Products Description
Railroad rails are the main component of railway tracks. The cross-section of the rails adopts an I-shaped cross-section with good bending resistance, which consists of three parts: rail head, rail waist and rail bottom.
In order to enable the rails to better withstand forces from all sides and ensure the necessary strength conditions, the rails should be of sufficient height, and their heads and bottoms should have sufficient area and height, and the waist and bottom should not be too thin.
Among various types of railway rails, 60kg/m and 50kg/m rails are laid on the main trunk lines, and 43kg/m rails are generally laid on station lines and dedicated lines. For heavy-load railways and particularly busy sections of railways, 75kg/m rails are laid.
The following is a table of rail model parameters and specifications, which can provide some reference：
| weight (kg/m) | material | length (m) | |
| 50kg | 51.514 | 50Mn/U71Mn | 12m/12.5m |
| rail height (mm) | bottom width (mm) | head width (mm) | web thickness (mm) |
| 152 | 132 | 70 | 15.5 |
