Products Description
38kg heavy steel rails are a type of rail suitable for high-load, high-frequency railway systems. They are widely used in freight railways, some high-speed railways, and busy long-distance passenger routes. Their high load-bearing capacity, durability, and stability make them ideal for heavy-duty railway transportation. Despite their relatively high weight and cost, 38kg rails are still essential infrastructure in high-intensity, high-frequency railway transportation.
38kg steel rails are particularly suitable for railway systems with heavy loads, and can withstand the transportation of heavy goods and reduce the deformation and wear of the tracks.In some high-speed railway systems, 38kg rails can withstand the dynamic pressure of high-speed trains and ensure the stability of the tracks.
38kg steel rails are suitable for busy railway lines that need to carry a large number of trains, especially freight railway systems.

Other Features
Application scenarios
1.Heavy-load railway system:
38kg rails are often used in railway systems that transport bulk goods, such as coal, ore, steel and other heavy materials. Its high load-bearing capacity can meet the needs of busy freight railways.
2.High-speed railway system:
Although heavier rails (such as 50kg or 60kg rails) may be used in some high-speed railway systems, 38kg rails can also provide sufficient support in some high-speed railway systems, especially in the initial construction or more economical lines.
