High Quality Railway Spikes On Sale

Product Classification

There are many types of railway spikes, but the most common classification is spiral spikes and dog spikes.

Dog spikes

Dog spikes have an L-shaped head that looks like a dog’s head and a square shank with the head angled to fit the top surface of the track foundation. Typically, spikes are offered in various sizes to meet different requirements for spike penetration length. For smaller track sections, 5/8″*6″ and 9/16″*5-1/2″ are the two most common dog spikes, and they are usually packaged in 200 lbs or less buckets or 50 lbs buckets.

Railway Screw

Threads are a shape with uniform screw protrusions on the cross-section of a solid outer or inner surface. They can be used in conjunction with plastic ferrules and cast into concrete sleepers/sleepers. Railway screw spikes can vary in thread profile, length, diameter, and drive head according to different international standards and specific geographical requirements.

Square head screw spike

The square head screw spike has a square design. Compared with the round head of the traditional spike, the square head design provides a larger contact surface area, which helps to improve the contact surface between the spike and the rail and increase the fixing stability.

Double head screw spike

The double head screw spike is a specially designed spike with two heads, where the larger head is used to fix on wooden or concrete sleepers, and the smaller head is used to connect with the rails.
This design makes installation more convenient and efficient, while improving the stability and firmness of the spike. Double head spiral spikes are usually used in conjunction with the Nabla clip system, which is particularly popular in Africa.

Product Description

Railway spikes, also known as railroad spikes or spikes in railway track, are an essential part of railway infrastructure. They are used to secure rails to the sleepers below, which are fixed to the ballast bed. Without these spikes, the rails would move and become unstable, leading to accidents and derailments.

In railway construction, spikes are driven into wooden or concrete sleepers on the rail base and fixed to the ground by hammering or mechanical pressure. The use of spikes can prevent lateral or horizontal movement of the rails, better meet the technical requirements and installation requirements of the elastic fastener system, while improving the safety factor and ensuring the convenience and smoothness of railway transportation.

Gnee produces train track spikes of various shapes and different uses, such as dog spikes, screw spikes, SS series spikes, square-head spiral spikes, hexagonal spiral spikes, double-head spiral spikes, etc.

Production process of railroad spikes

The production process of road spikes in Gnee factory generally includes the following steps:

Raw material preparation: The main raw material of road spikes is high-quality carbon steel, which meets the relevant national standards and quality requirements.
Heating and forging: First, the steel is heated to an appropriate temperature, and then it is molded into the initial shape of the road spike through a forging process.
Head forming: The initial shape of the spike rod is placed in the forming mold, and one end of the spike rod is formed into the shape of the road spike head by stamping or forging.
Trimming and shaping: The formed road spikes are trimmed, including trimming irregular parts, removing rust, etc., to ensure that the surface of the road spikes is smooth and the quality is good.
Heat treatment: Heat treatment is performed on the road spikes to improve their hardness and strength to ensure that the road spikes have good performance during use.
Surface treatment: Through surface treatment methods such as galvanizing, the corrosion resistance of the road spikes is increased and their service life is extended.
Quality inspection: Strict quality inspection is carried out on the produced road spikes, including the detection of indicators such as appearance quality, dimensional deviation, hardness, etc., to ensure that the road spikes meet the relevant standard requirements.
Packaging and warehousing: Finally, qualified road spikes are packaged, usually in boxes or bundles, and then stored in warehouses waiting for sale or use.

Dog Spikes VS. Screw Spikes

The main difference between railway dog spikes and screws:
In terms of materials, both dog spikes and screw spikes are usually made of carbon steel. But their styles and uses are different;

dog spikes vs screw spikes

Appearance:

Dog spikes
Used to fix wooden sleepers and T-shaped railway tracks to sleepers. Dog spikes have a pointed head and a square shank, and the underside of the head is tilted to fit the top of the rail base. They are also called cutting spikes.

Screw spikes
Used to hold down the base plate that connects the rails to the sleepers and prevent vertical and lateral movement between them. Screw spikes have a threaded rod and a flat head. They are also called driving spikes.

Securing sleepers:

Dog spikes are only used for wooden sleepers, while railway screw spikes are used for concrete sleepers. With the increasing application of concrete sleepers in railway construction, screw spikes are becoming more and more popular and in greater demand.

Pullout resistance:

The pullout resistance of spiral spikes is 0.5-1.0 times that of dog spikes, but the thrust resistance is 50% smaller.

Scope of use:

Rail screw spikes are often used in areas with high traffic, movement, and vibration, as their threads help prevent them from loosening. In addition, spiral spikes are often used with plastic sleeves.

Inserting method:

Dog spikes are usually hammered into wooden sleepers by hand. Screw spikes are usually fixed to concrete sleepers by anchoring technology.

Cost:

Railway screw can provide more than twice the fixing force of dog spikes. Due to the greater power and the characteristics of being combined with spring washers, the process of manufacturing screw spikes is more complicated than dog spikes, so the cost is higher than dog spikes.

Therefore, during the procurement process, the appropriate spikes should be purchased according to the actual needs;
