Product Introduction
GB light rail is a type of railway track material manufactured in accordance with China's national standard (GB), which is specially used for railway transportation scenarios with medium and low traffic volume. Its weight per meter is between 8-30kg, covering 8 specifications such as 8kg, 9kg, and 12kg. It is mainly made of carbon steel or low alloy steel and is made by hot rolling process.
From a functional point of view, GB light rail can withstand the load of small and medium-sized trains or transport vehicles, and is suitable for urban light rail auxiliary lines, local railway branches, factory and mine enterprise dedicated lines, scenic sightseeing railways and other lines. In the entire railway track system, GB light rail complements heavy rails, fills the demand gap of low-volume and low-cost track construction, and provides basic rail transportation services for specific areas and scenarios at a lower cost and maintenance cost. It is an indispensable and important part of railway infrastructure construction.
Q235B 15KG railway light steel belongs to the category of light rail, and "Q235B" represents its material characteristics.
Mechanical properties: Q235B 15KG railway light steel has a certain strength and can withstand vehicle loads and related forces during railway operation. Its good plasticity and toughness make it less likely to suffer brittle fracture when facing complex stress conditions, such as small-scale deformation and vibration impact of the track, thus ensuring the safety of railway operation.
Processing performance: Due to the characteristics of chemical composition, the steel has strong machinability. It can be made into the specified light rail shape through hot rolling and other processes. During the construction and installation process, it is easy to cut, drill, weld and other operations, which is convenient for track laying and connection according to actual engineering needs, reducing construction difficulty and improving construction efficiency.
