Full Process of Prefabricated House Construction

The entire process of prefabricated house construction typically includes core steps such as custom production, transportation, overseas shipping, and assembly, with some local variations depending on the type of house. The specific process is as follows:

1. Custom Production and Modular Packaging
Taking modular prefabricated houses as an example, factories customize the layout, style, and functionality according to customer needs, producing standardized modules in batches. All modules are uniformly coded, classified, and inspected, and undergo waterproofing, anti-corrosion, and anti-seismic treatments to ensure compatibility with ocean shipping environments. The production process covers steel structure main body welding, wall installation, pre-embedding of water and electricity pipelines, door and window installation, and full-house interior decoration, culminating in waterproof and fireproof tests and safety inspections. When leaving the factory, modules are complete rooms with decoration, utilities, and accessories, achieving an efficient model where 'over 90% of the processes are completed in the factory'. For types like laminated steel mesh villas, the method involves assembling wall skeletons on-site, where prefabricated steel mesh frames are used to build the wall skeletons, followed by one-time concrete pouring to integrate walls, beams, columns, and floors, enhancing overall structural integrity.

2. Vehicle Transportation and Port Transfer
Finished modules are transported to domestic ports via specialized flatbed trucks, with dimensions strictly matching international standard shipping containers to reduce transportation costs and improve space utilization. Factories adopt parallel operation modes, combining automated vertical warehouses and intelligent production lines to further shorten construction cycles. For example, module production and logistics scheduling can be carried out simultaneously, avoiding waiting times between process links in traditional construction.

3. Ocean Shipping and Global Distribution
Packaged modules are shipped to over 150 countries and regions worldwide on ocean-going freighters, with logistics timelines varying by destination: approximately 1 week to Southeast Asia, about 20 days to the Middle East, and around 1 month to Europe and the Americas. The entire logistics process is traceable, with digital systems monitoring key parameters such as module location, temperature, and humidity to ensure transportation safety.

4. On-Site Assembly and Rapid Formation
Upon arrival at overseas ports, modules are transported to construction sites and assembled using cranes and interface connections. The assembly process is similar to 'building with LEGO blocks', requiring only alignment, locking, and connecting water and electricity. For example, 63 sets of Chinese prefabricated elderly care apartments purchased by the UK were assembled in just 14 days, improving construction efficiency by over 60% compared to traditional methods. For laminated steel mesh villas, assembly involves laying floor joists after completing the chassis frame, installing prefabricated wall modules, and gradually constructing the three-dimensional structure of the house to form a stable living space.
