Prefabricated Housing Components in Jiangsu
Jiangsu has made remarkable progress in the prefabrication of housing components in terms of policy support, technological standards, industrial scale, corporate practices, and market applications.
Policy Support and System Improvement: The Jiangsu provincial government places great emphasis on the development of prefabricated buildings. By issuing policy documents such as the Opinions on Accelerating the Modernization of the Construction Industry and Promoting its Transformation and Upgrading, it has clarified the direction for the transformation and upgrading of the construction industry. The comprehensive promotion of prefabricated interior and exterior wall panels, stair treads, and floor slabs, known as the 'three panels,' provides policy guarantees for increasing the prefabrication rate of newly constructed buildings.
Technological Standards and Achievements: Jiangsu continuously improves its technological standard system for prefabricated buildings, having formulated and issued 25 local standards and 11 standard designs, promoting the application of typical systems such as the integral prefabricated shear wall structural system. Relevant research achievements won two first prizes in the Jiangsu Provincial Science and Technology Awards in 2017, demonstrating the leading edge of technological innovation.
Industrial Scale and Demonstration Creation: As of the end of 2023, the cumulative newly started prefabricated building area in Jiangsu has reached approximately 250 million square meters, with the proportion of newly started prefabricated building area increasing from 3% in 2015 to 41.0% of the total newly started building area in the same period. Additionally, Jiangsu has created 5 national-level demonstration cities for prefabricated buildings, 27 industrial bases (parks), as well as 21 provincial-level demonstration cities (parks), 252 demonstration bases, and 311 demonstration projects, forming a large-scale development pattern.
Corporate Practices and Innovation: Jiangsu GeGou Prefabricated Housing Component Co., Ltd. produces PC components, self-insulating wall panels, and other products with advantages such as high crack resistance and short construction periods. Jiangsu Huada Prefabricated Housing Co., Ltd. covers design, manufacturing, and general contracting services, participating in projects such as the archaeological protection of the Sidun Site. The BanDa Space Integrated Housing Team adopts lightweight aggregate concrete prefabricated buildings, achieving 90% factory finishing and delivering fully furnished houses within 7 days, showcasing an efficient and environmentally friendly innovation model.
Market Applications and Prospects: Prefabricated buildings are widely welcomed in the Jiangsu market due to their high efficiency, standardization, good quality, and strong environmental protection. Market research institutions predict that by 2030, the global modular building market size will exceed USD 142.8 billion. With a complete industrial chain (design and R&D, intelligent production, logistics, and installation), China possesses core competitiveness, and Jiangsu, as a pioneering region, has enormous development potential.
