Prefabricated Component Assembled Housing
Prefabricated component assembled housing is a building form that involves the industrial production of building components and their on-site assembly, characterized by high efficiency, environmental friendliness, and high quality.
Component Production and Connection Methods
Prefabricated component assembled housing transfers a significant amount of on-site work from traditional construction methods to factories. Building components and accessories, such as floor slabs, wall panels, stairs, and balconies, are processed and manufactured in factories and then transported to construction sites for assembly and installation using reliable connection methods, such as mechanical bolt connections. This approach enhances the precision and quality of component production while reducing errors and uncertainties in on-site construction.
Main Types and Technical Coverage
It mainly includes panel-type, box-type, and frame-type assembly. Panel-type buildings use prefabricated wall panels and floor slabs as core components; box-type assembly combines prefabricated functional units, increasing construction speed by 50%-70%, but requiring higher transportation and lifting equipment; modular buildings have a higher degree of integration, breaking down buildings into independent modules that are manufactured in factories and then assembled on-site. The technology covers prefabricated concrete structures and steel structures, with components including prefabricated beams, slabs, walls, and columns.
Significant Advantages
It offers advantages such as shortened construction periods, reduced pollution, conservation of resources and energy, and improved labor productivity and quality and safety levels. Compared to traditional construction methods, modular buildings can reduce construction periods by more than 60% and on-site labor by approximately 50%, significantly reducing noise, dust, construction waste, and traffic congestion at construction sites. Additionally, they provide controllable quality, energy efficiency, environmental friendliness, and ease of maintenance.
Abundant Application Cases
In Jiangbei, Ningbo, prefabricated components are connected using mechanical bolts, enabling ultra-fast on-site installation, with a prefabricated house assembled in just seven days. In Shenzhen, Guangdong, a public housing project featured five residential buildings nearly 100 meters high, assembled from 6,028 concrete modules, reducing the completion and delivery time from 2.5 to 3 years to just 1 year.
Broad Market Prospects
Chinese-made prefabricated houses are selling well overseas. According to customs data, in the first four months of 2026, the Guangzhou Customs District exported RMB 1.4 billion worth of mobile homes, a year-on-year increase of 38.1%. According to market research firm predictions, the global modular building market is expected to exceed USD 142.8 billion by 2030.
