Renovation of Container Modular Houses

The renovation of container modular houses requires adherence to professional processes and attention to detail. Both personal renovations and professional production must ensure safety and functionality.

1. Renovation Process by Professional Manufacturers

1. Design Confirmation
   Professional manufacturers typically refine the dimensions and connection methods of steel structural frameworks based on architectural plans provided by clients or standard atlases developed in-house. For example, load-bearing structural parameters are determined according to the intended use of the house to ensure the stability of modular assembly.

2. Material Preparation
   High-strength weathering steel is selected as the primary material, supplemented by rock wool or polyurethane insulation layers, fire-resistant panels, and waterproof membranes. Materials must comply with building safety standards, such as achieving a Class A fire rating and an insulation layer thermal conductivity below 0.024W/(m·K).

3. Workshop Processing and Assembly
   Workers cut, weld, and assemble steel plates to form the container framework, then install walls, floors, ceilings, and water and electrical pipelines. Interior decoration includes wall finishes, securing bathroom fixtures, and installing furniture. For example, drainage pipes in bathroom areas must be pre-embedded and waterproofed, and furniture must be fixed to the steel structure to prevent shifting during transportation.

4. Quality Inspection and Adjustment
   Multiple quality inspection points are set up throughout the process, such as welding strength tests (requiring at least 80% of the base material's strength), water spray tests (lasting 2 hours without leakage), and electrical circuit insulation tests (resistance values must exceed 0.5MΩ). Adjustments are made based on different terrains and climates, such as increasing wall thickness to 150mm in cold regions, upgrading insulation materials to reflective types in tropical areas, and optimizing window and door layouts (e.g., reducing opening sash areas in windy regions).

2. Practical Cases of Personal Renovations

1. Renovation of a Luxury Flat
   A couple transformed two containers into a three-bedroom, one-living-room home over four years, with steps including:

• Building a corridor roof framework using light steel keels to enhance structural integrity;
• Constructing wall frameworks and installing the corridor body, using waterproof panels instead of traditional waterproof cloth to save time;
• Focusing on interior decoration details, such as adopting a composite structure of wood veneer and soundproof cotton for walls to improve living comfort.

2. Renovation of Rural Scrap Containers
   Another couple converted two scrap containers into a rural residence, with key steps including:

• Expanding interior space by spacing containers 1.5 meters apart and building connecting structures with wooden boards;
• Roof treatment: sealing with oriented strand board (OSB), laying waterproof tarps, securing wooden frame strips, and installing aluminum corrugated tiles;
• Window and door optimization: reserving sufficient window space, using double-glazed units to enhance thermal insulation, and sealing gaps between window frames and walls with sealant.

Both professional production and personal renovations must strictly adhere to building safety regulations, focusing on structural stability, waterproof and fireproof performance, and material durability to ensure long-term safety of the house.
