Product Introduction
GB heavy rails are mainly used for laying track lines that bear train loads. They are mainly made of high-carbon steel with a carbon content of 0.6% - 0.8% or alloy steel with micro-alloying elements such as niobium, vanadium, and titanium. The comprehensive performance of the steel is improved through special smelting processes. The rail production adopts advanced online heat treatment technology to induction harden the rail head to form a wear-resistant surface with a hardened layer depth of 8 - 12mm and a hardness of 40 - 45HRC. Throughout the production process, the size and internal quality of the rails are monitored in real time through automated testing equipment to ensure that each heavy rail meets the requirements of high strength, high wear resistance, and good fatigue resistance, and can serve stably in the railway track system for a long time in various complex environments.
75KG heavy rail steel for coal mines is a kind of steel specially used for heavy-load transportation tracks in coal mines or on the ground. The tensile strength of 75KG heavy rail steel for coal mines is usually not less than 900MPa, and the yield strength is above 500MPa. It can withstand frequent heavy-load impacts in coal mine transportation and reduce track deformation and damage. By optimizing the alloy composition and heat treatment process, its surface hardness can reach HB300-HB350, and its wear resistance is 20%-30% higher than that of ordinary steel rails. It can adapt to the complex transportation environment in coal mines and extend the service life of the track.

Product Packaging & Delivery
In response to the high-efficiency operation requirements of heavy rail packaging, we use pre-formed bundling frames. The steel strips are pre-bent into a U-shaped frame that fits the size of the heavy rails. During on-site assembly, you only need to embed the rails into the frame and lock the buckles, which greatly shortens the bundling time. The anti-rust treatment uses nano-silicon dioxide composite anti-rust oil, which uses the filling effect of nanoparticles to form an ultra-dense protective film on the surface of the rails, and then covers it with a degradable bio-based plastic film to implement the concept of green packaging.
GNEE RAIL has been focusing on GB heavy rail foreign trade for more than ten years, and has been deeply involved in the international market with the concept of "quality as the root, service as the basis". We have established a strict supplier evaluation system and conduct annual assessments on the production process, quality management, and environmental protection level of the cooperative steel mills to ensure reliable quality at the source. GNEE has a professional technical team that can provide customers with value-added services such as heavy rail selection and track laying technical consultation. In terms of logistics and distribution, our business personnel can flexibly choose full container, LCL or bulk carrier transportation methods according to the characteristics of the goods and delivery period.
