1. Suzhou implements "double code traceability" supervision of prefabricated components
From January 1, 2025, Suzhou will implement full-process information collection for prefabricated concrete components (composite floor slabs, wall panels, stairs, etc.) of new housing projects. Production enterprises need to register on the municipal prefabricated building management platform to generate "first-level code" (enterprise qualification) and "second-level code" (batch tracking). The supervision unit verifies the quality documents by scanning the code, and unqualified components are prohibited from use, and blockchain technology is used to ensure that the data cannot be tampered with. This move aims to strengthen quality traceability and has promoted more than 20 leading companies in the Yangtze River Delta region to complete system docking.
2. Jiaxing Forum releases intelligent transformation roadmap
On March 22, the 14th China (International) Precast Concrete Technology Forum was held in Jiaxing, and more than 300 experts discussed the theme of "Intelligent Manufacturing". The meeting disclosed:
Breakthrough in hydrogen energy equipment: Sany Heavy Industry's first hydrogen energy concrete pump truck completed road testing and will be mass-produced in 2026;
Deepening international cooperation: Jiaxing, Shanghai and Hangzhou jointly built a precast concrete intelligent manufacturing demonstration base, introduced German automated production line technology, and shortened the production cycle by 30%;
Wind power component upgrade: Beijing Yugou achieved wind power tower accuracy error ≤2mm, and the product was applied to coastal wind power projects.
3. Carbon footprint standards trigger industrial chain reconstruction
The "Quantification Method and Requirements for Carbon Footprint of Greenhouse Gas Products" of the China Building Energy Conservation Association was enforced on May 1, requiring companies to record carbon emissions from raw material mining to transportation through blockchain. The pilot showed:
The Xiongan New Area affordable housing project uses CO₂ injection technology, and the carbon emissions of a single component are reduced by 12%;
The photovoltaic power supply production line of Jiangsu Subote Company has reduced the carbon emissions of the laminated board to 65% of the industry average, thereby winning a 580 million yuan order for the second phase of the Jakarta-Bandung High-speed Railway in Indonesia.
4. Prestressed prefabricated national standard implements earthquake resistance upgrade
The Ministry of Housing and Urban-Rural Development approved the "Technical Standard for Prestressed Prefabricated Concrete Frame Structure" (JGJ/T 499-2025), which will be implemented from April 1. The new standard clearly states for the first time:
Class III prestressed frames can be used in 9-degree earthquake resistance zones;
Requires the design stage to include limit state verification such as earthquakes and accidental disasters, and promotes the technical innovation of node connection in high-rise buildings. China Construction Technology applied this system in the Zhuhai super-high-rise project, shortening the construction period by 25%.
5. Overcapacity in the Yangtze River Delta forces specialization transformation
Data from the Hangzhou Association shows that the local concrete component capacity utilization rate was only 50% in the second quarter of 2025, and the spare capacity reached 361,000 cubic meters. Enterprise response strategies include:
Turning to new energy infrastructure: Fujian manufacturers will convert 30% of their production capacity to offshore wind power piles, and the gross profit margin will increase by 8 percentage points;
Scaled solid waste recycling: Chengdu has put into operation an intelligent sorting line for construction waste, processing 50 tons per hour, and the cost of recycled aggregate curbstones has dropped by 18%, which will be promoted to 20 "zero-waste cities" within the year.
6. International projects drive overseas localized production
In the first four months, my country's component exports increased by 42% year-on-year, and enterprises accelerated their overseas layout:
Saudi Arabia modular project: Beijing Prefabricated Building Engineering Research Institute provided technical consultation for Saudi Arabia residential projects, adopting 3D design-domestic prefabrication-on-site assembly mode, reducing logistics costs by 40%;
Thailand production base: Sany Construction Thailand Rayong Factory was put into production, supplying 32,000 cubic meters of residential components for Hanoi Smart New City in Vietnam, achieving "72 hours factory, 15 days assembly".
Focus on industry challenges:
Transportation radius bottleneck: Shandong piloted "regional shared factory", deployed satellite factories in a 300-kilometer radiation circle, and reduced cross-provincial freight by 35%;
Skilled worker shortage intensified: The turnover rate of mold technicians in South China was 27%, and the welding robot transformation rate increased by 60% year-on-year.
