Product Introduction

The light rails in the GB standard are special steel materials for railways produced through strict rolling processes, with a weight limit of 38kg or less per meter. During production, the provisions of the GB standard for rails must be followed, and the heating temperature, rolling passes, and cooling rate of the steel billets must be precisely controlled. After forming, more than 10 quality inspection processes such as ultrasonic flaw detection and hardness testing must be passed to ensure that there are no cracks inside the rails and that the surface hardness meets the standards, providing reliable track foundation materials for scenarios such as factory and mine railways and rural branch lines.

Q235B 55Q 12KG Light Rail are two common types of light rail.

Material Features

Q235B: It is a common carbon structural steel with low carbon content, good toughness, plasticity and welding performance, easy to process and form, and relatively low cost. But its strength, hardness and wear resistance are slightly worse than 55Q light rail.

55Q: It is a steel specially used for light rail. Its yield strength is basically the same as Q235B, but the carbon content is different. It performs better in toughness, tensile strength, impact strength and high temperature resistance. It can withstand greater forces and has good wear resistance. It is suitable for occasions with high requirements for track performance.

Product Packaging & Delivery

The export packaging and transportation of GB light rails follow the internationally accepted standardized operating procedures, the core of which is to ensure the safety and integrity of the products in the logistics process. In terms of packaging, the conventional practice is to use high-strength steel belts for tight bundling, and the weight of each bundle is controlled within a reasonable range of 3 to 5 tons. This specification design not only meets the operating standards of port lifting equipment, but also effectively utilizes the loading space of transportation tools. During bundling operations, special attention should be paid to spacing control, usually maintaining a spacing of less than 1.5 meters, and special anti-collision corner guards are installed at both ends of the rails. These measures together constitute a basic protection system that can resist mechanical shocks during conventional transportation.
