1.1 通过焊接制造的钢组件和子组件，如复合结构构件、窗扇、焊接件等，在制造后进行热浸镀锌，由于镀锌操作中的加热和冷却，材料会发生翘曲和变形，尤其是当有必要对组件进行多次浸渍以覆盖整个表面时。 1.2 本规范适用于英寸磅或国际单位制。英寸磅和国际单位不一定是精确的等价物。在本规范文本中，在适当的情况下，国际单位制显示在括号中。 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 Steel assemblies and subassemblies fabricated by welding, such as composite structural members, sash, weldments, etc., that are to be hot-dip galvanized after fabrication, are subject to warpage and distortion of the material due to the heating and cooling integral to the galvanizing operation, particularly when it is necessary for the assembly to be dipped more than once to coat the entire surface. 1.2 This specification is applicable in either inch pounds or SI units. Inch pounds and SI units are not necessarily exact equivalents. Within the text of this specification and where appropriate, SI units are shown in parentheses. 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.
