Prefabricated House Production Line
The prefabricated house production line is a new construction model centered on factory-based manufacturing, achieving efficient construction through modular disassembly, intelligent production, and on-site assembly, with significant advantages such as high precision, short construction periods, and low costs.
I. Intelligent and Flexible Production Technologies
The production line employs fully automated equipment and robotic collaboration. For example, China Construction Science & Industry's steel structure modular intelligent production line spans 400 meters, with robotic completion of welding and assembly processes, maintaining a precision stability of 1-2 millimeters and achieving a daily production capacity of 50 modules, ten times the efficiency of similar factories in North America. In concrete module production, China Construction HaiLong's MiC production line overcomes flexible manufacturing challenges, producing a fully equipped module every 20 minutes with an annual delivery capacity of 20,000 to 30,000 units. Wall panel installation robots can complete skim coating for 70 square meters of wall surface in 20 minutes, far surpassing traditional manual efficiency.
II. Parallel Operations and Digital Management Systems
Through modular disassembly, multiple processes are carried out in parallel. For instance, a house is decomposed into six surfaces—bottom, top, and sides—manufactured simultaneously on sub-production lines before being assembled into a box unit, significantly shortening construction periods. Each module is equipped with a unique QR code 'identity card' for traceability of all production data. Hidden engineering inspection robots utilize laser scanning for 3D reconstruction, automatically comparing with design drawings to intercept millimeter-level errors and ensure quality control.
III. Leading Enterprises and Market Applications
China Construction HaiLong's vertical factory connects 190 workstations and over 80 pieces of equipment into a 'house production line,' enabling direct output from sand and gravel feeding to finished modules. CIMC has independently developed a steel structure integrated modular system covering high-end office buildings, hotels, and other categories, with a market presence in over 20 countries and regions and an average annual output value of 77.458 million yuan. A social housing project in Shenzhen, Guangdong, utilized 6,028 concrete modules for assembly, reducing the construction period from 2.5-3 years to 1 year, cutting on-site labor by approximately 50%, and significantly reducing noise and dust pollution.
IV. Global Market Recognition and Export Advantages
Chinese prefabricated house modules have been exported to markets such as Australia, the UK, and ASEAN, with export growth reaching 45% in the first quarter of 2026 and high repurchase rates from overseas clients. For example, the owner of a hotel project in Papua New Guinea continuously increased orders to the fifth phase, demonstrating technological maturity and market competitiveness.
