Custom HDG fasteners with strong anti-corrosion, tailored for various heavy engineering projects.
Railway fastening systems are vital safety components that secure rails to sleepers and connect rail sections, enduring strong vibrations while maintaining standard track gauge. Exposed to harsh outdoor conditions, fasteners face severe corrosion. Our hot dip galvanized (HDG) fasteners with a zinc coating over 40μm provide durable anti-rust performance and reduce maintenance work. Hotop supplies standard-compliant HDG rail fasteners, including bolts, screws, and matching accessories per UIC, AREMA, DIN, and GB standards.
