As a crucial fastening component in the railway track system, the core function of railway spikes is to firmly anchor the rails to the sleepers or other load-bearing structures, so as to ensure that the track system has a stable structural state, good straightness and reliable safety performance. During the operation of railway trains, spikes play a decisive role. They must be able to withstand various external forces such as the weight of the train itself, the vibration and shock generated by the operation, and the stress caused by changes in ambient temperature. In view of the differences in track types and the complex and changeable working environment, railway spikes also show corresponding diversity in design and material selection.

Comparison of Electro-galvanized rail spikes and Hot dipped galvanized rail spikes
| Features |
Electro-galvanized rail spikes |
Hot dipped galvanized rail spikes |
| Before galvanization |
No need of clean. |
Must to clean grease and dirt. |
| Techniques |
Nails are galvanized with the help of an electrical current. |
Nails are submerged in molten zinc. |
| Layer thickness |
Thin, generally in 3 to 8 microns |
About ten times the thickness of electro galvanized layer, generally in 50 to 100 microns |
| Surface appearance |
Smooth and even,bright and shiny |
Dull, grainy, crystallized appearance |
| Corrosion resistance |
Unable to withstand continual exposure to corrosive materials such as saltwater. |
Much better than electro galvanized nails due to its thick zinc layer |
| Salt spray test performance |
Unable to withstand these types of surface abrasions in less than 10 hours. |
The salt spray test of hot dipped galvanized nails can be reached in about 30 hours. |
| Application |
Necessary for most residential purposes Not suitable to be used with acid materials, such as redwood, cedar, or treated lumber, etc. |
Necessary for outdoor exposure applications Enable to be used in bad environments such as acid, corrosive, humid circumstance. |
