What are the detailed 20 kg/m rail specifications?

 

In the global railway market, the "20 kg/m rail" almost always refers to the DIN 5901 S20 rail profile. While its nominal weight is rounded for commercial convenience, its precise technical specifications are strictly governed by international standards to ensure compatibility with industrial wheels, gantry cranes, and mining transport systems.

 

 

• Standard Compliance: Manufactured according to the DIN 5901 standard, ensuring dimensional uniformity across global supply chains.

 

• Mass Accuracy: The exact S20 steel rail weight is 19.80 kg/m, not 20.00 kg/m. This distinction is critical for precise load-bearing calculations in structural engineering.

 

• Structural Design: The profile features a 100 mm height and a 7 mm web, providing high vertical rigidity (moment of inertia) while maintaining a lightweight footprint for manual installation.

 

• Versatile Application: Widely used in S20 light rail systems for warehouse automation, light-duty gantry cranes, and underground mining loops.

GNEE RAIL produces S20 light rails that strictly adhere to these technical benchmarks. Our production process utilizes high-precision rolling technology to maintain the critical "fishing" angles required for a secure S20 rail fishplate connection. By focusing on RAIL S20 MATERIAL STRENGTH and dimensional consistency, we provide reliable track components that meet the rigorous safety demands of modern industrial infrastructure.

 

What are the complete Specifications of S20 Rail?

 

The S20 rail dimensions are engineered to balance vertical strength with lateral stability. The 82 mm base width ensures the rail resists tilting under side-thrust forces, while the 100 mm height functions as a structural beam to bridge gaps between supports.

S14	80	70	38	9	14
S18	93	82	43	10	18.3
S20	100	82	44	10	19.8

What are the dimensional advantages of DIN S20 rail?

 

The DIN S20 rail, manufactured according to the DIN 5901 standard, is a 19.8 kg/m, hot-rolled steel profile designed for medium-duty industrial applications. Its primary dimensional advantages lie in its balance of structural strength for medium loads while maintaining a compact, easy-to-install profile for specialized applications.

 

Key dimensional advantages include:

 

• Optimal Medium-Duty Profile: Weighing 19.8 kg/m, the S20 provides significantly higher strength, stability, and load-bearing capacity than lighter profiles like S10 or S14, while remaining lighter than S30 rails.

 

• Standardized Geometry (DIN 5901): The rail adheres to precise DIN 5901 specifications, ensuring compatibility with standard industrial fasteners, clips, and fishplates, simplifying the design and assembly of rail systems.

 

 

• High-Stability Design: The profile features a flat-bottom design with precise dimensions that enhance structural stability under moderate loads, making it suitable for crane tracks, mining tracks, and factory transport.

 

• Optimal Compactness for Confined Spaces: Despite its strength, the S20 profile is optimized for restricted environments, such as factory interiors, narrow warehouses, and mining tunnels, where large, heavy-duty rails cannot fit.

 

• Customizable Lengths: S20 rails are typically produced in 6m, 8m, and 10m lengths, allowing for flexible layout designs with fewer joints in medium-sized, high-traffic areas.

 

FAQ

 

• Is 20 kg rail the same as S20 rail?

Yes, in the context of light rails, "20 kg rail" is the common commercial name for the DIN 5901 S20 rail, which has a precise weight of 19.80 kg/m.

 

• What is the standard length for S20 rail?

The most common factory lengths are 6 meters, 10 meters, and 12 meters. Custom lengths can be provided based on your specific S20 rail drawing and site layout.

 

• Can S20 rail be used for heavy freight?

No, the S20 is a light rail profile. Heavy freight requires much larger sections, such as the UIC60 (60E1) profile, which can handle axle loads exceeding 22 tons.

 

• Which material grade is better for a gantry crane?

55Q is the superior grade for crane tracks. Its higher carbon content ensures the RAIL S20 MATERIAL STRENGTH can handle the repetitive point-loads of crane wheels without excessive wear.

 

• Are S20 rails compatible with GB 22kg rails?

No. The GB 22kg rail has a height of 108 mm and a wider head. Joining them requires a custom transition joint to manage the 8 mm height difference.
