Prefabricated Concrete Structure Housing

Prefabricated concrete structure housing is a technical type of prefabricated housing (prefabricated modular construction). It involves the industrial production of building components and on-site assembly, offering significant advantages such as shortened construction periods and reduced pollution.

Technical Types and Components

Prefabricated concrete structure housing falls under the subcategory of prefabricated housing, with its core being the industrial production of building components (such as beams, slabs, walls, and columns) and their on-site assembly. The main technical types include:

• Panel-based Modular Construction: Utilizing prefabricated wall panels, floor slabs, and other components, assembled into an integral structure through connectors;
• Box-based Modular Construction: Prefabricating rooms or functional modules into 'boxes' and directly assembling them into buildings;
• Frame-based Modular Construction: Using prefabricated frames (such as beams and columns) as the skeleton, combined with prefabricated floor slabs and wall panels to form a structural system.
  The technology encompasses both prefabricated concrete structures and steel structures, with concrete structures being widely applied in residential construction due to their lower cost and strong durability.

Core Advantages

1. Shortened Construction Period: Modular construction (a more integrated prefabrication model) completes building modules in factories and assembles them on-site. For example, a public housing project in Shenzhen, Guangdong, used 6,028 concrete modules, reducing the construction period by over 60%, with the completion and delivery time shortened from 2.5-3 years to 1 year.
2. Reduced Pollution: On-site labor is reduced by approximately 50%, while also lowering noise, dust, construction waste, and traffic congestion, aligning with the trend of green building development.
3. Quality Control: Industrial production ensures component precision, reducing human errors and enhancing overall building quality.

Development History

• 1950s: China's prefabricated concrete technology began, initially applied in factory and residential construction;
• 1970s: Driven by the policy of 'three modernizations' (standardization, industrialization, and generalization) in construction, technical systems such as large-panel structures and box structures were formed;
• Mid-1980s: Stagnated due to cost and quality issues;
• 21st Century: With improved production efficiency and increased environmental demands, the technology has revived. Companies like Vanke Group have developed prefabricated shear wall residential structural systems and applied prefabricated frame technology in projects (e.g., the Nanjing Jindi Yufang project used a prestressed prefabricated concrete assembled integral frame structural system).

Overseas Market Performance

Chinese prefabricated concrete structure housing is popular in overseas markets, primarily due to its cost-effectiveness and short construction periods. According to customs data, 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%. For example, a prefabricated house costing 200,000 RMB holds a significant price advantage in the U.S. market, meeting local demands for rapid and low-cost housing.
