Prefabricated House Assembly in Zhongshan, Guangdong

Zhongshan in Guangdong has developed a mature technical system in the field of prefabricated house assembly, with prefabricated buildings and container houses as the core application directions, driving the construction industry towards efficiency and standardization.

Prefabricated Buildings: Combining Standardized Design with Industrial Production

The prefabricated buildings in Zhongshan are exemplified by the Vanke Central Park project. Among the 14 towers in this project, the 2nd floor and above utilize four types of prefabricated components: prefabricated concrete floor slabs (including roof slabs and balcony slabs), formwork-free templates, ceramsite concrete hollow slabs, and prefabricated stairs. The assembly rate reaches 50.2%, meeting the basic-level standard. Its core advantages include:

• Efficiency Improvement: By combining factory prefabrication with on-site assembly, the construction period is shortened by six months compared to traditional methods, significantly enhancing project efficiency.
• Quality Optimization: Standardized design reduces construction errors, and the industrial production of prefabricated components ensures the stability of material properties. For example, the dimensional accuracy of prefabricated stairs can be controlled within millimeters, avoiding honeycombing and pitting issues common in on-site pouring.
• Policy Support: The Zhongshan Housing and Urban-Rural Development Bureau has issued notices encouraging applications for prefabricated building industrial bases and demonstration projects in 2024. Through financial subsidies and technical guidance, it promotes enterprise participation, forming a collaborative development model across the entire "design-production-construction" industrial chain.

Container Houses: Balancing Modularity and Flexibility

Container houses in the Zhongshan market are centered around modular design, covering types such as residential prefabricated houses, movable panel houses, and quick-assembly mobile houses, with price ranges from 299 yuan to 8,000 yuan, meeting diverse scenario demands:

• Application Scenarios: In scenarios like temporary housing on construction sites, offices, and homestays, container houses can be quickly assembled and disassembled, offering easy mobility. For example, a construction site project used quick-assembly mobile houses as employee dormitories, completing the setup of 20 rooms within three days, improving efficiency by 50% compared to traditional panel houses.
• Technical Features: They adopt high-strength steel frames and fire-resistant and heat-insulating materials, meeting national safety standards. Modules are connected via bolts, eliminating the need for welding and reducing construction difficulty. Some products integrate water and electricity systems, enabling "move-in readiness."

Conclusion: Through the dual paths of prefabricated buildings and container houses, Zhongshan has constructed a prefabricated assembly technical system ranging from high-rise residential buildings to temporary structures. Driven by both policy guidance and market demand, prefabricated assembly technology is becoming a key pillar for the transformation and upgrading of Zhongshan's construction industry.
