75KG Heavy Rail
GB heavy rails, under the framework of national standards, have strict production specifications and quality requirements to ensure that each rail can meet the needs of railway construction; GB 75KG heavy rails have increased the rail's carrying capacity for train loads by increasing unit weight and optimizing manufacturing processes, effectively reducing the risk of track deformation.
75KG railway tunnel heavy rails play an important role in railway tunnel construction. The theoretical weight of 75KG per meter gives the rails excellent strength and rigidity, which can better bear the large axle weight and frequent loads of trains in tunnels, and adapt well to long-term, high-intensity transportation operations, reduce track deformation and damage, and ensure transportation safety.
In addition, the rail head width, rail bottom width and other dimensions of heavy rails are large, and the contact area with the sleepers and roadbed is large, which can better disperse the train load, improve the stability and smoothness of the track, reduce the vibration and noise during train operation, and help improve transportation efficiency and reduce equipment wear.
Advantages of 75KG heavy rail
In addition to being used in railway tunnels, the 75kg heavy rail can also be used in tunnels for heavy freight and high-volume trunk lines. Its core advantages include:
Superior load-bearing capacity, distributing the pressure of heavy-load trains and reducing the risk of deformation;
High wear and fatigue resistance, reducing wear and cracking, and extending service life;
Excellent welding and adaptability, ensuring track integrity and smoothness;
Ensuring environmental corrosion resistance, suitable for humid and dusty tunnel conditions;
Compliant with national standards and rigorous testing, meeting tunnel safety requirements.
Since its establishment in 2008, the company has been deeply involved in the field of foreign trade of steel rails. After years of market experience and development, it has accumulated rich industry experience and deep customer resources. We have established long-term and stable strategic partnerships with several large domestic steel manufacturing companies with advanced production processes. These partners have world-class steel production equipment and strict quality control systems, which can ensure that we can continuously provide U75V 75KG national standard steel rail products that meet or even exceed national standards, laying a solid foundation for the company's business development from the source.
