Products Description
There are many types of railroad spikes, the most common ones are ordinary railroad spikes, screw spikes, spring-clip railroad spikes, dog spikes, etc. Ordinary railroad spikes are usually used on wooden sleepers, with a flat head, and are fixed by directly driving them in during construction. Threaded railroad spikes have a spiral texture and are suitable for concrete sleepers. They need to be used in conjunction with plastic casings, and have stronger pull-out resistance and better stability. Spring-clip railroad spikes are used in elastic fastener systems, and are used in conjunction with accessories such as spring bars and gauge baffles. They are widely used in modern railways. Different types of railroad spikes have their own characteristics in design structure and mechanical properties. When using them, they need to be considered comprehensively based on factors such as railway grade, vehicle speed, load, and climatic conditions.

about Us
Strict quality inspection process, strict inspection before delivery
GNEE has established a complete quality inspection system, with quality inspection links at every step, from raw material storage, production process to finished product delivery. Each batch of road spikes must undergo size inspection, hardness test, tensile test and surface treatment adhesion test to ensure that they meet export standards in terms of physical properties, chemical properties and appearance quality. We also provide third-party test reports for customers to use during acceptance to enhance purchasing confidence.
