China Dog Spike Suppliers - High Shear Strength Rail Fasteners for Wooden/Composite Sleepers Factory Compliant to EU EN 13481 & US AREMA
Basic Information
These dog spikes are dedicated fastening components for EU/US standard compliant rail fastening systems, mainly applied to fix tie plates to wooden or fiber-reinforced composite sleepers, preventing lateral and longitudinal displacement of plates and rails under dynamic train loads.
🌍
Global Standards
Conforms to EU EN 13481-2 (Grade 4.6/5.6 high-carbon steel) and North American AREMA Chapter 5 requirements.
🏗️
Heavy-Haul Support
Supports 25t axle-load for regional rails and up to 40t axle-load for heavy-haul freight lines.
🛡️
Extreme Durability
Hot-dip galvanized or dacromet treatment; 1200+ hour neutral salt spray test; resists -40℃ to 70℃.
⚙️
High Strength
Minimum shear strength of 800MPa; passes 3 million dynamic load cycle tests without deformation.
For EU markets, standard diameters range from 16mm to 22mm. For North American markets, standard sizes include 5/8", 3/4" and 7/8" diameter rivets. Their unique hook-shaped head design closely clamps the edge of tie plates, eliminating loosening risks caused by long-term vibration. Custom sizes and head shapes are available for special project demands.
