In the field of modern transportation and industry, 30KG light rail, as a common light rail, plays an indispensable role. Its unique design and performance make it widely used in many scenarios.
1. Key parameters
30KG light rail has precise parameter standards in design. Generally speaking, the rail height is 107.95mm, the bottom width is also 107.95mm, the head width is 60.33mm, the waist thickness is 12.3mm, and the theoretical weight is 30.1kg/m. Such a combination of parameters ensures that the rail can maintain good stability and durability when subjected to pressure and impact, and provides reliable support for various vehicles running on it.

2. 30KG Light Rail Common Materials
30kg light rail made of Q235B: This is a commonly used ordinary rail material. It has good overall performance and is relatively affordable. It is suitable for general use scenarios without special requirements and can meet the needs of conventional light rail operations.

3.P30 Light Steel Rail Application areas
Urban public transportation: 30KG light rail is widely used in urban light rail transportation systems and tram lines. It provides urban residents with an efficient, convenient and environmentally friendly way of travel, effectively alleviates urban traffic pressure, and improves the carrying capacity of public transportation.

Mine transportation: Due to its good carrying capacity and adaptability to harsh environments, 30KG light rail is an ideal choice for material transportation within mines. The mining environment is complex and the transportation tasks are heavy. The 30KG light rail made of 55Q material can meet long-term and high-intensity transportation needs with its advantages of wear resistance and high hardness, and ensure the efficient transportation of materials such as ores.
