Railway & Rail Infrastructure
TUHU supports railway fasteners used in rail infrastructure systems designed for structural integrity, load-bearing performance, and long-term durability in demanding rail environments. These systems rely on high-strength fastening components to ensure secure connections across track assemblies, rail joints, and supporting structures.
We supply a complete range of railway fastening components including track bolts, rail joint bolts (fish bolts), structural bolts, heavy hex nuts, and washers, ensuring reliable performance, precise fit, and efficient installation across railway and transit infrastructure projects.

Materials & Finishes for Railway Fastening Systems
Railway fasteners are typically manufactured from high-strength carbon steel or alloy steel, selected based on load requirements, vibration resistance, and long-term operational performance in rail environments.
To enhance corrosion resistance and durability, finishes such as hot-dip galvanizing (HDG), zinc coating, and black oxide are applied, ensuring reliable performance under outdoor exposure and heavy-duty service conditions.
