GB Light Rail is the "mainstay" of industrial transportation and urban rail transit. Its standardized specification system provides precise solutions for rail requirements in different scenarios. From 8KG to 30KG, each GB Light Rail has a strong adaptability through carefully designed specification parameters.
Key dimensions such as rail height, head width, and waist thickness are the core advantages of GB Light Rail. The 15KG light rail has a rail height of 79.37mm, a head width of 42.86mm, and a waist thickness of 8.33mm, which is suitable for light transportation; while the 30KG light rail has a rail height of 100mm, a head width of 65mm, and a waist thickness of 16mm. With larger size specifications, it can easily cope with heavy-load scenarios such as mines and steel mills. The scientific size design not only improves the load-bearing performance of the track, but also reduces wear and extends the service life of the track by optimizing the contact area between the wheel and the track.

In terms of materials, GB light rail mostly uses 55Q high-quality carbon steel or U71Mn series low-alloy steel. 55Q carbon steel has good strength and toughness, and is cost-effective; U71Mn low-alloy steel has higher strength, wear resistance and corrosion resistance, and can adapt to complex environments such as humidity and high temperature.
