As the core load-bearing component of railway tracks, the material properties and dimensional accuracy of rails directly determine line capacity, safety, and stability. The exported CR73 rails are made from the industry-recognized, high-quality, wear-resistant material U71Mn. This material offers high strength, high toughness, excellent fatigue resistance, and wear performance, precisely adapting to Vietnam's complex geological and climatic conditions. It is suitable for widespread use in the construction of conventional railways and suburban rail lines.
JIS Standard CR73 Rail Material Strength
The order explicitly adopts the standard specification of 10 meters per rail, with a batch configuration of 10 rails, fully meeting the engineering construction needs of the Vietnamese client. This will provide core material support for the efficient construction of local rail lines.
To ensure the smooth progress of the order, GNEE RAIL formed a dedicated task force, strictly controlling the process from the raw material procurement stage by selecting U71Mn steel billets that comply with international standards. During production, relying on advanced rolling processes and intelligent inspection equipment, key indicators such as the rail's dimensional accuracy, surface quality, and mechanical properties were monitored in real-time throughout the entire process. Multiple rounds of specialized inspections were conducted cumulatively, ensuring that every single rail complies with international rail transit material standards and the client's customized requirements.
Taking this export as an opportunity, GNEE RAIL will continue to focus on the research, development, and manufacturing of core rail transit equipment, continuously enhance the international adaptability of its products, deepen cooperation and exchange with clients in Southeast Asia, and contribute China's manufacturing expertise to promoting local rail transit infrastructure development and fostering regional connectivity.
As a professional supplier of mining rail, GNEE RAIL not only provides high-quality light steel rails but also a full range of compatible installation accessories, ensuring safe and efficient operation of the entire rail system. All accessories undergo strict quality control to perfectly match rails, enabling "one-stop procurement + worry-free installation."
- Fish Plates(Rail Joint Bar) and Bolts: Fish plates serve to connect steel rails and distribute loads, ensuring track stability. Hole patterns can match standard CR73 profiles or be customized. High-strength bolts (grade 8.8 or 10.9) ensure tight connection.
- Rail Clips: GNEE RAIL can provide rail clip models suitable for CR73 rails under different construction requirements: Wjk-model, ZYM-Model, KPO-3 / KPO-6, and weldable rail clips.
- Rubber Pads: Rubber baseplates are used beneath the rails to absorb vibration and shock, helping reduce noise and extend track life. GNEE RAIL offer rubber matting for CR73 rail bottoms, with a regular thickness of 510mm, made of highly elastic black natural rubber material, which can be customised to the size of the rail bottom.
- Rail Soleplates: The base plate, also known as the sole plate, is an optional but important accessory used beneath the rail to provide enhanced stability and load distribution. They are especially useful when the rail is installed on concrete floors or steel beams, helping to reduce vibration, protect the substructure, and extend the life of both the rail and the foundation. Custom drilling and surface treatments are available to meet specific installation requirements. When combined with rail clips or anchor bolts, base plates offer a complete and reliable track fastening solution.
- Alumothermic Welding kits for Rails: GNEE RAIL offers a full set of alumothermic welding equipment for crane rail track installation. Our solution uses an aluminum – iron oxide exothermic reaction to form high – strength, fatigue – resistant joints. With no need for complex power setups, it enables rapid on – site installation, making it a preferred choice for heavy – duty crane rails.
- Anchor Bolts & Embedded Parts: Anchor bolts and embedded components are essential for securing the rail system to concrete foundations. Available as expansion bolts, chemical anchors, or pre-embedded steel channels for heavy-duty crane track installations.
