Products Description
The theoretical weight per meter of a 22kg steel rail is 22 kilograms, which is one of its most prominent markings, distinguishing it from other weight specifications such as 38kg/m, 43kg/m, 50kg/m, 60kg/m, etc.
Due to the low load-bearing capacity of 22kg steel rails, they are not suitable for high-speed railways or railway systems that carry heavy trains.When selecting 22kg steel rails, it is necessary to ensure their safety and applicability based on specific usage requirements, especially train weight, operating speed, and traffic frequency
Size:
The rail height is generally 107mm
The bottom width is 92mm
The head width is 51mm
The waist thickness is 10.9mm
22kg steel rails require high strength and hardness to withstand the heavy pressure and impact of trains, while also having good toughness and wear resistance to extend their service life.

Other Features
Material characteristics of national standard steel rails
National standard steel rails are an important component of railway transportation, and their material properties directly affect the safety and efficiency of railway operation. National standard steel rails are mainly made of high-quality carbon structural steel or low-alloy structural steel, which have high strength, high toughness, and good wear resistance, and can withstand the enormous pressure and friction during train operation.
Specifically, the material of the national standard steel rail should meet the following requirements: firstly, the chemical composition of the steel must be strictly controlled to ensure the mechanical properties and corrosion resistance of the rail; Secondly, the physical properties of steel rails, such as tensile strength, yield strength, elongation, etc., must meet national standards to ensure the stability and safety of the rails during use; Finally, the production process of steel rails also needs to comply with regulatory requirements to ensure consistency and reliability of product quality.
