Rail Spike is a kind of fasteners which is used to connect steel rail and sleeper or base plates and sleeper. The rail spikes are roughly chisel-shaped with a flat-edged point. The main function of the rail spike is to keep the rail in gauge. Rail dog spikes provide a strong, simple and inexpensive solution to securing rail track. Our products can also be customized according to clients' requirement.

A railway spike or a railroad spike is a large nail with an offset head that can hold rails and baseplate firmly to the tie (sleeper). It is a small component of the railway fastening system. On track material market, railway spikes have various types according to the structure and way of installation. The dog spikes and the screw spikes are two typical types. As to the making process, two ways are adopted. One is producing railway spikes by manual work. The other is a series of process such as forging, heat treatment and threading through machines.

Railroad spike functions:

Usually, railroad spikes have great durability and corrosion resistance that stand for long train operations and environmental effects. Their special design plays a supporting role in evenly spreading pressure caused by trains to rairoad sleepers and ground and reducing the rails and the support structures damage caused by pressure.
Above all, through nailed-in sleepers, railroad spikes can fix the orbit position and ensure the railway systems' stability and safety, preventing rail shifts and traffic accidents.

Quality control of railroad spike

When purchasing raw materials, we closely check production batch number, chemical composition, mechanical properties, and other detection indicators.

We stipulate our quality inspector adopt the methods of the combination of sample sampling, and batch testing and examine the material quality certificate of the raw material to ensure the product quality.

We will make corresponding chemical tests and physical tests according to the different product requirements, If the product is unqualified, we will deny it to reception until we are satisfied.

What's more, we usually organize quality control and coordination meetings to make technical acid and guidance, aiming at sending the certified products to our customs' hands.
