Products Description
The 50kg steel rail is a standard type of railway rail. Its most distinctive characteristic is its weight of 50 kg per meter, which makes it ideal for medium-load railway tracks. While heavier rails typically support greater train weights and higher speeds, the 50kg rail offers moderate load-bearing capacity.
This type of rail is primarily used in medium-load railways, including conventional railways, regional lines, and certain freight routes. It can handle the weight and traffic of standard trains and is well-suited for non-extreme heavy-load transport applications.
In some scenarios, 50kg rail is also appropriate for light rail and urban transit systems (such as subways), particularly where the operational loads are not excessively high.
About the size parameters of 50kg rails:
Rail height 152mm
rail bottom width 132mm
rail head width 70mm
rail waist thickness 15.5mm.

Other Features
GB 50kg steel rails offer excellent wear resistance and strength, being manufactured from high-quality alloy or carbon steel. They are designed to endure prolonged friction and pressure from train wheels while maintaining performance in long-term operating conditions.
The rail surfaces undergo specialized treatments, such as hardening, to improve durability and extend service life.
These rails support medium-weight freight and passenger trains, making them suitable for standard freight, passenger transport, and general railway operations. While not intended for ultra-heavy loads (such as heavy-haul freight or high-speed rail tracks), they effectively meet the demands of most conventional railway applications.

FAQ
1. What are the transportation methods for rails?
Answer: Rails can be transported by sea, rail, truck, etc. Sea transportation is usually used for long-distance international transportation, while rail and truck are suitable for domestic transportation.
2. How is the price of rails determined?
Answer: The price of rails is usually determined by factors such as specifications, materials, order volume, production process, and transportation method. Bulk orders usually enjoy lower unit prices.
3. How are rails packaged?
Answer: Rails are usually bundled with steel straps and packaged into strips for easy transportation and storage. Customized packaging can also be provided according to customer needs.
4. How to ensure the safety of rails during transportation?
Answer: Rails are usually reinforced during transportation, and anti-rust and anti-collision measures are taken during transportation to ensure that they are not damaged when they arrive at the destination.
