Prefabricated Assembly-Type Housing Factory

A prefabricated assembly-type housing factory is a construction production site that produces building components through industrial methods and assembles them on-site, with the core characteristic of 'building houses like making cars'.

I. Production Mode and Process
The factory adopts a standardized and modular production mode, breaking down buildings into components such as concrete wall panels, stairs, and beams and columns, and completing manufacturing through assembly-line operations. Taking Broad Homes as an example, its process covers concrete mixing, U-shaped steel bar processing, steel bar truss welding, prefabricated cement panel and stair production, and other links. It precisely controls temperature and humidity through curing kiln rooms, enabling components to reach lifting strength within 8-12 hours. The China State Construction Hailong Intelligent Construction Industrial Park in Shenzhen, Guangdong, completes module assembly through welding manipulators and highly automated final assembly platforms, with an annual production capacity of 20,000-30,000 modules and a construction period reduced by more than 60% compared to traditional buildings.

II. Technical Characteristics and Quality Control
The factory integrates automated vertical warehouses and intelligent production lines through a parallel operation mode, achieving simultaneous advancement of multiple links. Component production employs millimeter-level precision control, with an error range far below traditional construction standards. Each prefabricated module is labeled with information such as project name, model, and production date, forming a traceable quality management system. For example, the Ningbo Jiangbei Fully Prefabricated Rural Housing Project uses mechanically bolted plate-type structural components, completing on-site assembly in 7 days, verifying the assembly efficiency of high-precision components.

III. Typical Cases and Benefits
A real estate project in Shanghai used 6,028 concrete modules to assemble a residential building nearly 100 meters high, compressing the construction period from 2.5-3 years to 1 year and reducing on-site labor by about 50%. This factory model has driven a reduction in construction waste by more than 70% and facilitated the export of Chinese prefabricated houses overseas. In the first four months of 2026, exports of mobile houses from the Guangzhou Customs district increased by 38.1% year-on-year, demonstrating their international market competitiveness.

IV. Industry Significance
Prefabricated assembly-type housing factories have addressed issues such as long construction periods, heavy pollution, and unstable quality in traditional construction through industrial production, driving the construction industry towards green and low-carbon transformation. Its standardized production mode provides a replicable solution for construction industrialization and has become an important support for modern urban construction.
