Product Introduction
As a standardized railway product, GB heavy rails undergo multiple rigorous tests during the production process to ensure that the dimensional accuracy and straightness meet the standards; GB 75KG heavy rails further use special heat treatment processes to achieve a perfect combination of surface hardness and internal toughness, greatly extending the service life and reducing the cost of later maintenance.
75KG steel heavy rails are a type of heavy rails that play an important role in railway transportation. They are usually made of alloy steels such as U75V. The vanadium element in U75V forms fine dispersed carbonitrides to play a dispersion strengthening role, which can effectively improve the wear resistance and fatigue resistance of the rails. Heavy rail steel is produced by continuous casting of large square billets or die casting. To ensure quality, GNEE has strict requirements on the cleanliness of steel. The molten iron entering the furnace should be pre-treated, composite alloy deoxidation should be used, the molten steel should be vacuum refined, and full protection casting should be implemented. At the same time, through heat treatment processes such as full-length quenching, hard phase structures such as martensite and bainite can be formed on the surface of the rail head to improve the surface hardness and wear resistance.

Product Application
Product Packaging & Delivery
Heavy rails are fixed with steel belts or steel wires during transportation, and a fixed number of heavy rails form a bundle.
Protectors are used at the ends of the rails to protect the ends that are susceptible to wear.
GNEE RAIL attaches great importance to product quality and has established a strict quality control system. In the procurement process, we strictly screen and evaluate suppliers to ensure the quality of raw materials; in the production process, we work closely with cooperative manufacturers to supervise the production process and quality inspection to ensure that each batch of GB 75KG heavy rail products meets high standards; before shipment, we will also conduct strict finished product inspection to ensure that the products are not damaged during packaging, transportation and other links, and are delivered to customers in perfect condition.
