Products Description
Railway Dog spikes have a high fixed force, are easy to fasten, and have economic advantages. They are more suitable for wooden sleepers, and most traditional railroads which are part of light rails or railroads that need frequent maintenance and replacement. Because of their low costs, they are especially suitable for large-scale use.
Q235 Material Dog spikes usually adopt high-strength carbon steel or stainless steel materials, such as Q235 carbon steel, Q345B carbon steel, etc., to ensure high strength and durability.

Contour features of dog spike
Just like their name, cut track spikes have a special and cute appearance that looks like a dog's head. Their head shape usually has an off-center head and twin flanges. The heads'off-center design adds the contact area between the spike with railroads and sleepers to provide a more stable fasten effect and the head is always wide and flat, easy to hammer. Meanwhile, the twin flanges help to add holding power and stability. As for their shaft bottom, there is a cutting-edge design that helps to insert the sleepers or track slab, providing good penetration and fixation force.

Comparison of dog spikes and screw spikes
Surface
The screw spikes are the railroad spikes with the screw thread on the surface. But as to the dog spikes, it has a pointed penetrating head with a smooth suface.
Power
As to the holding power, the screw spikes can provide more than twice of the power than the dog spikes.
Cost
Because of the greater fixing power and the feature that can be combined with spring washers, the cost of manufacture of the screw spike is higher than the dog spikes or dog nails.

FAQ
1.Q: What materials are your railway spikes made of?
A: Our railway spikes are mainly made of high-strength stainless steel, alloy steel and cast iron. Stainless steel spikes have excellent corrosion resistance and are suitable for humid environments such as coastal areas; alloy steel spikes have high strength and good toughness and can withstand greater impact; cast iron spikes are cost-effective and suitable for general railway lines.
2.Q: What are the specifications of railway spikes?
A: The conventional specifications are 20mm - 30mm in diameter and 80mm - 150mm in length. Special specifications can be customized according to customer needs, including different head shapes (such as mushroom heads, flat bottom heads, etc.) and thread sizes.
3.Q: What is the load-bearing capacity of the spikes?
A: Our spikes have been strictly tested. The alloy steel spikes can bear a load of 30 - 50 tons, and the cast iron spikes can bear a load of 20 - 35 tons, which fully meet the load-bearing requirements of various types of railway transportation.
4.Q: How is the corrosion resistance of the spikes?
Answer: Stainless steel road spikes are made of 304 or 316 stainless steel, which have excellent acid and alkali resistance and salt spray corrosion resistance; the surface of alloy steel and cast iron road spikes is hot-dip galvanized or coated with special anti-corrosion coating, which can effectively extend the service life and can be used for more than 10 years in general environment.
