Zhangye Prefabricated Assembled Housing

Zhangye has witnessed rapid development in the field of prefabricated assembled housing, with significant policy support, remarkable project progress, stringent supplier requirements, and unique advantages reflected in its scientific principles.

Policy Support Sets Clear Goals

In 2017, the Office of the Zhangye Municipal People's Government issued an implementation plan to promote the development of prefabricated buildings, setting phased goals. By 2020, a number of pilot projects were to be completed, initially forming an industrial chain; by 2025, the proportion of prefabricated buildings in newly constructed buildings across the city was to reach 30%. The plan also clarified promotion tasks, including project support and the cultivation of leading enterprises, providing policy guidance and direction for the development of prefabricated housing.

Project Progress Yields Fruitful Results

In 2026, a report from the Gansu Provincial Department of Housing and Urban-Rural Development showed that Zhangye City led the five cities in the Hexi region with a growth rate of 42.1%. In Ganzhou, Linze, and Gaotai, 17 prefabricated projects were under construction, with 9 adopting the EPC (Engineering, Procurement, and Construction) general contracting model and the prefabrication rate of the main structure not less than 50%. Among them, Zhangye **** Experimental Middle School explicitly adopted an assembled monolithic concrete frame structure, with the application rate of prefabricated composite floor slabs exceeding 65%; the BIM (Building Information Modeling) collaboration platform of Zhangye **** Hospital had been integrated into the regulatory system. Additionally, the prefabricated movable, multifunctional, and intelligent housing construction project of Gansu Yuncheng Youyi Future Intelligent Manufacturing Technology Co., Ltd. had also received relevant planning permission announcements.

Supplier Requirements Are Stringent and Standardized

Since 2026, among the landed prefabricated projects, 83% have required suppliers to provide performance proofs of similar projects in the past three years, with at least one project located in the cold northwest region; 76% have explicitly required certification as a prefabricated building industrial base at the provincial level or above; all bid projects have listed 'factory production + on-site hoisting integrated service capability' as a disqualifying criterion for qualification review. For example, the affordable housing project in Linze County required bidders to provide the coordinates and annual production capacity proof of their own or long-term cooperating PC (precast concrete) component production bases, with a straight-line distance from Zhangye City not exceeding 300 kilometers.

Scientific Secrets Highlight Advantages

The core of prefabricated buildings lies in the in-depth decoupling and recoupling of building material properties. Taking color-steel sandwich panels as an example, the surface metal sheet and the internal core material are compounded into a whole unit in the factory, forming a new performance composite. The assembly of prefabricated units involves the phenomenon of 'system emergence,' where the design of standardized connection nodes determines the emergent properties of the overall structure, which dynamically interacts with the external environmental energy flow, reducing the building's active energy consumption and providing a physical model for life-cycle energy consumption management.
