How to Make Container Houses

The production of container houses involves stages such as design, manufacturing, and assembly, with core steps including steel frame welding, wall and roof panel prefabrication, utility line embedding, and on-site assembly.

I. Design Phase

Usage requirements (such as residential, office, or commercial purposes) must be clarified, and spatial planning should be carried out in combination with standard container sizes (a 20-foot container has a load capacity of 25 tons, and a 40-foot container has a load capacity of 45 tons). Through adaptive combination design of containers, expansion from small single-container units to large modular buildings can be achieved, such as double-story residences or three-story commercial blocks. The design should consider structural safety, including the thickness of the steel for main beams and columns, the fullness of the welding process, and whether the container has undergone galvanizing or anti-corrosion coating.

II. Manufacturing Phase

1. Steel Frame Welding: The chassis uses channel steel or square steel to weld crossbeams, and the columns and roof ring beams are fully welded with section steel to ensure load-bearing capacity. For example, the crossbeam spacing on the chassis of a 3m×6m residential container is 35 centimeters, and the columns use 5×5×2.0 square steel.
2. Wall and Roof Panel Prefabrication: Wall and roof panels commonly use 50mm thick cleanroom panels with white surfaces on both sides, sliding windows at the windows, and specially made color steel plate doors. The chassis is laid with 18mm thick construction formwork, with a load capacity of up to 200 kilograms per square meter.
3. Utility Line Embedding: Air conditioning holes are reserved on the chassis floor, lighting fixtures and switch sockets (60 centimeters from the floor) are installed, and waterproof floor leather is laid.
4. Anti-corrosion and Sealing Treatment: After welding is completed, the container body needs to be galvanized or coated with anti-corrosion paint as a whole. The waterproof adhesive for the roof panels uses glass curtain wall special adhesive, which has 5-6 times stronger waterproof performance than ordinary adhesive.

III. On-site Assembly Phase

After the components are prefabricated in the factory, they are transported to the site for rapid assembly. The modular design supports repeated disassembly and reassembly and turnover use, making it suitable for scenarios such as temporary construction sites and emergency housing. During assembly, attention should be paid to the connection technology of multi-story frames and the treatment of waterproof joints. For example, for double-story buildings, it is necessary to confirm whether the manufacturer has the relevant technical capabilities.

IV. Precautions

1. Material Selection: The steel should specify the cold galvanizing or hot galvanizing process, and the decoration materials should comply with fire safety standards (such as the bulk density of rock wool and the thickness of polyurethane spraying).
2. Communication and Coordination: Designers need to communicate details with the production supervisor to avoid misunderstandings; material arrival should be strictly arranged according to the schedule to avoid project delays.
3. Regional Adaptation: The design should be adjusted according to the terrain and climate. For example, mountain projects need to strengthen structural stability, and humid areas need to enhance anti-corrosion treatment.
