Dandong Prefabricated Assembly-Type Housing

Dandong's prefabricated assembly-type housing has developed rapidly, with widespread market applications driven by policies, diverse technical forms, and clear procurement strategies.

Policies and Market: Mainly focused on affordable housing and public buildings
Dandong City has actively responded to national and Liaoning Province policies, with newly started construction of prefabricated buildings covering an area of 873,000 square meters in the first quarter of 2026, a year-on-year increase of 21.6%, accounting for more than 34% of the total area of newly built buildings. Under rigid policy constraints, the market has formed four main application lines centered around affordable housing, schools, hospitals, and supporting buildings in industrial parks. For example, a certain center project in Dandong has an assembly rate of ≥50% for its main structure, a school project adopts an "integrated prefabricated frame + steel structure roof" system, and a hospital's medical complex building project has initiated bidding for a prefabricated interior decoration system, all reflecting diversified application scenarios under policy guidance.

Project Dynamics: Short cycle and centralized decision-making
As of April 2026, there are 42 prefabricated projects in Dandong City in the stages of construction preparation and bidding, of which 19 have issued procurement notices or entered the prequalification stage. The average project cycle has been shortened to 5.8 months, featuring characteristics of "fast pace, short window, and centralized decision-making chain." Typical projects have clear requirements, such as a center project needing to purchase composite floor slabs, ALC wall panels, and integrated bathroom modules; a school project requiring technical parameters of prefabricated stairs and balcony slabs to comply with local standards JGJ1-2014 and DB21/T3572-2022; and a hospital project requiring suppliers to have experience in similar medical projects, highlighting technical specifications and experience thresholds.

Technical Forms: Differentiated designs adapted to the climate
Prefabricated assembly-type housing in Dandong is mainly composed of knock-down container houses and panel prefabricated temporary buildings. The former uses standard containers as modules, combined through professional connection technologies, featuring modularity, short construction periods, flexible mobility, and sturdy structures. However, they require enhanced insulation, moisture-proofing, and heat insulation treatments to adapt to the coastal humid climate. The latter adopts light steel structures and sandwich panel prefabricated components for rapid on-site assembly, with advantages including fast construction speed, cost-effectiveness, and good environmental performance. However, they require attention to wind and moisture-proof designs and are suitable for multiple scenarios such as temporary dormitories, agricultural warehouses, and commercial shops.

Procurement Strategies: Focus on windows and nodes
Over 73% of the procurement demands for prefabricated building materials are released on the Liaoning Government Procurement Website 30-45 days in advance and can be filtered by region and category through the Zhongxiangcai database. The turnover rate of procurement leaders reached 38% from January to April 2026, necessitating timely follow-up on key nodes after the completion of construction drawing reviews to ensure information synchronization and decision-making efficiency.
