Carbon Steel Rail Dog Spikes

The main function of railway spikes is to firmly fix the rails on the sleepers so that they can maintain the correct position and gauge when the train is running at high speed. The spikes not only resist the longitudinal and lateral impact forces brought by the train, but also withstand the stress caused by thermal expansion and contraction due to temperature changes.

Without suitable road spikes, the rails may be displaced, loosened or even derailed, posing a great risk to the operation of the train. Therefore, although the railway spikes seem simple, they are one of the important guarantees for the safe operation of the entire track system. Together with fasteners, pads and other components, it constitutes the fastening system of the railway track and is inseparable.

Surface treatment of railway spikes

The surface treatment of railway spikes is mainly to improve their corrosion resistance, extend their service life and enhance the bonding strength between them and the sleepers. Common surface treatment methods include the following:

1. Blackening (oxidation treatment)

2. Hot-dip galvanizing

3. Electrogalvanizing (cold galvanizing)

4. Painting (spray painting)

5. Dacromet coating
