Shanghai Prefabricated Houses and PC Prefabricated Components
Shanghai has developed a mature ecosystem in the field of prefabricated houses and PC prefabricated components, forming a complete system from technical standards to practical applications.
Practice and Development of Prefabricated Houses
Shanghai took an early lead in the prefabricated housing sector, driven by corporate practice and technological innovation. Shanghai Construction Group leveraged its advantages across the entire industrial chain to lead the first steel-structured residential prefabricated building project—Haiyue Xuandi Building 4 in the Xuanqiao 05-02 plot in the Pudong New Area, achieving full autonomy from investment and development to construction. Additionally, Shanghai Construction Real Estate has continuously explored in the prefabricated building sector, such as the collaboration with Vanke in 2007 on two 14-story prefabricated residential buildings in Shanghai Vanke Xinlicheng, which became one of the first pilot projects for industrialized housing in China, marking the transition of prefabricated technology from experimentation to large-scale application. These projects not only validated the feasibility of prefabricated buildings in high-rise residential settings but also provided data support for subsequent technological optimizations.
Industrial Layout of PC Prefabricated Components
The PC prefabricated component industry in Shanghai is characterized by scale and diversification. Manufacturers are concentrated, covering multiple districts such as Yangpu, Jing'an, and Pudong New Area, offering a variety of product types including PC components, ALC panels, aerated concrete blocks, etc., to meet different construction needs. For example, PC components can be further divided into housing prefabricated components, PC composite slabs, prefabricated cast-in-place beams, etc., widely used in residential, commercial, and municipal projects. In terms of technological upgrades, Shanghai Construction Materials Engineering Co., Ltd. has promoted green industrialized production by researching and developing production technologies and process equipment for prefabricated components, reducing energy consumption and pollution from on-site construction. Furthermore, PC component manufacturers in Shanghai have formed synergies with local construction companies, such as providing customized components for prefabricated housing projects, shortening construction cycles and improving project quality.
Technical Standards and Policy Support
Shanghai has provided unified technical specifications for the industry by formulating the Calculation Rules for the Prefabrication Rate and Assembly Rate of Individual Prefabricated Buildings. These rules clarify the calculation methods for the prefabrication rate (the proportion of prefabricated component volume to total concrete volume) and the assembly rate (the proportion of prefabricated component assembly joint numbers), and set application scopes for different structural types (such as steel structures and concrete structures). This policy not only regulates market behavior but also guides companies in optimizing design schemes through quantitative indicators, such as reducing on-site wet operations by increasing the prefabrication rate or improving construction efficiency through modular design.
In conclusion, Shanghai has formed a development pattern of corporate practice leading, complete industrial support, and sound policy standards in the field of prefabricated houses and PC prefabricated components, providing replicable experience for the promotion of prefabricated buildings nationwide.
