Products Description
GB 50kg heavy rail is widely used in China's railway transportation, especially in ordinary railways and some heavier freight railways.
50kg/m: 50kg heavy rail weighs 50 kg per meter and is a type of heavy rail. It is heavier than light rail (such as 30kg, 38kg rail), has a stronger load-bearing capacity, and is suitable for carrying larger cargo loads and higher traffic volume.
Scope of application:
Ordinary railway: 50kg heavy rail is often used in China's ordinary railways, especially some trunk railways or secondary trunk railways, which can carry a certain load of cargo and passenger trains.
Freight railway: Suitable for freight railways that transport bulk materials (such as coal, ore, steel, etc.), especially in railway sections with high requirements for load-bearing capacity.
Light high-speed railway: 50kg heavy rail can also be used in some light high-speed railways or some lighter railway systems, but in general, high-speed railways will choose heavier rails, such as 60kg or higher rails.

Other Features
50kg heavy rails are usually made of high-strength alloy steel or carbon steel, and are heat treated (such as quenching, tempering, etc.) to improve the hardness, strength and wear resistance of the rails.
This type of rail can withstand large train loads and high traffic density, ensuring smooth train travel and a long service life.
The geometric dimensions of the 50kg heavy rail (rail head width, rail root width, rail height, etc.) meet China's national standards to ensure its stability and good load-bearing performance. The track design takes into account factors such as train wheel wear, track strength and stability.
The design of this rail balances strength, cost and construction difficulty, ensuring the economy of construction and maintenance while providing good performance.
