通过对吊顶用轻钢龙骨及配件相关的国内外标准进行研读和讨论，并对基材、外观质量、尺寸公差、耐腐蚀性能、力学性能技术要求及试验方法进行对比，分析不同国家标准的差异性，为龙骨产品在国际贸易及合作中的发展提供参考，同时也为国标的修订提出改进力学性能、防腐蚀性能技术要求等合理化建议。

The domestic and foreign standards related to light steel keels and accessories for suspended ceilings are studied in this paper. And the technical requirements and testing methods are compared for materials, appearance quality, dimensional tolerances, corrosion resistance and mechanical properties. The differences are analyzed among different standards. This study provides reference for the development of keel products in international trade and cooperation in the future. At the same time, some rational suggestions are proposed for improving the technical requirements of mechanical performance and anti-corrosion performance for the revision of the national standard.
