How Container Houses Are Produced

The production of container houses mainly adopts a modular design concept, dividing the building into multiple independent modules. The manufacturing and pre-assembly of the main structure, enclosure system, water and electricity pipelines, and interior decoration are completed in the factory, and then transported to the site for rapid assembly.

I. Design Disassembly and Standardization

The production of container houses begins with systematic design, dividing the building into standardized components such as the bottom surface, top surface, and four side surfaces, or into independent modules according to function (e.g., bathroom and kitchen modules). During the design phase, module dimensions, load-bearing structures, and connection methods need to be determined to ensure compliance with international standards (e.g., a 20-foot container can bear 25 tons, and a 40-foot container can bear 45 tons) and building codes. Modular design supports flexible combinations and can adapt to different scenarios such as residences, shops, and art galleries.

II. Factory Production Process

1. Structural Fabrication: The module frames are welded using hot-dip galvanized cold-formed steel or square steel to ensure structural strength. For example, the chassis crossbeams use 4×8×2.0 square steel with a spacing of 35 centimeters, and the columns and roof ring beams are fully welded with 5×5×2.0 square steel.
2. Enclosure System Installation: The walls and roof panels are made of fire-resistant polyurethane sandwich panels or 50mm thick purification panels, providing both thermal insulation and fire resistance. Standard-sized sliding windows are installed in the windows, and the doors are specially made color steel plate doors.
3. Mechanical, Electrical, and Interior Integration: Water and electricity pipelines are pre-embedded in the factory, and sanitary equipment, cabinets, wardrobes, etc., are installed. Positions for air conditioning holes and switch sockets are also reserved. Some production lines also integrate processes such as floor leather laying and lighting installation.
4. Quality Inspection and Identification: Each module must pass precision inspection (with manufacturing errors controlled within 1-2 millimeters) and be given a unique QR code identity label. Scanning the label allows tracing of all production records.

III. On-site Assembly and Commissioning

After being transported to the project site, the modules are quickly spliced together using lifting equipment to form a complete building. The assembly process is similar to 'building with blocks', with multiple processes carried out in parallel, shortening the construction period by more than 60% compared to traditional methods. On-site, only module connection, waterproof glue sealing (using glass curtain wall waterproof glue), and a small amount of adjustment work are required before the building can be put into use.

IV. Technical Advantages and Application Scenarios

The production of container houses achieves industrial upgrading of construction through factory manufacturing, standardized design, and modular assembly. Its advantages include: short construction period, controllable precision, reusable disassembly, and turnover use. Common product types include packing-box units (for construction site dormitories and office areas), light steel frame houses (for self-built houses and homestays), and functional kiosks (such as security kiosks and environmental protection public toilets).
