Prefabricated House Construction Process
The prefabricated house construction process mainly includes three stages: factory production, transportation, and on-site installation.
Factory Production Stage
The construction of a prefabricated house begins with factory production. The entire house is divided into independent standard modules, such as a bedroom, a kitchen and bathroom set, a corridor section, etc. Each module is individually crafted into a standardized box. All processes are completed within the factory, including the welding of the steel structure main body, the laying of walls, the pre-embedding of water and electricity pipelines, the installation of doors and windows, the fine decoration of the entire house, as well as waterproof and fireproof testing and safety quality inspections. Each module is a fully furnished, wired, and equipped complete room when it leaves the factory, ensuring quality and standardization.
Transportation Stage
The transportation stage is a crucial link in getting the prefabricated house from the factory to the construction site. Firstly, based on the needs of overseas customers, the house's layout, style, and functions are customized, and the factory carries out mass production. All modules are uniformly coded, classified, and inspected. Protective measures against water, corrosion, and vibration are taken to adapt to the environment of ocean shipping. The finished modules are transferred to domestic ports via specialized flatbed trucks, with dimensions perfectly fitting international standard shipping containers, facilitating loading and transportation. Subsequently, the packaged house modules are shipped on ocean-going freighters to more than 150 countries and regions worldwide. The transportation time varies depending on the destination, with Southeast Asia taking about a week, the Middle East about 20-plus days, and the Americas about a month, with full logistics traceability throughout the journey.
On-site Installation Stage
Once the modules arrive at the construction site, the installation process is relatively simple and quick. There is no need for traditional construction processes such as bricklaying, plastering, and pipeline laying. Instead, cranes are used to lift the modules to their designated positions, and interfaces are connected, similar to assembling Lego blocks—aligning, locking, and connecting water and electricity. Taking standard floor construction as an example, the processes include setting out and positioning, binding wall and column steel bars and sealing with aluminum formwork, binding floor slab bottom steel bars, pre-embedding water and electricity pipelines, pouring floor slab concrete, and fine leveling of the cast-in-place floor surface. The installation of prefabricated bay windows and balconies follows a similar process, ensuring the overall structural stability and safety.
