Get to Know More about Railway Fish Plate Standard

The standard rail length is 12.5m and 25m.

Steel Rail Classifications

The rail is divided into heavy rail and light rail by the number of kilograms per meter of approximate weight:

Heavy rail

According to the steel used, it can be divided into: common steel rails containing manganese, common steel rails containing copper, high silicon steel rails containing copper, copper rails, manganese rails and silicon rails. There are mainly three types: 38kg, 43kg and 50kg. In addition, there are also 45kg rail tracks for some road lines, which have been planned to use 60kg tracks for high speed rail routes.

Light rail

There are 9, 12, 15, 22, 30 and other types of rail track.

Manufacture And Application of Railway fish plates

The rail is made of carbon - stabilized steel, which is smelted by open - hearth and oxygen converter. Its purpose is to bear the running pressure and impact load of locomotive and vehicle.

Manufacturers And Importing Countries

The rail used in China is mainly produced by some domestic steel mills, such as Anshan steel, Wuhan steel, etc. In addition, due to the large amount of consumption, it is still necessary to import some of the physical and chemical properties required by China's technical standards and the steel rails and accessories determined by relevant foreign standards. The importing countries are Japan, Germany, France, Britain, Russia, Australia and so on.

Dimensions of Railway Fish Plate

The length of the rail and other geometric dimensions and tolerances shall be specified by the relevant standards of light and heavy rails in GB Standard.

Appearance And Quality of Railway Fish Plates

The rolled rail shall be straight without significant bending and torsion.The local bending and torsion of light and heavy rails and the amount of deformation and the inclination of rail end surfaces shall not exceed the standards.
The surface of the steel rail shall be clean and smooth, without cracks, scars and scratches. The end face shall not have shrinkage marks or interlayer, etc. The degree to which defects and geometric quantities are allowed to exist on the integral surface of light and heavy rail shall not exceed the standards.
Our main products are: various types of light, heavy rail high manganese steel casting single open, compound crossover, crossover line, diamond, symmetry and other kinds of turnout. According to the rail type, there are: 8kg/m, 12kg/m, 15kg/m, 18kg/m, 22kg/m, 24kg/m, 30kg/m, 38kg/m, 43kg/m, 50kg/m, and 60kg/m rail crossings.
