Comparison and analysis of domestic and foreign testing standards for light steel keel and accessories used in suspended ceilings
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.
