Yueqing Concrete Prefabricated Housing
Yueqing is involved in various aspects of concrete prefabricated housing, including the renovation of prefabricated panel houses, the production of prefabricated composite floor slabs, and the construction of concrete prefabricated component projects.
Situation of Prefabricated Panel Houses
From the 1960s to the 1990s, prefabricated panel buildings were widely constructed as an "emergency project" to address the shortage of urban housing. However, they have numerous defects. In terms of seismic performance, the simply-supported connections between the prefabricated panels and walls result in significantly lower overall integrity and seismic performance compared to current code requirements. Regarding fire resistance, many prefabricated panel buildings had limited consideration for fire protection design during construction. Some older residential communities even have situations where the installation of elevators encroaches on fire separation distances and compresses fire evacuation routes. Concerning structural aging, some old prefabricated panel houses built in the 1980s and 1990s are approaching or have exceeded their service lives. Additionally, there are behaviors such as residents privately removing load-bearing walls and illegally adding floors. In terms of living quality, there are widespread issues such as unreasonable floor plans, aging pipelines, lack of elevators, and small bathrooms. In May 2026, the State Council issued the "15th Five-Year Plan for Urban Renewal," which clearly requires establishing files and dynamically updating information on urban Class C and D dangerous housing and non-complete housing. It calls for accelerating the demolition and renovation of Class D dangerous housing. Over the next five years, more than 500,000 sets (rooms) of Class C and D dangerous housing and prefabricated panel houses in urban and county built-up areas will be renovated, basically eliminating the safety hazards of filed Class D dangerous housing. Prefabricated panel houses are not simply "demolished without further consideration" but are classified and disposed of accordingly.
Production of Prefabricated Composite Floor Slabs
Liaoning Yanshui Hydraulic Engineering Cement Products Group Co., Ltd. is a company in Yueqing related to prefabricated composite floor slabs. It is a promoter of national industrialized assembly-type building construction. It has a production base for PC prefabricated assembly-type concrete structural components, with a building area of two million square meters and an annual production capacity of 100,000 cubic meters of PC components. Its production line is a self-developed fixed-mobile combined production line, which has the advantages of high efficiency, large output, energy conservation, and environmental protection. Assembly-type buildings, represented by prefabricated PC technology, have the advantages of high quality, high speed, high efficiency, energy conservation, environmental protection, being less restricted by climatic conditions, and saving labor.
Construction of Concrete Prefabricated Component Projects
Yueqing Xingcheng Construction Co., Ltd. has a business scope that includes the construction of concrete prefabricated component projects, providing construction support for the construction of concrete prefabricated housing in Yueqing.
