Alloy Steel Rail Screw Spike Fatigue Resistance For High Speed Railway W300-1 System

The SS36 screw spike is a professional high-strength threaded rail spike specially designed for high-speed railway W300-1 fastening systems. It is installed on concrete sleepers to fasten rail base plates, elastic fasteners and rail tracks, ensuring high stability, high precision and long-term safety for high-speed rail lines.

Manufactured from premium alloy steel and processed with integral forging and quenching & tempering heat treatment, our SS36 rail screw spikes deliver excellent tensile strength, fatigue resistance and vibration resistance. With heavy-duty anti-corrosion surface treatment, these spikes adapt to extreme outdoor temperatures, heavy vibration and harsh weather conditions, greatly reducing railway maintenance frequency and project costs.

All SS36 screw spikes are strictly produced according to TB/T railway industry standards. Standard sizes SS36-260, SS36-270, SS36-280 are in stock. Custom dimensions and surface treatments are available for global high-speed railway, heavy haul rail and urban transit projects.
