Product Introduction
The railway fastener system is a complete set of devices used to connect the railway track rails with the foundation under the rails, including spring bars, gauge baffles, anchor bolts and other components. According to different railway standards, it can be divided into national standards, European standards, American standards and other types. In cross-border railway projects, it can meet the track technical requirements of different countries and regions and achieve seamless connection of the track system; in the reconstruction of old railways, its strong compatibility can adapt to the original track structure, and by replacing and upgrading the fastener system, it can effectively improve the overall performance of the track, enhance the adaptability of the track to the operation of new trains, and achieve the improvement of railway transportation capacity at a lower cost.
The W3 Rail Fastener System is unique in its structural design. It is mainly composed of key components such as spring bars, gauge baffles, insulated gauge blocks, iron pads, rubber pads and bolts. As the core component, spring bars are usually made of high-quality spring steel, such as 50CrV and other alloy steel materials.

The special shape design of SKL3 Rail Track Fasteners System can effectively absorb the vibration energy generated by train operation while providing strong elastic buckle pressure.
The gauge baffle and insulated gauge block work together to accurately adjust and stabilize the gauge to ensure the position accuracy of the rail during operation. The gauge baffle has good pressure and impact resistance; the insulated gauge block can prevent current leakage and reduce friction and wear between components.
The iron pad plays a role in dispersing the pressure of the rail and enhancing the integrity of the track structure. It is mostly made of cast steel or steel plate stamping, and the surface is specially treated to improve corrosion resistance. Rubber pads are placed between the rails and the iron pads, playing the dual role of buffering, shock absorption and insulation. They are usually made of natural rubber or synthetic rubber and have good elasticity, aging resistance and insulation properties.

Product Packaging & Delivery
Make a metal turnover box with elastic straps inside. The two ends of the elastic straps are fixed on opposite sides of the box body. The tightness can be adjusted according to the height of the goods. Place large fasteners in the turnover box, tighten the elastic straps to fix them, and then fill the gap between the goods and the box body with wooden blocks. The box cover is connected by hinges, locked with a padlock, and wrapped with several layers of high-strength plastic film on the outside. It is suitable for transporting overweight and irregularly shaped fasteners.
