Haimin Prefabricated Housing
Haimin prefabricated housing can refer to relevant information about China's 'prefabricated houses'. In essence, it is modular construction, which offers advantages such as short construction periods and controllable quality, but requires a high level of industrial foundation and has broad market prospects.
Construction Mode and Production Efficiency Prefabricated houses adopt a modular construction mode, dividing buildings into independent modules (such as ceilings, walls, bathroom waterproof layers, etc.), which are manufactured in factories and then transported to the site for assembly. Taking the China State Construction Hailong Intelligent Construction Industrial Park in Shenzhen, Guangdong as an example, its intelligent production lines and automated three-dimensional warehouses support parallel operations, enabling the delivery of 20,000 to 30,000 modules annually. The construction period is shortened by more than 60% compared to traditional buildings. This mode significantly improves construction efficiency through standardized processes and industrialized production.
Price and Market Performance Prefabricated houses are competitively priced, with a basic model costing only 200,000 yuan (including transportation costs). China's exports of prefabricated buildings have grown rapidly, with a 45% increase in export growth in the first quarter of 2024. Guangdong Customs reported export earnings of 1.4 billion yuan in the first four months, a year-on-year increase of 38.1%. This trend reflects the rising global demand for modular construction, especially the urgent need for fast and low-cost housing solutions in developing countries.
Core Advantages
- Short Construction Period: Factory prefabrication and on-site assembly are carried out in parallel, significantly shortening the construction cycle.
- Controllable Quality: Standardized production reduces human errors, ensuring stable material and process quality.
- Energy Efficiency and Environmental Protection: Centralized factory production reduces on-site waste, and modules can be reused.
- Convenient Maintenance: Modular design facilitates later maintenance and upgrades, reducing the total lifecycle cost.
Industrial Challenges Modular construction places extremely high demands on the industrial foundation, requiring the establishment of a complete technical system (such as structural connection technology), production system (such as automated production lines), and industrial clusters (such as supply chain collaboration). Currently, only a few regions with industrial foundations and policy support (such as the Yangtze River Delta and Pearl River Delta in China) can achieve large-scale applications.
Market Prospects According to market research institutions, the global modular construction market is expected to exceed $142.8 billion by 2030. With technological iterations and cost optimizations, prefabricated houses are expected to further popularize in residential, commercial, and emergency construction fields, becoming an important development direction for the future construction industry.
