More Details: Based on the importance of bolt fasteners for the highway traffic guardrails in service, the current situation, technical standards and applications of the anti - corrosion technology for guardrail bolts were reviewed in this paper. The technical defects of using hot dip galvanizing to treat the bolt fasteners and technical advantages of using mechanical galvanizing to treat them were pointed out based on an analysis. The quality problems of the current industrial mechanical galvanized guardrail bolt fasteners, the current technical standards for surface anti - corrosion of guardrail bolt fasteners, and the problems and technical obstacles in the implementation of such standards were also pointed out. Based on analysis and induction, suggestions on further research and work were put forward in the aspects of the correlation between the process of mechanical galvanizing and the coating density and zinc quality deposited, the main quality indexes of coating as well as their determination and the practicability of determination, and the differences of coating quality on the main test surface and thread. It was hoped that these suggestions would promote the development of anti - corrosion technology for highway guardrail bolt fasteners in China.
