Reinforced Concrete Prefabricated House

Reinforced concrete prefabricated houses are a type of prefabricated assembled building, produced industrially and assembled on-site, offering advantages such as efficiency, environmental protection, and earthquake resistance.

Structural Types and Construction Methods

The load-bearing components (such as columns, beams, and slabs) of reinforced concrete prefabricated houses are made from a composite of steel reinforcement and concrete, utilizing the tensile strength of steel and the compressive strength of concrete to form a strong and resilient structural system. There are two main construction methods:

1. Prefabricated Assembly: Components are standardized and produced in factories, then transported to the site for direct assembly using bolts, welding, or other methods, ensuring fast construction and high precision.
2. Assembled Monolithic Construction: Some components (such as floor slabs) are cast with concrete on-site, integrating with prefabricated components to balance efficiency and structural stability.

Technical Advantages

1. High Construction Efficiency: Prefabricated components can be mass-produced, significantly reducing on-site assembly time. For example, a villa was completed in just 4 hours in a rural area of Henan, with a unit price of approximately 300 yuan per square meter.
2. Outstanding Environmental Performance: Factory production reduces on-site wet operations, cutting construction waste by over 70%. Regions like Fujian have established industrial bases through policy support to promote green construction.
3. Strong Earthquake Resistance: The integrated structure ensures good overall performance, with steel and concrete working together to effectively dissipate seismic energy. For instance, 171 prefabricated houses rebuilt after the 2026 disaster in Xialasu Village, Tibet, are designed to withstand an 8-magnitude earthquake.

Application Scenarios and Design Features

1. Wide Applicability: Suitable for high-rise residential buildings, large public structures (such as hospitals and schools), and industrial plants, with modular construction further enhancing efficiency.
2. Durability and Fire Resistance: Concrete cover and steel corrosion-resistant coatings extend the structural lifespan, while the high heat capacity of concrete improves fire resistance.
3. Design Flexibility: The plasticity of fresh concrete allows for the production of irregular components, meeting diverse architectural needs such as curved walls and complex joints.

Market Development

China's prefabricated housing technology is mature and in high demand overseas. In the first four months of 2026, the export value of movable houses from the Guangzhou Customs district reached 1.4 billion yuan, a year-on-year increase of 38.1%, primarily to Southeast Asia and the Middle East. This trend reflects the comprehensive competitiveness of prefabricated houses in terms of cost, efficiency, and environmental protection.
