Prefabricated Panel Houses in Xiaogan, Hubei

Prefabricated panel houses in Xiaogan, Hubei, are constructed primarily using prefabricated panels. They offer advantages such as short construction periods and energy efficiency, but they also have drawbacks like weak earthquake resistance and poor sound and thermal insulation. Currently, the policy focuses on repair and renovation.

Definition and Characteristics of Prefabricated Panel Houses

Prefabricated panel houses utilize factory-made cement components (prefabricated panels) as the main load-bearing or enclosure structures, available in solid and hollow types. Hollow panels achieve lightweighting by reducing non-load-bearing concrete, but due to their poor earthquake resistance, they are no longer recommended for building structures. Modern construction often employs cast-in-place structures to enhance overall integrity. Three common issues with existing prefabricated panel houses are:

1. Weak Earthquake Resistance: The low strength of connection nodes between prefabricated panels makes them prone to misalignment or collapse during earthquakes.
2. Poor Sound and Thermal Insulation: Hollow structures or thin panel designs result in insufficient sound insulation and thermal insulation performance.
3. Limited Service Life: With a designed lifespan of approximately 30-50 years, there is an increased risk of structural aging after long-term use.

Prefabricated Panel-Related Enterprises and Products in Xiaogan

1. Wuhan Zimuzi Building Materials Co., Ltd.: Offers bearing platform prefabricated hollow panels with characteristics such as easy cutting, high strength, and corrosion resistance. Prices start at 30 yuan per square meter, suitable for foundation construction and other scenarios.
2. Hubei Xinheng Integrated Housing Co., Ltd.: Specializes in the assembly, sales, and leasing of prefabricated buildings (mobile houses), as well as the production of steel structure products. In 2024, the company added the "Construction of a Production Base for 5,000 Sets of Green Energy-Saving Integrated Houses and New Energy-Saving Wall Panels per Year" project to drive industrial upgrading.

New Prefabricated Building Form: Box-Type Houses

The box-type houses promoted in Xiaogan feature standardized steel structure boxes. The main structure, walls, water and electricity pipelines, etc., are prefabricated in the factory and quickly assembled on-site. Their advantages include:

• Short Construction Period: Reduced by more than 60% compared to traditional methods.
• High Material Recycling Rate: Aligns with green building concepts.
• Flexibility: Can be expanded, relocated, or reassembled to meet temporary or long-term usage needs.

Policy and Market Dynamics

Since 2022, China has implemented renovation policies focusing on repair and renovation of prefabricated panel houses, with demolition only for buildings that meet hazardous building standards. In the first four months of 2026, exports of mobile houses from Guangzhou, Shenzhen, and other regions increased significantly, reflecting the growing market demand for prefabricated buildings. Enterprises in Xiaogan may benefit from this trend.
