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. 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.
EU Standard Compliance
- Conforms to EN 13481-2 specifications
- Made of Grade 4.6/5.6 high-carbon steel
- Standard diameters: 16mm to 22mm
- Suitable for 25t axle-load heavy-haul lines & regional commuter rails
- Unique hook-shaped head design prevents loosening from vibration
North American Compliance
- Follows AREMA Chapter 5 requirements
- Standard sizes: 5/8", 3/4", and 7/8" diameters
- Perfect match with AREMA standard tie plates
- Supports up to 40t axle-load heavy-haul freight lines
- Engineered for high-impact load resistance
All products undergo hot-dip galvanized or dacromet anti-corrosion treatment, passing 1200+ hour neutral salt spray tests to adapt to extreme weather conditions. They pass 3 million dynamic load cycle tests without shear fracture or deformation, with minimum shear strength reaching 800MPa to resist strong impact from heavy cargo trains.
Frequently Asked Questions (FAQ)
What standards do these dog spikes comply with?
These dog spikes comply with EU standard EN 13481-2 specifications (using Grade 4.6/5.6 high-carbon steel) and North American AREMA Chapter 5 requirements.
What are the available sizes for different markets?
For EU markets, standard diameters range from 16mm to 22mm. For North American markets, standard sizes include 5/8", 3/4", and 7/8" diameters. Custom sizes and head shapes are also available upon request.
What axle-load capacities can these spikes support?
The EU standard spikes support 25t axle-load heavy-haul lines and regional commuter rails, while the North American AREMA standard spikes support heavy-haul freight lines with axle-loads up to 40t.
How do these dog spikes perform under extreme environmental conditions?
They feature hot-dip galvanized or dacromet anti-corrosion treatments, allowing them to pass a 1200+ hour neutral salt spray test and operate reliably in extreme temperatures ranging from -40℃ to 70℃.
What is the mechanical durability and shear strength of the spikes?
They pass 3 million dynamic load cycle tests without experiencing shear fracture or deformation, achieving a minimum shear strength of 800MPa to withstand heavy cargo train impacts.
