Prefabricated Structure Housing

Prefabricated structure housing, also known as prefabricated assembled buildings, is a form of construction that involves the industrial production of building components and their assembly on-site.

Main Types Prefabricated structure housing includes three major categories: panel-assembled, box-assembled, and frame-assembled types. Among them, modular construction represents a higher level of integration, where buildings are broken down into independent modules, manufactured in factories, and then transported to the site for assembly. For example, a public housing project in Shenzhen, Guangdong, assembled five residential buildings nearly 100 meters high using 6,028 concrete modules.

Technical Scope The technical system encompasses prefabricated concrete structures and steel structures, with components including prefabricated products such as beams, slabs, walls, and columns. Taking concrete modules as an example, the positioning accuracy of internal steel bars can reach the millimeter level. Each component is equipped with an 'ID card' that records information such as the project name, product model, and production date, ensuring quality control.

Core Advantages

1. Shortened Construction Period: The construction period can be reduced by more than 60%. For instance, the construction period of the Shenzhen public housing project was compressed from 2.5-3 years to 1 year, and the overall construction period of prefabricated buildings is 30% shorter than that of traditional methods.
2. Reduced Pollution: On-site noise, dust, and construction waste are reduced by more than 70%. Fujian Province has achieved the resource utilization of construction waste through the construction of industrial bases.
3. Quality Control: The industrial production model eliminates human errors, with component errors controlled in millimeters, improving the overall quality of the building.
4. Energy Efficiency and Environmental Protection: High material recycling rates meet green building standards.
5. Ease of Maintenance: Modular design facilitates later inspection, repair, and replacement.

Development History China's prefabrication technology began in the 1950s, with the formation of technical systems such as large-panel structures in the 1970s. It stagnated in the 1980s due to cost issues but revived in the 21st century due to environmental protection demands. Companies like Vanke Group have developed prefabricated shear wall residential structural systems, and the Nanjing Jindi Yufang project adopted pre-stressed prefabricated concrete frame technology. Traditional prefabricated panel houses have gradually been replaced by cast-in-place concrete and prefabricated buildings.

Market Prospects China's exports of prefabricated houses have grown significantly. In the first four months of 2026, the export value from the Guangzhou Customs area reached 1.4 billion yuan, a year-on-year increase of 38.1%; Shenzhen Port exported 1.68 billion yuan worth, a year-on-year increase of 19.6%. It is predicted that the global modular construction market size will exceed 142.8 billion US dollars by 2030.
