How to Make a Container House

Making a container house involves steps such as design, material preparation, structural processing, wall and roof panel treatment, system pre-installation, on-site assembly, and post-maintenance. Details are as follows:

I. Design Phase
Determine the functional divisions of the house (such as bedrooms, living rooms, bathrooms, etc.) based on usage needs. Select container specifications (e.g., 20-foot or 40-foot containers) and combination methods (splicing, staggered stacking). For example, 2-3 containers can be combined to form a flat layout of approximately 100 square meters or increase spatial hierarchy through staggered design. The design should consider load-bearing, ventilation, and lighting requirements and draw detailed structural drawings.

II. Material and Structural Processing

1. Frame Welding: Use hot-dip galvanized cold-formed steel or channel steel (e.g., 5×10 channel steel) to weld the chassis and columns, forming a steel structural framework. The column thickness should be ≥1mm to ensure support strength.
2. Surface Treatment: After grinding the welded cuts, apply epoxy primer and topcoat to prevent rust. The chassis can be laid with building templates or cement fiber boards to enhance load-bearing capacity.

III. Wall and Roof Panel Treatment

1. Composite Processing: Wall and roof panels are made of rock wool, glass wool, or polyurethane sandwich panels, filled with insulation material and covered (e.g., with metal panels or calcium silicate boards) for both thermal insulation and fire resistance.
2. Door and Window Reservation: Cut openings according to the design, install fire-resistant doors and windows and security nets, and seal the joints with glass curtain wall waterproof sealant to prevent leakage.

IV. System Pre-installation
Pre-embed electrical, water supply and drainage, and ventilation systems in the factory. For example, lay electrical circuits, install lighting switches and sockets, and reserve air conditioning holes; set up skylights or eaves on the roof to improve lighting and shading effects.

V. On-site Assembly and Debugging

1. Foundation Construction: After handling approval procedures based on land properties (such as homestead or leased land), pour concrete piers or pile foundations to elevate the containers for moisture prevention.
2. Module Splicing: Use a crane to lift the prefabricated modules into place and fix the splicing joints with bolts or welding to ensure structural stability.
3. Function Debugging: Connect water and electricity pipelines, test ventilation, lighting, and thermal insulation performance, and adjust details (such as folding furniture and awnings).

VI. Post-maintenance

1. Rust Prevention: Regularly inspect welds, corners, and other parts. Immediately grind and repaint any rust spots found; repaint the anti-corrosion layer every 8-12 years in inland areas and shorten the interval to 3-5 years in coastal areas.
2. Waterproof Sealing: Replace the sealant around doors, windows, and splicing joints every 5-7 years, and clean roof leaves to prevent water accumulation and corrosion.
3. Condensation Prevention: Lay vapor barriers on walls and roofs, install exhaust fans or high windows, and keep the interior dry.
