China Dog Spike Suppliers: High Shear Strength Rail Fasteners for EU EN 13481 & US AREMA Compliance - Factory Direct
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.
EU Standard Compliance
Conforms to EN 13481-2 specifications. Made of Grade 4.6/5.6 high-carbon steel with standard diameters (16mm to 22mm). Suitable for 25t axle-load heavy-haul lines and regional commuter rails. Features a unique hook-shaped head design to eliminate loosening risks.
AREMA Standard Compliance
Follows North American AREMA Chapter 5 requirements. Available in standard sizes of 5/8", 3/4", and 7/8" diameters. Matched with AREMA standard tie plates to support up to 40t axle-load heavy-haul freight lines.
High Performance & Strength
Passes 3 million dynamic load cycle tests without shear fracture or deformation. Minimum shear strength reaches 800MPa to resist strong impact from heavy cargo trains.
Extreme Weather Resistance
Hot-dip galvanized or dacromet anti-corrosion treated. Passes 1200+ hour neutral salt spray tests, adapting to extreme weather environments ranging from -40℃ to 70℃.
The rivets are fully compatible with mainstream AREMA tie plate systems and European traditional wooden sleeper fastening systems. Custom sizes and head shapes are available for special project demands.
Frequently Asked Questions
Q: What is the primary function of these dog spikes?
They are dedicated fastening components designed to secure tie plates to wooden or fiber-reinforced composite sleepers, effectively preventing lateral and longitudinal displacement of plates and rails under heavy train loads.
Q: Which international standards do these dog spikes comply with?
They comply with EU standards (EN 13481-2 specifications) for European markets and US standards (AREMA Chapter 5 requirements) for North American markets.
Q: What are the available sizes and material specifications?
For European systems, they are made from Grade 4.6/5.6 high-carbon steel with diameters of 16mm to 22mm. For North American systems, standard sizes include 5/8", 3/4", and 7/8" diameters.
Q: How do these spikes perform under heavy dynamic loads?
They can support up to 25t axle-loads on European lines and up to 40t axle-loads on North American freight lines. They successfully pass 3 million dynamic load cycle tests without deformation, offering a minimum shear strength of 800MPa.
Q: What anti-corrosion treatments are applied to these products?
All products undergo hot-dip galvanized or dacromet anti-corrosion treatments, enabling them to survive 1200+ hours in neutral salt spray tests and operate reliably in temperatures from -40℃ to 70℃.
Q: Are custom size and design options available?
Yes, while they are fully compatible with standard AREMA and European wooden sleeper fastening systems, custom sizes and head shapes can be produced to meet specific project requirements.
