Fully Prefabricated Assembled Housing

Fully prefabricated assembled housing is a construction model that breaks down buildings into independent modules, prefabricates them in factories, and then transports them to the site for assembly. It offers advantages such as short construction periods, controllable quality, energy conservation, and environmental protection, with broad market prospects.

Construction Model and Process Characteristics

Fully prefabricated assembled housing employs modular design, with components such as ceilings, walls, floors, plumbing and electrical systems, and even bathroom waterproofing layers prefabricated on factory assembly lines. Each module is equipped with a detailed 'ID card' indicating project name, product model, production date, and other information. The position of steel bars is controlled with millimeter-level precision to ensure component standardization and installation accuracy. On-site construction simply involves assembling modules like 'building blocks', significantly simplifying the traditional construction process.

Core Advantages

1. Construction Period and Efficiency: Compared to traditional construction, the construction period is significantly shortened. For example, the completion and delivery time of a certain affordable housing project was reduced from 2.5-3 years to 1 year, with on-site labor reduced by about 50%, effectively lowering labor costs.
2. Quality Control: Factory production eliminates variables such as weather and manual operation errors, ensuring stable component quality and high precision in pre-embedded plumbing and electrical systems, reducing the risk of later maintenance.
3. Environmental Benefits: On-site construction noise, dust, and construction waste are reduced by about 70%, alleviating traffic congestion issues and meeting green building standards.
4. Maintenance Convenience: Modular design supports quick local replacement. For example, if components such as walls or floors are damaged, they can be individually removed and repaired, extending the overall lifespan of the building.

Development History and Market Status

China's prefabricated concrete technology began in the 1950s, initially used for factory and residential construction, and saw a resurgence and widespread application in the 21st century due to environmental protection needs. Currently, exports of Chinese-made prefabricated houses have grown significantly: In the first four months of 2026, the Guangzhou Customs District exported 1.4 billion yuan worth of mobile homes (a year-on-year increase of 38.1%), and the Shenzhen Port exported 1.68 billion yuan worth (a year-on-year increase of 19.6%), covering more than 150 countries and regions. It is predicted that the global modular construction market will exceed 142.8 billion USD by 2030, driven by factors such as accelerated urbanization, stricter environmental policies, and technological advancements.
