New Type Prefabricated House Components

New type prefabricated house components are industrialized building elements that enable rapid construction through on-site assembly. They cover both concrete and steel structures, including beams, slabs, walls, columns, and other types, offering advantages such as shortened construction periods, environmental protection, energy efficiency, and controllable quality.

Core Types and Technical Characteristics

1. Modular Construction: Buildings are divided into independent modules, with all manufacturing of ceilings, floors, plumbing, and electrical systems completed in factories, followed by direct on-site assembly. For example, a public housing project in Shenzhen, Guangdong, utilized 6,028 concrete modules, reducing the construction period from 2.5-3 years to just 1 year, cutting on-site labor by approximately 50%, and reducing noise and dust pollution. This model relies on technological systems, production systems, and industrial clusters for support, with the global market size expected to exceed $142.8 billion by 2030.
2. Panel-Based Prefabrication: Utilizing prefabricated wall panels and floor slabs as core components, this approach expands indoor usable space but has limited design flexibility, making it suitable for projects with high standardization requirements.
3. Box-Based Prefabrication: By combining prefabricated functional units (such as bathrooms and kitchens), construction speed can be increased by 50%-70%. However, this method requires higher transportation and lifting equipment capabilities, making it suitable for projects with clear spatial functional divisions.
4. Frame-Based Prefabrication: This approach employs prestressed prefabricated concrete assembled integral frame structures, such as the Nanjing Jindi Yufang project, which combines structural strength with construction efficiency through factory-prefabricated frame components assembled on-site.

Application Advantages

• Significantly Shortened Construction Periods: Modular construction reduces construction periods by over 60% compared to traditional methods, with the main structure of a fully prefabricated residence in Zhejiang assembled in just 7 days.
• Outstanding Environmental Protection and Energy Efficiency: Fujian Province has established industrial bases with policy support, achieving over 70% reduction in construction waste and lowering construction energy consumption.
• Precise Quality Control: Each prefabricated component is labeled with an 'ID card' (including project name, model, and production date), with errors controlled to the millimeter level, reducing human construction errors.

Market and Price Trends

China's export of prefabricated houses has grown significantly, with Guangzhou Customs reporting exports of movable houses worth 1.4 billion yuan in the first four months of 2026, a year-on-year increase of 38.1%. Prices vary greatly by type: reinforced concrete prefabricated house modular structures sell for approximately 450 yuan per unit, while grouting mesh wall construction equipment is priced at 168,000 yuan per set, reflecting the impact of technological complexity and material costs on pricing.
