38kg Rail
The 38kg rail is a premium solution designed for extreme heavy-duty applications, engineered to meet the rigorous GB2585-2021 national standard. Constructed from U71Mn high-manganese steel, this rail offers exceptional tensile strength (≥880MPa) and wear resistance, making it ideal for high-load environments such as large mine roadways, industrial crane systems, and heavy-duty railway lines. With a weight of 38.73kg/m and robust dimensions (134mm height x 114mm base), it ensures reliable performance under continuous heavy traffic and harsh industrial conditions.
Every rail delivered with traceable quality assurance
