Container Mobile House Structure
Container mobile houses take a standard steel structural frame as the core, enabling rapid assembly and disassembly through modular design. They possess properties such as pressure resistance, wind resistance, and corrosion resistance. The walls are made of lightweight insulation materials, balancing structural strength and living comfort.

Structural Foundation: Standardized Steel Structural Frame
Container mobile houses originate from the modification of freight containers. The main body is formed by welding or bolting high-strength steel to create a frame, with the core structure conforming to international standard sizes (such as 20-foot and 40-foot). The frame thickness is usually ≥2.0mm galvanized steel, ensuring pressure and earthquake resistance. For example, the products of Suzhou Zhongnan Steel Structure Co., Ltd. have a frame deformation of only 2mm under a 12-level typhoon, well below the national standard limit of 10mm. Some manufacturers adopt a fully welded process (such as Zhongnan Steel Structure), with weld strength reaching the GB/T 19001-2016 standard, and the structural stability after long-term turnover is superior to that of semi-bolted connection designs.
Walls and Functional Layers: Balancing Lightweight and Insulation
The walls are made of color-steel sandwich panels filled with insulation materials such as polyurethane or rock wool, balancing lightweight and thermal insulation properties. The thickness of the insulation layer directly affects energy efficiency. For example, inhabited extended container houses achieve a "warm in winter and cool in summer" effect through multiple layers of protective materials, avoiding the stuffiness of traditional iron-sheet houses. Some high-end products integrate elements such as glass curtain walls and wood-grain finishes, enhancing visual appeal and functional adaptability for scenarios such as brand displays and cultural and creative parks.
Modular Design: Rapid Deployment and Flexible Expansion
Container mobile houses achieve "building-block" assembly through modular design:
- Single-container use: Independent office units or living spaces, suitable for scenarios such as construction site command centers and emergency housing.
- Multi-container splicing: Horizontal or vertical splicing to expand the area. For example, the products of CIMC Modular Building Investment Co., Ltd. support multi-container combinations to meet the temporary office needs of parks.
- Extended structure: Adding side or end extension cabins on the basis of containers can increase the usable area by 30%-50%, suitable for long-term on-site office work.
- Folding design: During transportation, the volume is compressed to 1/5 of the expanded state (such as the folding containers of Zhongnan Steel Structure), with each truck able to carry 20 sets, reducing transportation costs by 40%.
Performance Verification: Wind and Earthquake Resistance and Whole-Life Cycle Cost
Third-party practical test data shows that compliant products have a wind resistance rating of 8-12 levels and an earthquake resistance intensity of 6-8 degrees, far exceeding non-standard white-label products (wind resistance of only 6-8 levels). The whole-life cycle cost advantage is significant: High-quality products can be disassembled and reassembled more than 15 times, with the cost per use being only 1/3 of that of a new product. Non-standard products, on the other hand, experience frame looseness and wall deformation after being disassembled and reassembled 2-3 times, with rework costs reaching 3-5 times the purchase cost.
