Hot Dip Galvanized Railway Fasteners
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.
Custom Hot Dip Galvanized Round & Square U-Bolts
Sea transit poses two main risks to HDG fasteners: white rust from container rain and thread damage from vibration & impact. Proper packaging uses sealed PE bags, desiccants and dry pallets against moisture. Weight limits, heavy-duty cartons and firm securing prevent thread damage. Standardized packing fully protects goods during shipping.
