Rizhao Prefabricated House Construction
Rizhao has developed a mature model of coordinated development in technology, market, and policy for prefabricated house construction, with specific progress as follows:
I. Export Model Upgrade and Market Expansion
The Rizhao Green Prefabricated Building Industrial Park has achieved breakthroughs through the 'independent overseas expansion' model. In February 2026, the park undertook a 2,400-square-meter customized packaged housing project in Sierra Leone, completing the entire process from design and cost estimation to container loading and customs declaration independently, with the construction period shortened to within two months. Compared to the traditional 'hitching a ride overseas' model, independent overseas expansion not only increases profit margins but also enhances technological influence by optimizing steel structure solutions. Additionally, Rizhao enterprises have successfully exported prefabricated houses to the extremely cold regions of Russia, developing insulation and structural safety technologies to address challenges posed by -35℃ extreme cold and permafrost, gaining international market recognition and marking their technological adaptability covering diverse global climate zones.
II. Policy Regulation and Standardization Construction
The 'Technical Guidelines for the Construction of Prefabricated Rural Houses' issued by Shandong Province provides institutional guarantees for the development of prefabricated houses in Rizhao. The guidelines explicitly require that prefabricated rural houses should be constructed using factory-prefabricated or partially prefabricated components assembled on-site, with detailed regulations established for key aspects such as structural systems, materials, and design. For example, they stipulate that steel-structured rural houses must meet seismic fortification requirements, and concrete components must have a positional accuracy error of no more than 3 millimeters for reserved embedded parts. At the same time, the guidelines emphasize respecting farmers' housing needs, requiring architectural styles to reflect regional characteristics, such as incorporating traditional elements like pitched roofs and gray brick tiles in southeastern Shandong to avoid a 'one-size-fits-all' appearance.
III. Transparent House Construction and Quality Control
Shanhai Elephant Group has established the country's first full-scenario transparent factory in Rizhao, achieving full-process visualization of house construction through a system of '1 major archive + 3 major commitments + 6 major transparencies + 10 major experiences + 12 major health technologies'. Homebuyers can view archive materials such as building material inspection reports and construction process standards in real-time, and enjoy commitments like 'lifetime warranty for the main structure' and 'unconditional refund for non-compliant environmental standards'. The factory uses BIM technology to simulate the construction process, identifying issues like pipeline collisions in advance to reduce rework rates; it also introduces an air quality monitoring system to ensure indoor concentrations of pollutants such as formaldehyde and TVOC are more than 50% below national standards, effectively eliminating consumer concerns about quality and health.
