New Prefabricated Housing

New prefabricated housing is a building form that uses industrialized production of building components and on-site assembly, featuring high efficiency, environmental protection, and high quality.

Construction Method: New prefabricated housing divides buildings into independent modules, which are manufactured in factories and then transported to the site for assembly. For example, components such as ceilings and walls are prefabricated in factories and assembled like building blocks. Through parallel operations, automated warehouses, and intelligent production lines, the construction period is shortened by more than 60% compared to traditional buildings. For instance, in a public housing project in Shenzhen, Guangdong, five residential buildings nearly 100 meters tall were assembled from 6,028 concrete modules, with the construction period reduced from 2.5 - 3 years to 1 year.

Structural Types:

1. Steel-Concrete Composite Structure: The steel usage is increased by 40% compared to traditional reinforced concrete structures, providing stronger load-bearing capacity and seismic resistance.
2. Other Structures: These include steel structures (lightweight, suitable for high-rise buildings and ocean transportation), concrete structures (close to traditional living experiences, with high acceptance in China), and wooden structures. For example, CMC composite module buildings enhance seismic resistance through integrated steel-concrete pouring, reducing the construction period by 30%.

Advantages and Characteristics:

1. Shortened Construction Period: On-site labor is reduced by about 50%, while also reducing noise, dust, construction waste, and traffic congestion that disturb residents.
2. Quality Control: Each component has a detailed 'ID card' recording project name, model, production date, and other information. The positioning accuracy of steel bars is measured in millimeters, with strict error control.
3. Energy Efficiency and Environmental Protection: With policy support, construction waste is reduced by more than 70%, aligning with the trend of green building development.
4. Strong Adaptability: Widely recognized in both domestic and international markets, in the first four months of 2026, the export value of mobile homes from the Guangzhou Customs area reached 1.4 billion yuan (a year-on-year increase of 38.1%), and exports from the Shenzhen port reached 1.68 billion yuan (a year-on-year increase of 19.6%).

Development History: China's prefabricated concrete technology began in the 1950s, initially used for factory and residential construction; in the 1970s, technical systems such as large-panel structures were formed; in the 1980s, development stalled due to cost and quality issues; after the 21st century, it has recovered due to advantages in efficiency and environmental protection. Since 2022, renovation policies have focused on repairs and upgrades, with only prefabricated panel houses meeting the criteria for dangerous buildings being demolished.
