Steel Structure Prefabricated Panel

Steel structure prefabricated panels are an application form of prefabricated panels in steel-structured houses, characterized by their lightweight nature, suitability for ocean shipping, and use in high-rise buildings. Chinese companies hold a comparative advantage in this field.

I. Basic Concepts and Classifications
Steel structure prefabricated panels belong to the steel type within the "prefabricated housing" system. Prefabricated houses are mainly classified into steel, concrete, and wooden types, with Chinese companies demonstrating significant technical and cost advantages in steel and concrete sectors. Steel structure prefabricated panels use steel as the framework, combined with core materials such as cement and glass fiber, and are manufactured in factories before being transported to the site for assembly. This approach offers short construction periods and high standardization.

II. Product Characteristics and Specifications

1. Core Materials and Shapes: The core materials of steel structure prefabricated panels primarily consist of cement and glass fiber. Cement provides basic load-bearing capacity, while glass fiber enhances crack resistance and lightweight properties. In terms of shape, rectangular panels are the mainstream, with some special scenarios utilizing fibrous or irregularly shaped panels to accommodate complex structural requirements.
2. Flexural Strength: Depending on design requirements, flexural strength specifications vary widely, commonly ranging from 9.6×10⁴ MPa to 9.6×10⁵ MPa. High-strength specifications are suitable for high-rise buildings or large-span spaces, while low-strength specifications are used for low-rise residences or temporary structures.
3. Brands and Processes: Market-leading brands include Yongshi, Li'an, and Paipeng, with product differences primarily reflected in core material formulations, connection node designs, and anti-corrosion treatment processes. For example, some brands use galvanized steel frames combined with high-density cement to significantly enhance durability.

III. Pricing System and Influencing Factors
The price of steel structure prefabricated panels is significantly influenced by specifications, functions, and market positioning:

• Basic Products: Such as prefabricated container houses for foreign trade light steel villas, priced at approximately 90 yuan per 13 square meters, suitable for low-cost temporary housing or storage scenarios.
• Functionally Upgraded Products: Container activity rooms with glass curtain walls are priced at 239 yuan per square meter, meeting office or commercial display needs.
• High-End Modular Products: Detachable offices or construction site project department houses are priced at approximately 550 yuan per square meter, emphasizing rapid deployment and reusability.
  Price differences are also related to transportation costs, installation services, and customization levels. Ocean shipping projects typically require additional consideration for containerized packaging costs.

IV. Application Scenarios and Development Trends
Steel structure prefabricated panels are widely used in temporary buildings, low-rise residences, post-disaster reconstruction, and industrial plants. With the maturation of modular construction technology, their applications are expanding from single functions to integrated spaces, such as green building modules integrating photovoltaic power generation and intelligent temperature control systems. In the future, the integration of lightweight materials and digital design technologies will further drive cost reductions and performance improvements.
