Knowledge of light steel rails!

Light steel rails are used to lay railways. They must withstand the pressure, impact load and friction during train operation, and they must have sufficient strength and certain toughness. The quality requirements are strict. In addition to ensuring its chemical composition, it also requires inspection of mechanical properties, drop weight test and acid leaching low-power structure.

Standard rail lengths are 12.5m and 25m. Knowledge of railway rails: Knowledge of heavy rails: rails with a nominal weight of more than 30kg per meter. Train rails and crane rails are heavy rails.

Train rails: used for railway laying, to withstand the pressure, impact load and friction during train operation, sufficient strength and certain toughness are required. The quality requirements are strict. In addition to ensuring its chemical composition, it also requires inspection of mechanical properties, drop weight test and acid leaching low-power structure.

Crane rail: The crane rail has a low height, a large head width and a large waist thickness, and only requires inspection of chemical composition and tensile strength. Used for laying crane tracks and trolley tracks.
