Guangdong Concrete Prefabricated Houses
Guangdong has established a mature system for the coordinated development of technology, industry, policy, and market in the field of concrete prefabricated houses (prefabricated buildings), leading the nation.
I. Technological Innovation Drives Industry Upgrading
Eight prefabricated building technologies from Guangdong Province have been included in the first batch of replicable and scalable technologies promoted nationwide, covering two major directions: structural systems and modular technologies. For example, China Construction Science & Technology's "prefabricated double-sided wall panel composite shear wall structure" enhances construction efficiency through standardized components; Guangzhou Construction's "MIC fully prefabricated concrete modular building" technology achieves full professional integration in construction, with an assembly rate exceeding 90% and a construction period shortened by 50%-70%. Additionally, the "prefabricated prestressed double-T slab" developed by Shenzhen Special Zone Construction Engineering Group breaks through the bottleneck of long-line production technology, supporting large column spacing designs, increasing building space utilization by 15%-20%, and reducing material waste costs by approximately 10%.
II. Policy Support Builds a Whole-Industry-Chain Ecosystem
At the provincial level, multiple special policies have been introduced, with 21 cities issuing implementation opinions and 17 cities formulating special plans, creating a full-chain support system covering planning, land use, and finance and taxation. The province has established 17 prefabricated building component production bases, covering all aspects of design, production, and construction, forming a large-scale industrial cluster. For example, Guangzhou has strengthened production quality supervision through the "Regulations on the Management of Ready-Mixed Concrete, Ready-Mixed Mortar, and Concrete Prefabricated Components," increasing the standardization rate of components to over 85% and providing guarantees for market applications.
III. Dual Growth in Market Application and Export
Prefabricated technologies in Guangdong Province have been widely applied in areas such as affordable housing and commercial complexes. Projects like Phase III of Shenzhen CR Land Runfu and Zhanjiang Dongsheng Road Public Rental Housing all adopt prefabricated concrete structures, achieving green construction and cost optimization. Meanwhile, the export scale of Chinese prefabricated houses continues to expand. In the first four months of 2026, the export value of movable houses in the Guangzhou Customs area reached 1.4 billion yuan, a year-on-year increase of 38.1%, mainly exported to Southeast Asia, the Middle East, and other regions, demonstrating international competitiveness.
IV. Diversified Development of Technological Systems
Prefabricated buildings in Guangdong cover three major structural types: panel, box, and frame, with technological paths including both concrete and steel structures running in parallel. Component types cover all categories such as beams, slabs, walls, and columns. Among them, modular buildings combine factory prefabrication with on-site assembly, increasing construction speed by 50%-70% compared to traditional methods and reducing construction waste emissions by approximately 60%, aligning with low-carbon development needs.
