Products Description
The maintenance cost of railroad tie nail is an important part of railway operating costs. The maintenance cost mainly includes the replacement cost, inspection cost and labor cost of the spikes. The service life of the spikes is affected by many factors such as material, environment and usage conditions, and the maintenance cost of different types of spikes varies significantly.
Although the initial purchase cost of ordinary steel spikes is low, due to their poor corrosion resistance and short service life, in the long run, the replacement frequency is high, resulting in increased maintenance costs; while stainless steel spikes and high-performance alloy steel spikes, although the purchase cost is higher, have a long service life and a long maintenance cycle, and the comprehensive maintenance cost is lower.
