Product Introduction
GB heavy rails are produced in accordance with GB standards. Their mechanical properties have been strictly tested and they have sufficient toughness and hardness. They can remain stable in different climatic environments, ensuring that the railway tracks are always safe and reliable in long-term use, thus safeguarding railway transportation.
GB hot-rolled high-hardness heavy rail is an important steel product for railway tracks.
Features
High strength and high hardness: Through reasonable chemical composition design and hot rolling process, it has high strength and hardness, and can withstand the huge pressure, impact load and friction of the train. For example, the hardness and strength indicators of heavy rails made of U75V and other steel grades can meet the requirements of high-speed and heavy-load railways.
Good wear resistance: The high hardness characteristics make the heavy rail wear slowly under the long-term rolling of train wheels, which can effectively extend the service life of the rails and reduce the maintenance and replacement frequency.
Good toughness: While having high hardness and high strength, it also maintains a certain toughness, which can prevent brittle fracture of the rails under different ambient temperatures and complex stress conditions, and ensure the safety of railway operation.
Hot rolling: The heated steel billet is fed into the rolling mill for multiple rolling passes. During the hot rolling process, the rolling temperature, speed, reduction and other parameters are precisely controlled to make the rails obtain the specified size, shape and straightness, while improving the internal structure of the steel and improving its strength, hardness and toughness.

Product Application
Product Packaging & Delivery
The anti-rust packaging process is crucial in the foreign trade transportation of GB heavy rails. In export operations, we use a proven and mature anti-rust solution: first, evenly apply special anti-rust oil on the clean rail surface to form a basic protective layer; then use high-quality anti-rust paper to wrap each rail, paying special attention to the complete coverage of the easily corroded parts such as the rail head and rail bottom; finally, use anti-rust canvas to bundle the entire rail.
GNEE RAIL has been deeply involved in the global heavy industry for decades, and has always taken "quality creates the future" as its core concept to create a world-class crane rail product system. We have an internationally leading fully automatic continuous casting and rolling production line and have established a global warehousing and logistics network. In the future, GNEE will continue to increase its investment in intelligent manufacturing and green production to provide global customers with smarter and more environmentally friendly industrial solutions.
