The rail spikes have to withstand the huge vertical loads from the trains as well as the dynamic forces and vibrations generated during operation. The material and design of the spikes need to ensure that they do not loosen during long-term use and can withstand repeated external forces.The spikes prevent the track from loosening due to vibration, temperature changes, etc. during long-term use. This is particularly important for ensuring the safety of the railway, because loose tracks may cause railway derailments or other accidents.
1.Q235 steel:
Q235 steel is a common low-carbon structural steel with good processability and weldability. It is suitable for most conventional railway construction and has good strength and durability. In order to improve corrosion resistance, Q235 steel road spikes are usually galvanized.
2.Alloy steel:
In order to improve the wear resistance and fatigue resistance of road spikes, some high-demand railway lines use alloy steel (such as Cr-Mo alloy steel, Cr-Ni alloy steel, etc.) to make road spikes. These materials have higher strength, hardness and corrosion resistance.
3.Galvanizing:
Because road spikes are exposed to the external environment and are often corroded by weather, humidity, rain and other factors, they are usually galvanized (hot-dip or electroplating). Galvanizing can improve the corrosion resistance of road spikes and extend their service life.
