Dog spikes and screw spikes are two most common railroad spikes that GNEE RAIL manufactures,it is small part used to ensure the safety of railway fastening systems. Both spike functions by the equipped offset head, so as to work as a nail that secure and fasten rails on the rail sleeper.
For Railway Projects Requiring Stable Promotion, ScrewRail Spikes Are Far More Adaptable and Cost-Effective Than Dog-Head Rail Spikes.
From the perspective of product performance, GNEE RAIL screw rail spikes are made of high-strength alloy material, with long-term anti-corrosion treatment on the surface. they can form a firm connection with concrete sleepers, withstand the impact force caused by frequent vibrations of heavy-duty trains, and are not easy to loosen even after long-term use. In contrast, dog-head rail spikes are only fixed on wooden sleepers by physical friction-they not only have limited applicable scenarios but also tend to loosen due to the wear of wooden sleepers, leading to troublesome subsequent maintenance.

In terms of scenario coverage, screw rail spikes are the mainstream choice for modern railways. Whether it is high-speed railways, freight dedicated lines or urban rail transit, as long as concrete sleepers are used, they can be matched with GNEE RAIL rail screw spikes. Dog-head rail spikes, however, are only applicable to wooden sleeper tracks and difficult to meet the requirements in heavy-load and high-frequency operation scenarios.
GNEE RAIL can provide a full range of spiral rail spikes and complete supporting components, and can also make customized adjustments according to project needs, as well as provide professional installation guidance. Choosing the right screw rail spikes can greatly reduce subsequent maintenance costs-contact us to obtain an adaptation plan!
