GB 50kg 60kg 75kg Heavy Rail

GB 50kg, 60kg, and 75kg heavy rails are the primary steel rail profiles used in Chinese mainline railways, high-speed passenger lines, and heavy-haul freight corridors. As reliable GB rail for rail construction, these products are manufactured to GB/T 2585-2021 "Hot-rolled steel rails for railway" and designed to withstand the extreme loads, high speeds, and continuous cycles of modern railway operations.

Made from premium U71Mn high-manganese steel, GNEE's GB heavy rails deliver exceptional strength, wear resistance, and fatigue life. The 60kg rail is the most widely used profile for high-speed and mixed-traffic lines, while the 75kg rail is specifically engineered for ultra-heavy-haul applications such as the Datong-Qinhuangdao coal corridor, where annual tonnage exceeds 400 million tonnes .

Comparison of U71Mn with other materials：

GB, UIC, and AREMA are major international steel rail standards. AREMA (USA) uses a yard-pound system (e.g., 115RE, 136RE) for North American heavy-haul. UIC (International/Europe, e.g., 54E1, 60E1) is metric, focusing on high-speed and general, and is common globally. GB (China) adheres to Chinese national standards, focusing on high-load and complex conditions.

GB 60kg vs UIC 60 vs AREMA 115RE:

GB 60kg, UIC 60, and AREMA 115RE are heavy-duty rail standards used for mainlines, but differ in weight, profile, and regional application. GB 60kg (60.64kg/m) and UIC 60 (60.21kg/m) are European/International profiles for high-speed/heavy-haul, while AREMA 115RE (~57kg/m) is a US standard for, typically, lighter traffic than 132RE.

• GB 60kg: Primarily used in China (GB2585-2007/GB/T 33948). It has a cross-sectional area of 7725 mm² and a mass of 60.64 kg/m.

• UIC 60 (60E1): Follows EN 13674-1/UIC860 standards. It is widely used in Europe and internationally, with a mass of 60.21 kg/m and a head width of 74.3 mm.

• AREMA 115RE: Defined by the American Railway Engineering and Maintenance-of-Way Association. It weighs approximately 115 lbs/yd (57 kg/m), making it lighter than the 60kg/m standards.

The packaging and shipping of steel rails are strictly implemented in accordance with international transportation standards and product protection requirements to ensure that the rails are intact and free from damage during long-distance transportation and loading/unloading.

For packaging, steel rails are first bundled with high-strength galvanized steel straps, with anti-collision rubber pads placed at the contact points to prevent scratches and deformation caused by friction between rails. Each bundle is labeled with clear marks, including steel grade, rail model, length, weight, and batch number, for easy identification and inspection.

The packaging and shipping process strictly follows environmental protection requirements, and all packaging materials are recyclable. GNEE RAIL can also provide customized packaging and shipping solutions according to customer needs, such as special packaging for oversized or customized rails, to meet the diverse transportation needs of global customers.
