Products Description
Tracks play a very important role in China's rail transportation and industrial production, including heavy rails, light rails, and crane rails. A rail weighing more than 30kg is called a heavy rail, while a rail weighing less than 30kg is called a light rail.
1, Basic parameters of 18kg/m light rail:
Model: 18kg light rail, rail height: 90mm, bottom width: 80mm, head width: 40mm, waist thickness: 10mm, theoretical weight: 18.06kg/m
2, 18kg steel rail material:
There are mainly 55Q and Q235B. The 55Q material has better wear resistance compared to hard points and is generally used in mining areas and other environments. If there are no special requirements, Q235B light rail is cheaper. The light rail follows the standard: GB11264.

3, Light Rail Usage:
Light rail is mainly used for laying temporary transportation lines and light locomotives in forest areas, mining areas, factories, and construction sites. The 18kg light rail can carry a weight of about 3-5 tons (depending on wheel pressure and span).
