Prefabricated Modular Housing

Prefabricated modular housing is a building form that involves the industrial production of building components and their on-site assembly, representing a more highly integrated prefabricated building model. Its core construction approach involves dividing the building into independent modules, completing the assembly-line prefabrication of components such as ceilings, floors, and water and electricity pipelines in factories, and then transporting them to the site for assembly, with the construction process resembling “building with blocks”.

The main advantages are reflected in the following aspects:

1. Significantly shortened construction periods: Compared with traditional methods, construction cycles can be reduced by 40%—60%. For example, a public housing project in Shenzhen, Guangdong, saw its completion and delivery time compressed from 2.5—3 years to 1 year through modular construction, representing an efficiency increase of over 60%.
2. Highly controllable quality: Construction precision reaches the millimeter level, with steel bar positioning errors controlled in millimeters, ensuring structural stability and building quality.
3. Outstanding energy-saving and environmental protection advantages: On-site labor is reduced by about 50%, with noise, dust, and construction waste reduced by over 70%. At the same time, it alleviates traffic congestion issues, aligning with green building development trends.
4. Enhanced maintenance convenience: Individual modules can be independently disassembled for inspection and repair, reducing interference with surrounding residents and extending the building's service life.

Technical types and component systems:

• Structural types: Cover panel-based, box-based, and frame-based prefabrication, with technical paths including prefabricated concrete structures and steel structures.
• Component types: Standardized products such as prefabricated beams, slabs, walls, and columns, enabling large-scale application through industrial production.

Wide range of application scenarios:
It has been maturely applied in fields such as public housing, rural residences, public facilities, and industrial buildings, and is suitable for special scenarios such as old residential area renovations, emergency housing, and industrial park dormitories, demonstrating high flexibility.

Industry development trends:
China's prefabricated concrete technology originated in the 1950s and saw a resurgence in the 21st century due to production efficiency and environmental protection needs. Currently, exports of Chinese-made prefabricated houses have grown significantly, with export value from the Guangzhou Customs area reaching 1.4 billion yuan in the first four months of 2026, a year-on-year increase of 38.1%. From 2015 to 2025, domestic prefabricated building exports nearly tripled, with export growth reaching 45% in the first quarter of 2026, indicating a broad market outlook.
