Prefabricated Housing Factory Production

Prefabricated housing factory production is a building method that involves the industrial production of building components and their on-site assembly. Also known as prefabricated assembled buildings or modular buildings, it features high efficiency, controllability, environmental friendliness, and flexibility, making it an important direction for the transformation and upgrading of the construction industry.

Technical Characteristics and Core Advantages

The core of prefabricated housing factory production lies in breaking down buildings into independent modules or components (such as beams, slabs, walls, columns, etc.), which are manufactured on factory assembly lines and then transported to the construction site for assembly. Its advantages are significant:

1. Efficient Production: By adopting a parallel operation model and combining automated production lines with intelligent management, construction periods can be shortened by more than 50%-60%. For example, a public housing project in Shenzhen, Guangdong, was assembled from 6,028 concrete modules, reducing the construction period from 2.5-3 years to just 1 year. Another example is a police station office building in Guangzhou, which took less than a month from module hoisting to delivery.
2. Quality Control: Component curing is completed in the factory, avoiding weather interference and achieving millimeter-level production precision. The structural safety is equivalent to that of traditional cast-in-place buildings.
3. Environmental Protection and Energy Efficiency: Solid waste emissions throughout the entire lifecycle are reduced by 75%, on-site personnel are reduced by 70%, and dust, noise, and construction waste are significantly decreased.
4. Flexible Design: Modules can integrate ceilings, floors, water and electricity pipelines, etc., supporting a combination of standardization and customization to meet diverse needs.

Application Scenarios and Typical Cases

Prefabricated housing factory production has been widely applied in residential buildings, public buildings, overseas exports, and rural construction. For example, Vanke Group has developed a prefabricated shear wall residential structural system, and the Nanjing Jindi Yufang project uses a prestressed prefabricated concrete frame structure. The public housing project in Shenzhen, Guangdong, assembled from 6,028 modules, accommodates over 2,000 households. Additionally, Chinese prefabricated houses are in high demand overseas. In the first four months of 2026, the Guangzhou Customs district exported portable houses worth 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%, covering more than 150 countries and regions. In rural construction, prefabricated concrete houses are hoisted to complete the main structure, saving time and reducing noise.

Technical Classification and Challenge Countermeasures

Based on structural type, prefabricated housing factory production includes prefabricated concrete structures and steel structures. Based on integration level, it includes panel-assembled, box-assembled, frame-assembled, and modular buildings (with the highest integration level). Going overseas faces bottlenecks such as incompatible standards, high certification costs, and complex logistics and customs clearance. It is recommended to embed multi-standard adaptability capabilities into digital design platforms, promote the alignment of Chinese standards with international ones, and establish an overseas certification resource-sharing platform in collaboration with the industry. In terms of industrial support, it is necessary to improve the technical system, production system, and industrial clusters to support large-scale applications.
