  • PC strand coated with rust inhibitor and method for producing the same
    Patent number: 5683642
    Abstract: A PC strand is formed by twisting peripheral wires made of deformed PC steel wires around a core, and allowing rust inhibitive material of thermoplastic resin to permeate into voids defined among the core and peripheral wires by use of an extruder. Since at least one of the core and peripheral wires is made of a deformed PC steel wire having an uneven outer surface, the thermoplastic resin can smoothly permeate deep into the inside of the PC strand.
