1.1 本规范涵盖了金属涂层钢丝结构股，用于需要高强度、高模量、多钢丝受拉构件作为结构组成部分的情况。钢绞线可采用平行或螺旋钢丝结构。 1.1.1 钢绞线有几种金属涂层等级和两种强度等级，如第节所述 4. . 1.2 绞线始终配有A级重量锌或锌铝合金涂层导线。作为一种选择，它可以配备B级重量或C级重量镀锌外导线。 1.3 以英寸-磅为单位的数值应视为标准值。 括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers metallic-coated steel wire structural strand, for use where a high-strength, high-modulus, multiple-wire tension member is desired as a component part of a structure. The strand is available with parallel or helical wire construction. 1.1.1 The strand is available with several metallic coating classes and with two strength grades, as described in Section 4 . 1.2 The strand is furnished with Class A weight zinc or zinc-aluminum alloy-coated wires throughout. It can be furnished with Class B weight or Class C weight zinc-coated outer wires as an option. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
