China's steel rail is classified according to the approximate weight of kilograms per meter, which can be divided into light rail, heavy rail and lifting rail (crane rail).

Light rail: light rail steel is a kind of steel which is produced by the nominal weight less than or equal to 30kg/m steel rail. Our country mainly refers to the type of steel the production of 8kg/m ~ 30kg/m light rail (including the switch). There are 8, 12, 15, 18, 22, 24, 30kg/m, etc.

Main uses: sliding way of electric expansion door; The slipway of the brick factory cart; Transfer the slide of the workpiece cart; The slide of a mine car. It is mainly directed and load-bearing, which is used with the track wheel to support the weight and change the direction of the cart.

Heavy rail: rail and crane rail, which weigh more than 30kg per meter, are also heavy rail. Our country is mainly refers to the production of 38kg/m ~ 60kg/m light rail (including bifurcation) use of steel. There are four basic models: 38, 43, 50 and 60kg/m.The factory has steel, angang, baosteel and panzhihua.

Main uses: power plant coal conveying line, steel market driving, steel structure workshop inside the sky crane. Special rail for driving, crane and crane; And power plant coal feeder line. Special railway; It is also used in subway rail.

Lifting rails: also called crane rail; Namely crane rail, its height is low, the head is wide and waist thick dimension is bigger, only ask to examine chemical composition and tensile strength. Used for laying cranes and trolley tracks. The production plant has angang and panzhihua. Model: the crane rail is divided into QU70, QU80,QU100,QU120, and four kinds of materials. The material is generally manganese steel. The largest single weight is QU120, which can reach 118kg/m.

Main use: mainly used for heavy equipment hoisting, gantry crane special lifting rails.Large engineering, wharf reloading containers, etc, gantry crane special.
