Dog spikes are a vital component in the railway industry used to secure rails to sleepers and maintain track stability. They are also known as railroad spikes, rail spikes, or coach screws and come in different types, sizes, and materials.
When selecting dog spikes, multiple factors must be considered to ensure optimal performance and service life. These factors include track dimensions and cross-section, axle load, and environmental conditions.
Track Dimensions and Cross-Section
Track dimensions and cross-section are critical factors when choosing dog spikes. These parameters determine the required type and size of spikes. GNEE RAIL offers various sizes of dog spikes and provides customization services for spike dimensions, materials, and surface treatments according to customer requirements.

Axle Load
Axle load refers to the weight borne by each axle of locomotives or trains. This is a key consideration in spike selection, as the spikes must withstand the weight of passing rail vehicles. GNEE RAIL manufactures spikes in strict compliance with AREMA, UIC, and other international standards, ensuring excellent wear resistance and load-bearing capacity.
Environmental Conditions
Environmental conditions represent another crucial factor in spike selection. Spikes are exposed to various conditions including extreme temperatures, moisture, and corrosive substances. The selected spike material must withstand these operational environments. GNEE RAIL primarily uses carbon steel, cast iron, and stainless steel for spike production. From material selection through manufacturing to final inspection, we implement stringent quality control standards to ensure our spikes deliver superior corrosion resistance and adaptability to diverse environments.
