Are 20 kg/m rail specifications identical to S20 Rail?

Are 20 kg/m rail specifications identical to S20 Rail?

 

Yes, the 20 kg/m rail (often referred to simply as 20kg light rail) and the S20 rail are generally considered identical in terms of their core functional specifications, as the "S20" classification specifically denotes a rail with a nominal mass of approximately 19.8 to 20 kg/m.

 

Both are typically manufactured according to the DIN 5901 European standard for light steel rails.

 

Key Specifications of S20 Rail (DIN 5901)

 

S20 rail (DIN 5901) is a European standard light-duty steel rail primarily used for industrial, mining, and crane tracks, weighing 19.80 kg/m. It features a 100mm height, 82mm base width, and 44mm head width, commonly produced in 6–12m lengths using Q235B or 55Q steel for durable, medium-load applications.

Material of Light Rail S20

 

Light Rail S20 is a European standard (DIN 5901) light steel rail with a weight of 19.8kg/m, primarily manufactured from carbon steel grades Q235B (for general, weldable use) or 55Q (for higher hardness and wear resistance). These materials ensure durability in industrial, mining, and light crane applications.

• Ideal for Specialized Infrastructure: They are commonly used in industrial sidings and for overhead crane runways, where they withstand dynamic loads from cranes and Automatic Guided Vehicles (AGVs).

 

• Precision and Compliance: Manufactured to adhere to DIN 5901 and EN 13674-1 standards, they offer high-quality, precise specifications with minimal tolerances (±0.1mm), ensuring compatibility with standard fastening systems.

 

• Customization and Cost-Efficiency: Suppliers often offer tailored services such as customized lengths, pre-drilled bolt holes, and special bevel cutting to minimize onsite waste and installation time.

 

• Low Maintenance: The robust, durable nature of the S20 rail reduces the need for frequent repairs or replacements in industrial settings.

 

• Material Options for Specific Needs: Available in different material grades, including high-strength 55Q steel which provides exceptional resistance to abrasion and deformation, suitable for high-traffic industrial tracks.

 

FAQ

 

• Is S20 rail exactly 20 kg?

No. The precise S20 steel rail weight is 19.80 kg/m. "20 kg" is a nominal category used for simplified communication.

 

• What is the height of an S20 rail?

The standard height for an S20 rail profile is exactly 100.00 mm.

 

• Is S20 rail the same as 20 lb rail?

No. "20 lb" refers to the American ASCE standard (approx. 9.92 kg/m), which is much lighter and smaller than the DIN 5901 S20 rail.

 

• Which material grade provides the best S20 rail load capacity?

The 55Q grade provides the highest RAIL S20 MATERIAL STRENGTH, allowing for safer and more durable load-bearing in industrial environments.
