximum tensile resistance. The wires are usually made from cold or hot-dip galvanized steel to enhance corrosion resistance. The nominal diameter of these strands varies widely, typically ranging from 3 mm to 40 mm. For instance, a 1x7 strand with a 12 mm nominal diameter can have a minimum aggregate breaking force of approximately 124 kN for a wire tensile grade of 1570 MPa.

The mechanical properties are defined by the wire tensile strength grade, commonly classified at levels such as 1370, 1570, and 1770 MPa. These grades directly determine the ropes minimum aggregate breaking force. For a wire rope of a given diameter, increasing the tensile grade from 1370 MPa to 1570 MPa can raise the breaking force by approximately 15%. Proper selection of diameter and grade follows design standards like TIA-222, considering applied loads wind, ice, seismic and appropriate safety factors. The final design must ensure the induced stress in the strand remains below the allowable limits specified by these standards.You can order and buy PC strand from Iran by contacting us through whatsaap and email.
