GNEE RAIL is manufacturing and supplying a wide range of rail screw spikes for railways. Railroad spike, also known as railway spike, track spikes, are designed with high precision and processed under mature technologies, which has been tested for decades.

Dog spikes

Dog spike was first to be invented in 1832, its named for the two lugs on either side which looks like a dog head, it has similar dimensions to screw spike, with a flange with a radius dog spike can fix rail track straight to rail sleeper. While screw spike firstly showed up in 1860, and it became more popular than dog spike for its greater fixing power, even if the cost to manafacture screw spikes is higher than dog spike, the maintain cost of screw spike is lower. Generally speaking, Screw spike are mostly used in heavy rail applications, dog spike are used in light rail tracks.

Screw Spike

Screw spike is also called sleeper screw, rail screw, through specific requirements such as length, diameter, drive head and thread profiles, the railway screw spikes can be classified into four types, including the Ss series sleeper screw, the square-head screw spike, the hexagon screw spike, and the double-head screw spike.

Screw Spike Manufacturing Process

Manufacturing Process for screw spike: Raw Material→Wiredrawing→Rod Cutting→Head Forming→Edge Cutting→Thread Rolling→Heating Treatment→Surface Treatment→Final Inspection→Packing→Shipment

Railway spike material

Basically railroad spikes are made out of the following materials:　Q235 carbon steel, Q 345B carbon steel, Q345D carbon steel, 45# (GB standard) carbon steel, 40Cr steel, 35CrMoA steel and 20MnTiB.

The differences of the material that used for making railroad spikes:

Q235 carbon steel: it features in good plastic property, toughness and welding performance. It also has good cold pressing and bending. The Q235 carbon steel is always used for parts and welding structure application with average requirements.

45# carbon steel: it is the most used medium carbon steel. Good comprehensive mechanical properties. It is easy to crack in cold pressing. It is widely used for manufacturing moving parts with higher strength, such as gears, shafts, teeth, etc.

Q345 carbon steel: Good comprehensive mechanical properties, good processing performance with cold and hot pressing. Good corrosion resistance. It is typically used in the welding structural parts with high loading, such as ships, boilers, pressure vessel, crude oil tank, bridge, power plant equipments, crane, etc.

40Cr steel: after conditioning, it has good comprehensive mechanical properties, toughness in low temperature impact. Poor welding property, easy crack. It is one of the most used steel. You can find this material in gears, shafts, worm, sleeve, pin, rod, screw, bolt, valve, etc.

Customers can choose railroad spikes made out of the material that they need.
