What items need to be tested for steel structures
1、 Non destructive testing: ultrasonic testing, radiographic testing, magnetic particle testing, penetrant testing.
2、 Performance testing: Steel mechanics testing, fastener mechanics testing.
3、 Metallographic analysis: microstructure analysis, microhardness testing, etc.
4、 Chemical composition: Conduct chemical composition analysis on the steel used in steel structures.
5、 Paint testing: Testing the paint used for surface coating of steel structures.
6、 Stress testing: Testing and monitoring the stress changes in key areas during the installation and unloading process of steel structures.
