china coal 0001 Introduction of 43kg Railway Heavy Steel Rail Normally, steel rail is devide into light rail heavy rail and crane rail . The nominal weight of light rails is 30kg or less. Our light rails are available in various specs. and are mainly used for laying temporary hauling tracks in forested areas, factories, mines, and construction areas. Heavy steel rail is the main component of railroad track.Heavy steel rail's function is to lead the locomotive wheels go forward, bear huge pressure of the wheels, and transfer to the sleeper. Heavy steel rail must provide wheels with continuous and smooth and the least resistance of the rolling surface. Besides all kinds of international standard steel and iron products, we also can develop and manufacture various non-standard products. Here are the types of steel rails: It is including light rails, heavy rails, crane rails and rail fittings. 1)Light rails: 9kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg Steel grade: 55Q / Q235 Length: 6m~12m Executive standard: refer to GB11264-89?¦ 2)Heavy rails: 38kg, 43kg, 50kg, 60kg Steel grade: U71Mn / 50Mn and so on Length: 12.5m Executive standard: refer to GB2585-81/QB In order to ensure better quality, our steel rails have to undergo many tests, including chemical composition test, tensile strength test, hardness test and the drop weight test. According to clients' demands, we can provid various specification rails with different materail/steel grade .
