The QU70 is differerce with 70kg, it is very important to know the detail specification about them.

The sectional dimension of 70kg steel rail: rail height: 120mm, bottom width: 120mm, head width: 70mm, thickness: 28mm, theoretical weight: 52.8kg.

The material of 70kg steel rail: U71Mn.

The standard of 70kg steel rail: YB/T5055-93.

The length of 70kg steel rail: 12m/stick

QU70 is a kind of representing method of steel rail type, the rails are generally divided into the following types: 24kg/m, 43kg/m, 50kg/m, QU70, QU80, QU100, QU120, the expression of kg/m is equal to the theoretical weight, the expression numerical value of QU is different to theoretical weight, such as, the theoretiacl weight of QU70 steel rail is 52.8kg/m. So the 70kg steel rail is not the theoretical weight of 70kg/m, the number of QU70, QU80, QU100, QU120 is rail head width.

At present, the factory leaves out QU70, QU80, QU100 and QU120 crane rail without holes. If customers need, we can process.
