Rail and transit fasteners are engineered for strength, vibration resistance, and long-term reliability under heavy loads and dynamic conditions. Materials commonly include carbon steel for general structural use and alloy steel for high-tensile performance in bolted rail joints and anchor systems. Stainless steel may be used for components exposed to coastal or underground environments.

For protective finishes, Hot-Dip Galvanizing (HDG) is widely used to combat corrosion from moisture, salt, and debris on rail lines. Other finishes such as zinc plating or mechanical galvanizing are also applied depending on location and performance needs. Where electrical conductivity or tamper resistance is required, black oxide or uncoated variants may be selected.

At TUHU, we supply finish options tailored to the demands of track installations, elevated guideways, tunnels, and rolling stock assembly.
