    Product Of Advantages

    The main features of   include:

    Processing properties:   have low hardness, are easy to process, and have good ductility. This makes it easier to shape and bend during processing.

    Mechanical properties: Due to the softening of steel at high temperatures, hot rolling can improve the internal structure of the steel, making it tighter and stronger, thereby enhancing the mechanical properties. At the same time, under the action of high temperature and pressure, defects within the steel such as bubbles, cracks and looseness can be welded.

    Surface quality: The surface quality of  is relatively poor because an oxide layer is easily formed on the surface during the hot-rolling process and the smoothness is low.

    Strength and toughness: Hot-rolled steel plates have relatively low strength, but good toughness and ductility. It is usually used to produce medium-thick plates and is suitable for applications requiring better plasticity.

    Thickness: Hot-rolled steel sheets can be of greater thickness, in contrast, cold-rolled steel sheets are usually smaller.

    Application fields: Hot-rolled steel plates are often used in the production of structural steel, weather-resistant steel, automobile structural steel, etc., and are suitable for the production of various mechanical parts and the manufacture of high-pressure gas pressure vessels.

    Main Application

    application

    Application of Hot Rolled Steel Plate

    1. Construction field: Hot-rolled steel plates are often used in support, floor, wall panels and roofs of building structures, including large buildings such as bridges and high-rise buildings.

    2. Automobile manufacturing field: hot-rolled steel sheets occupy an important position in the automobile manufacturing process, and their main uses are to manufacture body structures, doors, covers and other components.

    3. Energy field: hot-rolled steel plates are used to manufacture energy facilities such as power plants, transmission towers and oil pipelines.

    4. In the field of machinery manufacturing: hot-rolled steel plates can be used to manufacture machine tools, robots and other industrial equipment.

    1.Free sampling, 100% after-sales quality assurance, Support any payment method;
    2.All other specifications of round carbon steel pipes are available according to your requirement (OEM&ODM)! Factory price you will get from ROYAL GROUP.

    Process of production

    Hot rolling is a mill process which involves rolling the steel at a  high temperature

    which is above the steel’s recrystallization temperature.

    Packing and Transportation

    Packaging is generally naked, steel wire binding, very strong.
    If you have special requirements, you can use rust proof packaging, and more beautiful.

    Steel plate weight limit
    Due to the high density and weight of steel plates, appropriate vehicle models and loading methods need to be selected according to specific conditions during transportation. Under normal circumstances, steel plates will be transported by heavy trucks. Transport vehicles and accessories must comply with national safety standards, and relevant transport qualification certificates must be obtained.
    2. Packaging requirements
    For steel plates, packaging is very important. During the packaging process, the surface of the steel plate must be carefully inspected for slight damage. If there is any damage, it should be repaired and reinforced. In addition, in order to ensure the overall quality and appearance of the product, it is recommended to use professional steel plate covers for packaging to prevent wear and moisture caused by transportation.
    3. Route selection
    Route selection is a very important issue. When transporting steel plates, you should choose a safe, calm and smooth route as much as possible. You should try your best to avoid dangerous road sections such as side roads and mountain roads to avoid losing control of the truck and overturning and causing serious damage to the cargo.
    4. Arrange time reasonably
    When transporting steel plates, time should be reasonably arranged and sufficient time reserved to deal with various situations that may arise. Whenever possible, transportation should be carried out during off-peak periods to ensure transportation efficiency and minimize traffic pressure.
    5. Pay attention to safety and security
    When transporting steel plates, attention should be paid to safety issues, such as using seat belts, checking vehicle conditions in a timely manner, keeping road conditions clear, and providing timely warnings on dangerous road sections.
    In summary, there are many things that need to be paid attention to when transporting steel plates. Comprehensive considerations must be made from steel plate weight restrictions, packaging requirements, route selection, time arrangements, safety guarantees and other aspects to ensure that cargo safety and transportation efficiency are maximized during the transportation process. Best condition.
