Product Introduction
Light rail under GB standard is a railway track material made of carbon steel or low alloy steel, covering a variety of specifications from 8 to 30kg/m. The production process strictly follows the GB/T 11264 specification, and by controlling the ratio of carbon and manganese elements, the rail has good compression resistance and wear resistance. Among them, the yield strength of 8-12kg/m specifications is above 300MPa, which is suitable for low-load short-distance transportation; the tensile strength of 30kg/m specifications exceeds 550MPa, which can meet the medium-volume transportation needs of urban light rail branches.
GB 15 kg light rail implements GB/T 11264 standard, and its core size parameters are optimized. The cross-sectional structure forms an "I"-shaped cross-section. This structure reduces its own weight while ensuring bending strength by reasonably distributing materials. The theoretical weight per unit length is 15.2kg/m, which is convenient for manual handling and short-distance transportation.
15KG light rail often uses two materials, Q235B and 55Q. Q235B has a carbon content of about 0.2% and a yield strength of ≥235MPa. It has good plasticity, weldability and processability. It is suitable for temporary tracks or light load scenarios (such as construction site access roads and small warehouse transportation lines). It has low cost and is easy to maintain.
55Q is a medium carbon steel with a tensile strength of ≥685MPa. Its wear resistance and impact resistance are significantly better than Q235B. It is suitable for frequently used tracks (such as long-term transportation lines in mining and forest areas), and its service life can be extended by more than 30%.

Product Packaging & Delivery
GB light rails generally use professional bundling and packaging technology in export transportation. Standard bundling uses 32mm wide galvanized steel strips, and a bundling point is set every 1.2 meters to ensure that there is no displacement during transportation. The bundling tension is strictly controlled within the range of 5500-6000N, and all bundling points must pass a 48-hour vibration test. 3mm thick steel corner guards must be installed at both ends of the rails, and the length of the corner guards must be no less than 1.5 times the height of the rails. The weight of each bundle of rails is uniformly controlled at 4±0.5 tons to meet the operating requirements of standard loading and unloading equipment.
As a professional manufacturer of GB standard light rails in China, GNEE RAIL has a complete production system and strict quality control process. The factory is equipped with multiple sets of modern rolling equipment and adopts standardized production processes to ensure that the product size accuracy and performance stability meet national standards. From the entry of raw materials to the delivery of finished products, each production link has strict quality control points to ensure that the products meet the GB/T11264 standard.
