- 摘要：
- <p>A PC strand (1) is formed by twisting peripheral wires (3) made of deformed PC steel wires around a core (2), and allowing rust inhibitive material of thermoplastic resin to permeate into voids defined between the core (1) and peripheral wires (3) by use of an extruder. The core (2) may be deformed instead of the peripheral wires (3). Since at least one of the core (2) and peripheral wires (3) 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. <IMAGE></p>
