Product Introduction
GB light rail is a core material for railway tracks manufactured in strict accordance with China's national standard system. Its weight specifications cover eight grades: 8kg/m, 9kg/m, 12kg/m, 15kg/m, 18kg/m, 22kg/m, 24kg/m, and 30kg/m. In terms of material selection, high-quality carbon steel with a carbon content of 0.5% - 0.8% is mainly used. Some high-specification models will add alloying elements such as manganese (Mn) and silicon (Si) to form low-alloy steel to optimize the mechanical properties of the material.
During the production process, the steel billet needs to be heated to a high temperature state of 1100℃ - 1200℃, and then through multiple hot rolling processes such as rough rolling, intermediate rolling, and finishing rolling, it is gradually formed into a steel rail with a specific rail head, rail waist, and rail bottom structure. In terms of compressive strength, the finished GB light rail can withstand a pressure of 150-300MPa. After special surface treatment, it has good wear resistance and can effectively resist the loss caused by long-term wheel rolling. It is a basic component to support the stable operation of medium and low-capacity railway transportation systems.

55Q 15KG GB standard light rail is a common type of light rail.
Material characteristics: "55Q" indicates the material, which belongs to medium carbon steel. The carbon content of this steel is relatively high, which makes it have high strength and hardness, and can withstand certain pressure and impact. At the same time, 55Q steel also has good wear resistance, suitable for use in track environments with frequent use and certain friction.
Application scenarios: Mainly used for some railway lines with small transportation volume and low speed, such as internal transportation tracks in mines, factories, forest areas, etc., and can also be used in some cities' light rail transportation systems, such as sightseeing light rails, internal transportation tracks in small communities, etc.

Product Specifications

Product Packaging & Delivery
In view of the characteristics of the shipping environment, the rail packaging adopts a three-level protection standard. First, the entire surface is sprayed with anti-rust oil, and the oil film thickness is not less than 25μm. Then it is wrapped with 0.12mm thick anti-rust paper, and the seams are sealed with hot melt adhesive. The outermost layer is wrapped with waterproof woven cloth as a whole, and the seams are double-stitched and reinforced. Humidity indicator cards and desiccant are placed inside the package, and the amount of desiccant is 500g per cubic meter of space. After packaging is completed, it must pass a 72-hour salt spray test to ensure the protection effect during the shipping cycle.
