What are the different types of steel rail?
Steel rail is a type of steel bar that has a long, rectangular cross-section in the shape of an I or U. It is used to install railway tracks, and tracks for specialized vehicles such as cranes, trolleys, and locomotives, etc.
Steel rails can be classified according to various criteria, such as weight, size, shape, material, standard, and application. Here are some of the most common and widely used types:
- Light steel rail: This type of steel has a weight of one meter less than or equal to 30 kg, often has an I shape, and is used to install temporary transportation tracks, tracks for specialized vehicles in factories, construction sites, mining areas, etc. Light steel rails typically have materials made from Q235 or 55Q steel, with lengths from 6 to 12 m. Some typical types of light steel rails are P11, P15, P18, P22, P24, P30, etc.
| Classification | Height(mm) | Head (mm) | Bottom (mm) | Thick(mm) | Weight (kg/m) | |
| Light Rail | 8 KG/M | 65 | 25 | 54 | 7 | 8.42 |
| 9 KG/M | 63.5 | 32.1 | 63.5 | 5.9 | 8.94 | |
| 12 KG/M | 69.85 | 38.1 | 69.85 | 7.54 | 12.2 | |
| 15 KG/M | 79.37 | 42.86 | 79.37 | 8.33 | 15.2 | |
| 18 KG/M | 80 | 40 | 80 | 10 | 18.06 | |
| 22 KG/M | 93.66 | 50.8 | 93.66 | 10.72 | 22.3 | |
| 24 KG/M | 107 | 51 | 90 | 10.9 | 24.46 | |
| 30 KG/M | 107.95 | 60.33 | 107.95 | 12.3 | 30.1 | |
- Heavy steel rail: This type of steel has a weight of one meter greater than 30 kg, often has a U shape, and is used to install railway tracks, main tracks, curved tracks, tunnels, or to make tracks for tower cranes, gantry cranes, etc. Heavy steel rails typically have materials made from U71Mn or 50Mn steel, with lengths from 12.5 to 25 m. Some typical types of heavy steel rails are P38, P43, P50, etc.
| Classification | Height(mm) | Head (mm) | Bottom (mm) | Thick(mm) | Weight (kg/m) | |
| Heavy Rail | 38 KG/M | 134 | 68 | 114 | 13 | 38.733 |
| 43 KG/M | 140 | 70 | 114 | 14.5 | 44.653 | |
| 45 KG/M | 145 | 67 | 126 | 14.5 | 45.546 | |
| 50 KG/M | 152 | 70 | 132 | 15.5 | 51.514 | |
| 60 KG/M | 176 | 73 | 150 | 16.5 | 60.64 | |
- Crane rail: This type has a square shape and is used to make tracks for factory cranes, gate cranes, and cranes, etc. Crane rails are typically made from U71Mn steel, with lengths that vary depending on the needs. Some typical types of crane rail are QU70, QU80, QU100, QU120, etc.
| Classification | Height(mm) | Head (mm) | Bottom (mm) | Thick(mm) | Weight (kg/m) | |
| Crane Rail | QU 70 | 120 | 70 | 120 | 28 | 52.8 |
| QU 80 | 130 | 80 | 130 | 32 | 63.69 | |
| QU 100 | 150 | 100 | 150 | 38 | 88.96 | |
| QU 120 | 170 | 120 | 170 | 44 | 118.1 | |
Rail Fish Plate for Steel Rail
Type of rail joint
The type of joint can be divided into suspension type and bearing type according to the position of the sleeper.
- Suspended
With this connection method, the joint sleeper spacing can be reduced to enhance the joint's anti-buckling ability. The advantage of this connection is that the elasticity is better.
- Single-bearing pad type
When using a single bearing pad, the sleeper loses stability due to the unevenness of the sleeper.
- Double-bearing pad type
When using the double-bearing pad, the bearing joint of the fishplate is lightly stressed. As the sleeper supports the rail head, the winding at the joint is small.
