Prefabricated House Assembly in Guangdong

Prefabricated house assembly in Guangdong primarily adopts a modular construction model, achieving efficient construction through a combination of factory prefabrication and on-site assembly, forming a coordinated development system of technology, industry, and export.

Technical Model and Core Advantages

Prefabricated house assembly in Guangdong centers on modular construction, breaking down buildings into independent unit modules. These modules undergo standardized design and centralized production in factories before being transported to the site for assembly, creating a construction model akin to “manufacturing parts in a factory and assembling them like building blocks on-site.” Its advantages are significant:

1. Short Construction Period: Over 70% of the processes are completed in the factory, reducing the overall construction period by more than 50%. For example, the four-story police station office building in Huadu District, Guangzhou, took less than a month from module hoisting to delivery.
2. Controllable Quality: The stable factory environment ensures high standardization in material processing and dimensional control, avoiding weather interference and achieving far superior quality stability compared to on-site construction.
3. Environmental Protection and Energy Efficiency: Solid waste emissions throughout the lifecycle are reduced by 75%, on-site workforce by 70%, and dust and noise pollution are significantly decreased.
4. Strong Adaptability: Customized solutions can be tailored to the climate, structural, and utility requirements of different countries and regions, covering diverse scenarios such as high-end office buildings, hotels, and schools.

Industrial Application and Export Performance

Prefabricated construction in Guangdong has achieved large-scale application and international expansion:

• Domestic Application: Multiple projects have been implemented in Guangzhou, Dongguan, and other locations. For instance, CIMC Modular Building Systems Co., Ltd. in Guangdong has developed an integrated steel structure modular system, with products covering the domestic high-end construction market.
• International Export: In the first seven months of 2026, Huangpu Customs supervised the export of 23 batches of modular houses with a value of 548 million yuan, a 7.3-fold increase year-on-year; nationwide, enterprises exported portable houses worth 1.68 billion yuan through Shenzhen ports, a 19.6% increase year-on-year, with products sold to over 150 countries and regions. CIMC Modular Building Systems delivered modular buildings worth 59.772 million yuan in the first half of the year, exporting to Cameroon, Indonesia, Australia, the UK, and other locations.

Policy Support and Challenge Response

To promote industrial development, Guangdong Customs and local governments have collaborated to optimize regulatory processes:

• Customs Optimization: Shatian Customs expanded the scope of “water-to-water transfer” routes, while Xinhui Customs guided enterprises in upgrading their account modes, reducing logistics and compliance costs.
• Technical Standards: Guangzhou released the nation's first unified technical system for modular construction, categorizing it into four major types and verifying the seismic performance of the “composite concrete system,” providing a normative basis for the industry.

Challenges and Recommendations:

• Challenges: Significant differences in building codes across countries, high certification costs, and complex customs clearance processes for concrete and steel-concrete modules.
• Recommendations: Leverage digital platforms to embed multi-standard adaptability capabilities and promote the alignment of Chinese standards with international norms; establish an overseas certification resource-sharing platform to reduce compliance costs for enterprises.
