FAQ
Q: What components are included in a complete rail fastening system?
A: Typically includes rail clips (e.g., SKL, Nabla), base plates, insulators, spikes/bolts, and shoulder pads – customizable per project.
Q: What's the maximum axle load supported?
A: Standard systems handle 25-35 tons, with reinforced designs up to 40+ tons for mining railways.
Q: What material are rail clips made of?
A: Spring steel (60Si2MnA/SUP9A), heat-treated to HRC 42-50 for fatigue resistance.
Q: Can fasteners withstand extreme temperatures?
A: Yes, tested for -50°C to +80°C (arctic/desert applications).
