Semi-Finished Housing Prefabricated Components
Semi-finished housing prefabricated components are a core part of the prefabricated construction field. They are produced industrially and assembled on-site, offering advantages such as shortened construction periods and reduced pollution, and are widely applied in various fields domestically and internationally.
Technical Types and Component Composition
The technical systems of semi-finished housing prefabricated components mainly include two major categories: prefabricated concrete structures and steel structures. Their components cover the core parts of building structures, such as prefabricated products like beams, slabs, walls, and columns. These components are designed to standard specifications and produced in factories, ensuring dimensional accuracy and quality stability, providing a foundation for rapid on-site assembly.
Price Differences and Influencing Factors
The prices of prefabricated components vary significantly by region and type. For example, the price of modular integrated housing office building assembled movable cement panel houses in Suining, Xuzhou, Jiangsu is 368.00 yuan per square meter; the prices of cement box houses and cement mobile houses in Baoding, Hebei are mostly 255.00 yuan per square meter or 260.00 yuan per square meter; the customized villa panel houses for Hengjian movable houses in Maoming, Guangdong are priced per set at 10,500 yuan. Price differences mainly stem from factors such as material costs, transportation distances, component complexity, and regional market demand.
Application Scenarios and International Development
Prefabricated components have penetrated various fields domestically and internationally. Domestically, the renovation project of the dilapidated building at No. 8 Huapichang Hutong in Xicheng District, Beijing, adopted modular integrated construction technology, significantly improving construction efficiency. In the international market, Chinese prefabricated houses have been exported to more than 160 countries and regions worldwide, with total export value reaching 2.79 billion US dollars in the first half of 2026, a year-on-year increase of 45%. Typical cases include: remote mining areas in Australia importing Chinese modular housing, reducing costs by about 30% compared to local construction; and a Philippine developer utilizing Chinese "prefabricated house" technology to complete a 12-story fully furnished apartment building in just 9 days.
Production Efficiency and Industrial Advantages
Taking Modular Integrated Construction (MiC) as an example, its production efficiency is extremely high. In the Shenzhen Longgang Intelligent Construction Industrial Park, more than 80 intelligent equipment units work in coordination, producing a fully equipped building module every 20 minutes. After being transported to the construction site, the module can be installed in just 30 minutes, significantly shortening the traditional construction cycle while reducing on-site wet operations and construction waste, aligning with the trend of green building development.
