Nanchang Prefabricated Concrete Houses

Nanchang has made remarkable progress in the field of prefabricated concrete houses (prefabricated buildings), forming a certain industrial scale and achieving widespread application.

I. Major Production Enterprises and Production Capacity

Nanchang Municipal Yuanda Construction Industry Co., Ltd., established in May 2016, is one of the early local enterprises to deploy in the production of prefabricated concrete components. Its production scope covers core components such as interior wall panels, shear wall panels, and composite floor slabs. These components are key parts of prefabricated buildings and are transported to construction sites for assembly after standardized factory production, significantly improving construction efficiency and quality stability.

Jiangxi Construction Engineering Prefabricated Building Co., Ltd., founded in August 2018, focuses on the research and development and production of concrete prefabricated parts. Its product system is more diverse, including not only conventional components but also special components such as integrated utility tunnels and composite insulated exterior wall panels. The annual production capacity of the company's first-phase industrial base reaches 150,000 cubic meters. Calculated based on the density of conventional building components, it can meet the demand for approximately 1.5 million square meters of prefabricated buildings, providing important production capacity support for Nanchang and its surrounding areas.

II. Policy Promotion and Market Application

Nanchang has mandated the development of prefabricated buildings through policies, explicitly requiring that 100% of newly started housing construction projects invested by the government adopt prefabricated technology. This measure has directly driven market demand, prompting enterprises to expand production capacity and optimize technology. Currently, the proportion of prefabricated building area in Nanchang has reached 30%, with application scenarios covering factory buildings, office buildings, and residential communities. For example, some newly built residential communities adopt a combination of composite floor slabs and prefabricated exterior wall panels for construction, shortening the construction period and reducing on-site wet operations, in line with the development trend of green buildings.

III. Technological Advantages and Industry Impact

The factory production of prefabricated concrete components achieves standardization and modularization. By using precise molds and automated equipment to control component dimensions, on-site construction errors are reduced. Meanwhile, components complete processes such as steel bar binding, concrete pouring, and curing in the factory, with quality stability superior to traditional cast-in-place processes. In addition, prefabricated construction can significantly reduce construction waste and dust pollution, aligning with the transformation needs of the construction industry under the "dual carbon" goals. Nanchang's industrial practice provides a replicable model for the development of prefabricated buildings in the central region and promotes the industrialization of construction.
