prefab steel structure

Core Parameters
Steel Types
Mainly Q235 and Q345 steels are selected. Q235 steel has high cost - effectiveness, good plasticity and weldability, and is suitable for general load environments, such as ordinary small - scale buildings or parts with low requirements for structural strength. Q345 steel has significantly higher strength and better toughness, and can handle large loads and complex stress conditions. It is often used in projects with strict requirements for structural stability and bearing capacity, such as large - scale industrial plants and high - rise buildings.
Specifications of Structural Components
- **Steel Columns**: Common cross - sectional forms include H - shaped, circular, and box - shaped. H - shaped steel columns are widely used. Their cross - sectional height is usually 200 - 1000mm, flange width is 150 - 600mm, and the thickness of the web and flange is calculated according to the force, ranging from 6 - 25mm. The diameter of circular steel columns is generally 200 - 1000mm, and the side length of box - shaped steel column cross - sections is 300 - 1000mm. The length of steel columns is customized according to the building height, usually 3 - 15 meters.
- **Steel Beams**: Most are H - shaped cross - sections. The beam height is generally 1/10 - 1/18 of the span. For example, for a steel beam with a span of 10 meters, the beam height may be 550 - 1000mm, and the width is 1/2 - 1/3 of the height. The length of the steel beam is determined according to the internal layout of the building and the span requirements, commonly 6 - 24 meters.
- **Enclosure System**: Color - coated steel sheets are often used for roofs and walls, with a thickness of 0.4 - 0.8mm, having good waterproof, heat - insulation, and corrosion - resistant properties. For buildings with high insulation requirements, sandwich color - coated steel sheets are selected, with a core material thickness of 50 - 150mm. Core materials such as polystyrene and polyurethane can greatly improve the heat - insulation effect.
Connection Methods
Mainly bolt connection is used, supplemented by welding in some key parts. Bolt connection is convenient for quick on - site assembly, improves construction efficiency, and is easy to disassemble, which is beneficial for later renovation and maintenance. High - strength bolts can provide reliable connection strength to ensure the integrity of the structure. Welding enhances the rigidity and stability of the structure, especially suitable for parts with high requirements for joint strength.
Product Advantages
- **Fast Construction Speed**: All components are pre - fabricated in the factory. After being transported to the site, the building structure can be quickly erected through simple assembly operations. This prefabricated construction method greatly shortens the construction period. Compared with traditional construction methods, it can save 30% - 50% of the time, enabling the building to be put into use faster.
- **Stable and Reliable Quality**: The factory production environment is stable, and advanced processing equipment and a strict quality control system are used to accurately control the dimensions and quality of components. Each component is strictly tested before leaving the factory to ensure compliance with design standards and relevant industry regulations. This reduces the impact of on - site construction human factors and environmental factors on quality, providing long - term stable structural protection for the building.
- **Flexible Space Layout**: The pre - fabricated steel structure has an open internal space and flexible column grid layout. It can be divided and arranged in various ways according to different building functional requirements. Whether it is a large - space industrial plant, a warehousing center, or a small - bay office building or residence, it can be easily achieved, improving space utilization.
- **Recyclable and Environment - friendly**: Steel is a recyclable material. After the building is demolished, the pre - fabricated steel structure components can be recycled and re - processed, which is in line with the concepts of environmental protection and sustainable development. At the same time, the factory pre - fabrication process can effectively reduce the generation of construction waste and reduce environmental pollution.
- **High Cost - effectiveness**: On the one hand, the short construction period reduces labor costs, equipment rental costs, and the capital occupation cost during the project construction process. On the other hand, the standardized production and installation process of pre - fabricated steel structures is convenient for cost control, with a low material loss rate, and the overall construction cost is competitive. In the long run, its recyclable characteristics also reduce the life - cycle cost of the building.
Selling Points Concerned by Purchasers
- **Customized Service**: According to the purchaser's building use (such as industrial production, commercial office, residential, etc.), site conditions (terrain, area, geological conditions, etc.), budget constraints, and building style preferences, a comprehensive customized design plan is provided. From structural selection, component size determination to enclosure system configuration and interior decoration suggestions, it meets the purchaser's personalized needs, ensuring that the building not only meets functional requirements but also has a unique appearance.
- **One - stop Solution**: Provide a one - stop service from design, production, transportation to installation. Purchasers do not need to connect with multiple suppliers, simplifying the project management process. A professional team is responsible for the promotion of the entire project, coordinating the work of each link to ensure the smooth progress of the project, saving time and effort for purchasers.
- **Technical Support and Training**: Provide comprehensive technical support to purchasers, including technical guidance during construction and structural maintenance training. Professional technicians can help purchasers solve any technical problems encountered during installation and use, ensuring the normal use and long - term maintenance of the building. At the same time, training services enable relevant personnel of purchasers to be familiar with the characteristics and maintenance methods of pre - fabricated steel structures, improving the service life and safety of the building.
- **After - sales Service Guarantee**: Provide a complete after - sales service, including regular follow - up visits, quality warranty, and repair services. During the use of the building, if any quality problems occur, the after - sales service team will respond in a timely manner and provide solutions to ensure that purchasers have no worries. At the same time, establish a long - term customer relationship, and provide technical consultation and upgrade and renovation suggestions to purchasers at any time to meet the ever - changing needs of purchasers.
