Installation & Maintenance Perspective:
- Offers strong tensile and shear strength under heavy axle load conditions.
- Effectively suppresses rail movement caused by train vibration and impact.
- Maintains stable fastening performance without loosening over long service.
- Reduces stress concentration and lowers the risk of sudden breakage.
- Ensures consistent track gauge in high-speed and heavy-haul sections.
Maintenance & Operational Perspective
- Made of high-strength alloy steel with precise heat treatment process.
- Features high tensile strength and toughness to resist fracture.
- Surface coated for excellent corrosion and rust resistance outdoors.
- Maintains mechanical performance in humid and harsh environments.
- Extends service life and reduces frequent replacement frequency.
