What are the dimensions of the S24 rail?
Under DIN 5901, the S24 steel rail profile has a standard height of 115 mm, base width of 90 mm, head width of 53 mm, and web thickness of 10 mm, with a theoretical linear mass of 24.43 kg/m and a cross-sectional area of 31.18 cm². As a light-section Vignole rail, S24 is commonly used in overhead crane runways, mining and industrial tracks, tunneling systems, and light-duty transport applications.
Standard Dimensions of DIN 5901 S24 Rail
The S24 rail cross-section features a 53 mm rail head, 10 mm web, and 90 mm base, with rounded transitions between the main profile sections.
- 53 mm Head Width: Determines the wheel-to-rail contact area and should be matched with the applicable wheel profile.
- 90 mm Base Width: Provides the rail's mounting footprint and determines compatibility with rail clips, fastening systems, and supporting structures.
- 115 mm Rail Height: Defines the overall profile height and contributes to the rail's vertical load-bearing capacity.
| Height: 115 mm | Base Width: 90 mm |
| Head Width: 53 mm | Web Thickness: 10 mm |
| Length: 6m-10m | Material: Q235/55Q |
| Weight: 24.4 kg/m | Standard: DIN 5901 |
S24 Steel Rail Sectional & Mechanical Properties
For crane tracks and industrial rail systems, cross-sectional area, moment of inertia (I), and section modulus (W) are key parameters for evaluating load-bearing and bending performance.

| Distance to Neutral Axis | e_b | 55.40 mm | 2.181 in |
| Distance to Neutral Axis | e_t | 59.60 mm | 2.346 in |
| Moment of Inertia | I_x | 574.00 cm⁴ | 13.79 in⁴ |
| Moment of Inertia | I_y | 91.00 cm⁴ | 2.19 in⁴ |
| Section Modulus (Bottom Base) | W_x (base) | 103.60 cm³ | 6.32 in³ |
| Section Modulus (Top Head) | W_x (head) | 96.30 cm³ | 5.88 in³ |
| Section Modulus (Transverse Axis) | W_y | 20.20 cm³ | 1.23 in³ |

Frequently Asked Questions About S24 Rail Dimensions
What is the weight per meter of an S24 rail?
A DIN 5901 S24 rail has a theoretical mass of 24.43 kg/m (16.42 lb/yd). Actual delivery weight may vary slightly according to manufacturing tolerances.
How does S24 rail compare with S20 and S30 rail?
S24 is a medium-size DIN 5901 light rail profile. Its main dimensions are 115 mm height, 90 mm base width, 53 mm head width, and 24.43 kg/m theoretical mass. S20 and S30 have different profile dimensions and weights, so selection should be based on wheel load, track design, and application requirements.
Can S24 rail be used for crane runways?
Yes. S24 rail can be used for light-duty crane runways, monorail systems, gantry transfer tracks, and other industrial applications, provided that the rail profile is suitable for the calculated wheel loads and support conditions.
What bolt holes are used for S24 fishplates?
Fishplate hole diameter and spacing depend on the joint-bar design and project requirements. GNEE RAIL can provide standard or customized drilled fishplates according to customer drawings and fastening specifications.
