Products Description
The 18kg Chinese standard light rail is a type of light rail that complies with the Chinese railway rail standard, indicating a weight of 18 kilograms per meter of rail. This type of rail is suitable for railway lines with light loads and low traffic volume, and is widely used in industrial railways, mining railways, short distance railways, branch railways, and other occasions that require a balance between economy and load-bearing capacity.
Definition of 18kg Chinese Standard Light Rail
18kg: refers to a weight of 18 kilograms per meter of steel rail. This is a specification of lightweight steel rails, typically used in railway systems with lighter loads.
This type of rail complies with China's rail production and quality standards, which specify in detail the material, size, mechanical properties, testing methods, etc. of the rail.

Main characteristics of 18kg lightweight steel rails
Weight and size of steel rails:
The 18kg lightweight rail represents a weight of 18 kilograms per meter of track, which means it is lighter than traditional heavy-duty rails (such as 43kg, 50kg, 60kg, etc.) and suitable for railways carrying lighter loads. Its structure and size are compact compared to heavier steel rails, making it suitable for areas with lower transportation demands.
Material and chemical composition:
18kg lightweight steel rails are usually made of high-strength steel, and their chemical composition meets the relevant standards of China Railway. Common rail materials include Q235, Q345, etc., where Q refers to the yield strength of the steel (for example, Q235 represents a yield strength of 235 MPa). Carbon (C), manganese (Mn), silicon (Si), chromium (Cr) and other elements are usually added in the manufacturing process of steel rails to enhance their strength, toughness and wear resistance.
