There are no specific requirements for the service life of steel structures in the code, but in the structural design, according to the loaded code, the load statistical value of 50 years as the basic cycle is basically adopted, that is, the probability that the normal design steel structure will be damaged due to excessive load within 50 years is very small.

Rust removal and coating of steel structures is a work easily ignored by steel structure contractors and is also a weak link in steel structure engineering construction. If this phenomenon is not corrected, it will have a great impact on the construction quality of the steel structure, because the quality of rust removal and painting will directly affect the maintenance cost of the steel structure during its future use, as well as the service life of the steel structure project, the safety of the structure, and the fire resistance time in case of fire (fire-resistant painting).
