1.1 本规范涵盖承载（横向和轴向）施工组件中的冷弯型钢结构框架构件（基础钢厚度不小于0.0329 in.（0.836 mm））。附加工程产品中允许使用厚度较小的钢材。 1.2 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。 1.3 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 cold-formed steel structural framing members (with a base steel thickness of not less than 0.0329 in. (0.836 mm)) in load-bearing (transverse and axial) construction assemblies. Steel of lesser thickness shall be permitted in additional engineered products. 1.2 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. 1.3 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.
