Production Process of Container Houses
The production process of container houses mainly includes core stages such as design, factory prefabrication, pre-installation, trial assembly, and on-site installation.
The design stage is the foundation for producing container houses. Manufacturers complete structural design and detailed drawings based on user requirements, specifying details such as the house's dimensions, layout, and functional zoning. During this stage, the modular characteristics of containers must be fully considered to ensure the feasibility of subsequent production and installation.
The factory prefabrication stage involves the processing of steel structural frames and the composite assembly of walls and roof panels. Steel is cut and welded to form frames, with the thickness of the steel for main beams and columns and the fullness of the welding process directly affecting the house's load-bearing capacity and safety. After frame completion, surface galvanization or anti-corrosion coating is applied to extend the service life. Walls and roof panels are prefabricated, filled with insulation materials (such as polyurethane), and covered to form enclosure structures with thermal insulation, fire resistance, and other properties. Some products (such as light steel frame houses) also incorporate other insulation materials into the walls to enhance energy efficiency.
The pre-installation stage integrates systems such as doors, windows, electrical, and plumbing into modules. Water and electrical lines are pre-embedded in the factory, reducing on-site wet work and improving construction efficiency. During this stage, standardization of system interfaces must be ensured for quick subsequent connections.
The trial assembly stage is conducted before shipment, simulating on-site installation to verify component compatibility, promptly identifying and correcting design or production issues, and ensuring seamless assembly of modules upon arrival.
The on-site installation stage primarily involves lifting and assembling. After modules are transported to the site, they are lifted to designated positions using lifting equipment and connected horizontally and vertically using bolts or welding. For multi-story buildings, special attention must be paid to frame connection techniques and waterproofing nodes to prevent leakage and ensure overall stability. After installation, system commissioning and acceptance are carried out to ensure normal house functionality.
The entire production process relies on modular design concepts, breaking down the building into independent units and combining factory production with on-site assembly to achieve efficient and precise construction while reducing the impact of external factors such as weather and site conditions on construction.
