GB Standard Steel Rail

GB rails can be divided into crane rails, heavy rails, and light rails according to the kilograms per square meter.

• The crane rail: GB standard crane rail is divided into four types: QU120, QU100, QU80, and QU70. The material is generally manganese steel. The single weight is QU120, up to 118kg/m.
• The heavy rails: According to the steel grades used, heavy rail can be classified 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 types of 38, 43, 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. GB2585-81 specifies the technical conditions of 38~50kg/m rail in China.
• The light rail: There are mainly different types such as 9, 12, 15, 22, 30kg/m. The light rail is also divided into two types: GB (GB) and Ministry (MAB Metallurgical Standard). The above refers to several models of GB. The models of YB are 8, 18, 24kg/m.

The type of rail is expressed in kilograms per meter of rail mass. The rails used on railways in China have 75kg/m, 60kg/m, 50kg/m, 43kg/m and 38kg/m.

Among the above types of rails, 60kg/m and 50kg/m rails are laid on the main railway line, and the station line and special line are generally laid with 43kg/m rail. For heavy-duty railways and particularly busy section railways, 75kg/m rails are laid. In addition, in order to meet the needs of structures such as ballasts, special bridges and seamless lines, China’s railways also use special sections (asymmetrical with the central axis) rails. Nowadays, more rails for short special sections are used, which are referred to as AT rails.
