Products Description
Railway spikes can be divided into many types according to their structure and installation method. The most common is the cut spike, which is characterized by a four-sided nail body and is installed in the wooden sleeper by hammering. It is suitable for general railway lines. The screw spike adopts a threaded structure and needs to be screwed into the sleeper with a wrench or special tools. It has stronger nail holding force and maintainability and is often used in heavy-duty railways.

The spring spike is made of elastic material, which adapts to the vibration environment of the track and helps to improve the smoothness of train operation. In addition, there are many variants such as U-shaped spikes and buckle spikes, each with its own specific application scenarios. For example, the mining area railway mostly uses U-shaped spikes with simple structure, while the high-cold area will use galvanized spiral spikes with stronger corrosion resistance. Choosing the right type of spike can not only extend the life of the track, but also improve the overall operational efficiency.
Products Description
Surface treatment of railway spikes
The surface treatment of railway spikes is mainly to improve their corrosion resistance, extend their service life and enhance the bonding strength between them and the sleepers. Common surface treatment methods include the following:
1. Blackening (oxidation treatment)
2. Hot-dip galvanizing
3. Electrogalvanizing (cold galvanizing)
4. Painting (spray painting)
5. Dacromet coating
about Us
Quality is the foundation of our survival and development. GNEE has an independent quality inspection department, which uses advanced testing equipment to conduct full-process quality control of raw materials, production processes and finished products. Every piece of railway equipment must pass strict performance tests and dimensional inspections before leaving the factory to ensure that it meets international standards. Because of this, our products have performed well in many international railway projects and have won unanimous praise from customers.
FAQ
Q: Does the installation of road spikes require special tools?
A: Embedded and anchored installations generally use conventional drilling and pouring tools; welding installations require professional welding equipment. We will explain the required tools and operating methods in detail in the installation guide.
Q: What should I do if there are quality problems with road spikes?
A: If you find quality problems, please contact us in time. We will respond within 24 hours and arrange professionals to communicate and deal with them. If it is confirmed that it is a product quality problem, we will provide free replacement or repair services.
Q: What is the specific anti-rust treatment of road spikes?
A: Alloy steel and cast iron road spikes are hot-dip galvanized, and the thickness of the galvanized layer is ≥80μm, which can effectively isolate air and moisture; in addition, anti-corrosion paint or Dacromet coating can be applied according to customer requirements to further enhance the anti-rust performance.
Q: What is the fatigue resistance of road spikes?
Answer: After fatigue tests simulating long-term railway operation, our spikes can still maintain good structural integrity and mechanical properties after withstanding more than one million cyclic loads, effectively reducing damage caused by fatigue.
