Products Description
China standard 50kg heavy rail is a type of rail that complies with the provisions of China's national standards and is usually used for ordinary railways, regional railways and some freight railway lines. Its specification is 50 kg per meter of rail. This rail has good load-bearing capacity and durability and is suitable for medium-load railway use.
50kg steel rails are mainly produced from high-quality carbon steel or alloy steel. The chemical composition and mechanical properties of the rails are strictly specified according to the standards, and usually contain a certain proportion of elements such as carbon, silicon, manganese, sulfur and phosphorus to ensure the strength, toughness and wear resistance of the rails.
Steel rails are usually produced by hot rolling. During the production process, the billet is heated and rolled into shape in the rolling mill, and the size and shape of the rails are adjusted through cooling, correction and other processes.

2. Do different types of railways require different rails?
Answer: Yes, different types of railways (such as high-speed railways, heavy-duty railways and light rails) need to choose rails of different specifications and materials according to the load-bearing capacity and speed requirements.
3. What is the standardization and quality certification of rails?
Answer: The standardization of rails refers to the production and use of rails in accordance with international or national regulations. Common quality certifications include ISO9001 and other quality management system certifications to ensure that products meet relevant standards.
