Products Description
There are many types of railroad spikes, depending on the material, purpose and shape. Flat-headed railroad spikes are mostly used on ordinary tracks, while round-headed railroad spikes are suitable for high-speed railways and special tracks because they can better disperse the impact force from trains. U-shaped railroad spikes are often used on heavy-duty railways. Their special shape and material can withstand greater pressure. According to the different needs of the railway, choosing the right type of railroad spike can effectively improve the stability and safety of the track. Different types of railroad spikes are suitable for different environments and operating conditions to ensure the best performance of railway facilities.
