2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load
3. Marks:
Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.
Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, size, length, grade, made in China, shipping marks and other information request by the customer.
If loading by container the marking is not needed, but we will prepare it as customer request.
4. Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load.

- Q:How do steel rails contribute to noise reduction in trains?
- Steel rails contribute to noise reduction in trains in several ways. Firstly, steel is a dense and strong material, which allows for a smooth and stable surface for the train wheels to run on. This reduces the vibrations and impact between the wheels and the tracks, thereby minimizing noise production. Additionally, steel rails are designed with specific profiles, such as the "Vignole" rail profile, which helps to reduce noise. The curved shape of the rail profile helps to minimize the contact area between the wheels and the rail, resulting in less friction and noise generation. This design also helps to distribute the weight of the train more evenly, reducing the impact on the tracks and further reducing noise. Moreover, steel rails are subjected to regular maintenance to ensure they remain in optimum condition. This maintenance includes regular grinding and lubrication of the rails to reduce friction and noise. Grinding smoothens out any irregularities on the rail surface, while lubrication reduces the friction between the wheels and the rails, resulting in quieter operation. Furthermore, steel rails are often installed on resilient track systems, which incorporate elastic elements to absorb and dampen vibrations. This helps to further reduce noise by minimizing the transmission of vibrations from the rails to the ground. In summary, steel rails contribute to noise reduction in trains through their dense and strong nature, specific rail profiles, regular maintenance, and resilient track systems. These factors work together to minimize vibrations, friction, and impact, resulting in quieter train operations.
- Q:Can steel rails be used in high-capacity railways?
- Steel rails are indeed capable of being used in high-capacity railways. In fact, they are the most widely utilized material for railway tracks across the globe due to their robustness, power, and affordability. Steel rails possess the capacity to endure substantial loads and intense pressure, rendering them suitable for high-capacity railways where trains transport significant quantities of passengers or goods. Moreover, steel rails exhibit exceptional resistance to wear and tear, guaranteeing a lengthier lifespan and reducing the expenses associated with maintenance and replacement. The adaptability and versatility of steel rails additionally facilitate seamless and efficient train operations, permitting high-capacity railways to transport large volumes of individuals or commodities over extended distances with utmost efficiency.
- Q:How are steel rails manufactured to withstand high impact forces?
- Steel rails are manufactured to withstand high impact forces through a combination of careful design, high-quality materials, and precise manufacturing processes. The rails are typically made from a special grade of steel that exhibits excellent strength and durability. They undergo processes such as hot rolling, which involves heating the steel and then shaping it into the desired rail profile. Additionally, the rails may undergo heat treatment or other techniques to further enhance their hardness and toughness. These manufacturing methods ensure that the steel rails can withstand the significant impact forces exerted by heavy trains, thereby ensuring their longevity and safety.
- Q:Are steel rails used in urban transportation systems?
- Yes, steel rails are commonly used in urban transportation systems, such as subways, trams, and light rail systems, due to their durability, strength, and ability to withstand heavy loads and frequent use.
- Q:What are the advantages of continuous welded steel rails?
- Continuous welded steel rails have several advantages. Firstly, they provide a smoother and more comfortable ride for trains, reducing vibrations and noise. This improves passenger comfort and overall safety. Secondly, the continuous welding eliminates the need for track joints, which reduces maintenance requirements and enhances the overall durability of the rail system. Additionally, the absence of joints decreases the risk of derailments and increases the speed at which trains can safely travel. Lastly, continuous welded steel rails offer better electrical conductivity, ensuring efficient power transmission for electric trains and reducing the risk of power loss. Overall, these advantages make continuous welded steel rails a preferred choice for modern rail systems.
- Q:How are steel rails affected by extreme weather conditions?
- Steel rails can be affected by extreme weather conditions in various ways. For instance, during hot weather, steel rails can expand, causing them to buckle or warp. In cold weather, they can contract and become more brittle, potentially leading to cracks or fractures. Additionally, extreme weather conditions such as heavy rain, snow, or ice can corrode the rails, compromising their strength and integrity. Thus, it is crucial to regularly inspect and maintain steel rails to ensure safe and efficient railway operations in all weather conditions.
- Q:How do steel rails contribute to the overall efficiency of railways?
- Steel rails contribute to the overall efficiency of railways by providing a smooth and durable surface for train wheels to roll on. They help distribute the weight of the train evenly, reducing friction and allowing for higher speeds and greater carrying capacity. Additionally, steel rails are resistant to wear and tear, minimizing the need for frequent maintenance and ensuring reliable and safe transportation.
- Q:What is the average density of steel rails?
- The average density of steel rails is approximately 7,800 kilograms per cubic meter (kg/m³).
- Q:Can steel rails be used in railway sidings or spurs?
- Yes, steel rails can be used in railway sidings or spurs. Steel rails are commonly used in railway tracks due to their durability, strength, and ability to withstand heavy loads. Railway sidings or spurs are essentially additional tracks branching off the main railway line, and steel rails are suitable for these applications as well.
- Q:How are steel rails protected against buckling?
- Steel rails are protected against buckling through a combination of factors such as proper design and construction techniques, regular maintenance, and monitoring systems. One common approach is the use of continuous welded rails (CWR) which reduce the number of joints and increase the stability of the track. Additionally, the rails are often placed on a stable and well-constructed foundation, minimizing the risk of buckling. Regular inspections and maintenance help identify any potential issues and allow for timely repairs or replacements. Monitoring systems such as track circuits or temperature sensors are also employed to detect abnormal conditions, enabling prompt interventions to prevent buckling.
