43kg Rail
The 43kg rail is a premium-grade solution engineered for high-load railway and industrial applications, compliant with GB2585-2021 national standards. Constructed from U71Mn high-manganese steel, it delivers exceptional tensile strength (≥880MPa) and wear resistance, making it ideal for main railway lines, heavy freight corridors, and industrial crane systems. With a weight of 44.653kg/m and robust dimensions (140mm height x 114mm base), this rail ensures reliable performance under continuous heavy traffic and harsh environmental conditions.
Every rail delivered with traceable quality assurance
