The Classification Of Rail

Chinese rails can be divided into crane rail, heavy steel rail and light steel rail in kilograms per square meter.

1. The crane rail is divided into four types: QU120, QU100, QU80, QU70. The material is generally manganese steel. The single weight is QU120 up to 118kg/m.

2. Heavy steel rail. According to the steel used, the steel can be divided into ordinary manganese-containing rails, copper-containing carbon steel rails, high-silicon copper-containing steel rails, copper rails, manganese rails, silicon rails, etc. There are three main types: 38kg, 43kg and 50kg. In addition, there are 45kg rails for a few lines, and 60kg rails are planned for use on lines with high traffic and high speed.

3. Light steel rail. There are mainly different rail types such as 9kg/m, 12kg/m, 15kg/m, 22kg/m, 30kg/m.

Each country in the world has its own standards for the production of rails, and the classification methods are also different.

Such as British standard: BS series (with 90A, 80A, 75A, 75R, 60A, etc.)

German standard: DIN series crane rails.

International railway union: UIC series.

American standard: ASCE series.

Japanese standard: JIS series.
