Prefabricated House Processing
Prefabricated house processing is a construction model that involves producing building components through industrial methods and assembling them on the construction site.
Production Model: The entire building is broken down into independent modules. The manufacturing of each component is completed in the factory, and then they are transported to the construction site for assembly. For example, at the China Construction Hailong Intelligent Construction Industrial Park in Shenzhen, Guangdong, the ceilings, walls, and waterproof layers of bathrooms in houses are all made in the factory. Scattered components are first produced separately on different floors and then sent to the final assembly station for complete assembly.
Production Process: Taking the intelligent factory workshop for steel-structure modular products of China Construction Science and Industry Corporation as an example, a house is divided into six surfaces (bottom, top, and four sides), which are produced in parallel on six sub-production lines and finally assembled into a complete box at the end. The country's first steel-structure modular intelligent production line, over 400 meters long, operates around the clock. Robots and AGVs (Automated Guided Vehicles) work in tandem. Through laser cutting and welding, each steel bar and connection point follows digital instructions executed by robots with millimeter-level precision stability. It can produce 50 modules per day, ten times the output of similar factories in North America.
Technical System: It covers prefabricated concrete structures and steel structures, with components including prefabricated products such as beams, slabs, walls, and columns. For instance, the Nanjing Jindi Yufang project adopted a prestressed prefabricated concrete assembled integral frame structural system.
Advantages and Characteristics: Short construction period, with over 70% of the processes shifted to the factory, reducing the construction cycle by more than 60%; controllable quality, as each component has a detailed 'ID card' with precise positioning of steel bars; energy-saving and environmentally friendly, reducing noise, dust, construction waste, and traffic congestion at the construction site; easy to maintain, with more detailed design and relatively flexible repairs.
Application Scenarios: It can be applied to various building types such as hotels, apartments, hospitals, and residential buildings. Chinese-made prefabricated houses are also popular overseas. According to customs data, in the first four months of 2026, the Guangzhou Customs District exported movable houses worth 1.4 billion yuan, a year-on-year increase of 38.1%.
