Fully Prefabricated Housing

Fully prefabricated housing is a building form that adopts a modular construction model, where the building is disassembled into independent modules, prefabricated in factories, and then assembled on-site. It offers advantages such as short construction periods, controllable quality, and energy conservation and environmental protection.

Technical Coverage and Component Types

Fully prefabricated housing technology encompasses prefabricated concrete structures and steel structures. Components include prefabricated products such as beams, slabs, walls, and columns. These components are manufactured on factory assembly lines and achieve modular production through standardized design, ensuring compatibility and interchangeability among various parts. For example, wall modules can integrate insulation and soundproofing functions, while water and electricity pipeline modules have pre-reserved interfaces, reducing on-site construction errors.

Core Advantages

1. Shortened Construction Period: Modular construction enables parallel operations of factory prefabrication and on-site assembly, reducing the construction period by 30%-60% compared to traditional buildings. For instance, in a public housing project in Shenzhen, Guangdong, five nearly 100-meter residential buildings were assembled using 6,028 concrete modules, compressing the construction period from 2.5-3 years to just 1 year.
2. Controllable Quality: Each prefabricated component is equipped with an 'ID card' that records the project name, product model, production date, and steel bar positioning information, with error control measured in millimeters. Standardized production in a factory environment avoids human interference from on-site construction, significantly improving building quality.
3. Energy Conservation and Environmental Protection: Factories employ automated production lines and vertical warehouses, reducing on-site noise, dust, and construction waste. Fujian Province has established industrial bases with policy support, achieving a reduction in construction waste of over 70% while alleviating traffic congestion.
4. Easy Maintenance: Modular design supports rapid replacement of local components, offering high maintenance flexibility. For example, steel structure modules can be disassembled and reorganized to adapt to different functional requirements, expanding application scenarios.

Main Forms and Market

Fully prefabricated housing primarily consists of steel structures, concrete structures, and wooden structures. Chinese companies hold a comparative advantage in the steel and concrete sectors. Steel structures are lightweight and suitable for ocean transportation and high-rise buildings; concrete structures offer a traditional living experience and are well-received in the domestic market. In terms of the market, Chinese-made prefabricated houses are selling well overseas. In the first four months of 2026, the Guangzhou Customs district exported movable houses worth 1.4 billion yuan, a year-on-year increase of 38.1%; the Shenzhen port exported 1.68 billion yuan worth, a year-on-year increase of 19.6%. It is predicted that the global modular construction market will exceed $142.8 billion by 2030.
