Engineered for industrial sidings, mining transport lines, and gantry crane runways, GlorySteelwork 50kg rail offers the ideal balance of load-bearing stability and cost-efficiency. This specification is the industry-standard profile for medium-capacity railway networks and overhead lifting systems.
Manufactured strictly to the GB/T 2585 national standard, the rail is forged from high-strength steel (such as U71Mn) to withstand high-frequency rolling and heavy impact. Its superior resistance to wear and deformation ensures long-term track smoothness while significantly reducing maintenance costs. GlorySteelwork provides fully compliant 50kg rail solutions with standard stock and custom-length options to match specific engineering requirements.
The table below shows the detailed dimensions of the 50kg rail, covering essential parameters such as rail height, head width, and web thickness. This provides a clear reference for track installation, rail fastening compatibility, and project planning.
| Type of Rail | Standard | Dimensions mm | Steel Grade | Mass M | |||
| Height | Base Width | Head Width | Web Thickness | kg/m | |||
| 50kg Rail | GB2585-2007 | 152 | 132 | 70 | 15.5 | U71Mn | 51.514 |
Rail Length Options：
The standard length of 50kg rail is 12.5 meters. Custom cutting is available to meet project needs, including straight and angled cuts.
The 50kg rail is manufactured to meet different application requirements. For industrial and crane rail systems, it follows the GB/T standard, while for railway track use, it complies with the TB/T standard. This ensures the rail can perform reliably across various operational scenarios.
The primary steel grade for 50kg rail is U71Mn, chosen for its excellent mechanical properties and chemical composition. These characteristics directly influence wear resistance, toughness, and fatigue strength. Detailed mechanical and chemical specifications are provided in the table below for accurate reference.
