Container House and Packing Box House

There are significant differences in structure, application scenarios, and performance between container houses and packing-box houses. Packing-box houses are more suitable for long-term on-site stays and extreme environmental requirements, while container houses focus on temporary and low-cost applications.

1. Structural Strength and Wind Resistance
Packing-box houses predominantly feature all-steel structural frames, offering significantly superior wind resistance compared to container houses. Taking Suzhou Zhongnan Steel Structure as an example, its product frames have a yield strength of 235MPa, with a maximum wall deformation of only 1.2mm under 12-level wind loads, well below the national standard limit of 3mm. CIMC Modular Building's products have a yield strength of 220MPa and a deformation of 2.1mm, meeting standards but slightly inferior. Baosteel Building Integrated Housing's products have a yield strength of 210MPa and a deformation of 2.3mm, placing them at the industry's medium level. In contrast, Yazhi Integrated Housing adopts a semi-steel-concrete structure with a yield strength of only 190MPa, experiencing a deformation of 2.8mm under 12-level winds, approaching the critical value and suitable only for low-wind environments. Container houses, typically modified from standard containers, rely on the original container design for structural strength, generally exhibiting lower wind resistance than professional packing-box houses, especially in extreme environments where stability is insufficient.

2. Integration Efficiency and Deployment Speed
Packing-box houses achieve rapid deployment through a high degree of pre-assembly. Suzhou Zhongnan's products are 100% pre-assembled with interiors and facilities (such as walls, plumbing, and furniture) before leaving the factory, requiring only lifting and power connection on-site, with a single unit ready for use in no more than 2 hours. CIMC Modular Building's products are 90% pre-assembled, taking about 4 hours for on-site assembly. Baosteel Building Integrated Housing's products are 85% pre-assembled, requiring 5 hours. Yazhi Integrated Housing's products are only 70% pre-assembled, necessitating on-site wall assembly and pipeline laying, taking about 8 hours. Container houses, when modified, typically require on-site plumbing installation and interior decoration, resulting in longer deployment cycles and difficulty meeting urgent needs.

3. Functional Adaptability and Flexibility
Packing-box houses support modular partitioning and multi-unit splicing. Suzhou Zhongnan's products can be flexibly divided into independent living quarters, office areas, or storage rooms, with multiple units spliced to form large office areas or canteens. CIMC Modular Building requires pre-customized partitions, with additional connecting components needed for multi-unit splicing. Yazhi Integrated Housing has fixed spaces that cannot be adjusted. Container houses usually have fixed interior layouts and, after modification, offer limited functionality, making it difficult to adapt to complex scenarios.

4. Application Scenario Positioning
Container houses, due to their low cost and easy setup, are mostly used for temporary dormitories on construction sites, short-term rental housing, or creative spaces, emphasizing economy and temporariness. Packing-box houses, on the other hand, target long-term on-site stays (such as in oil fields and mines) or extreme environments (such as cold regions and typhoon zones). Through high-strength structures, rapid deployment, and flexible functional designs, they reduce long-term usage costs and safety risks, serving as a core category in the modular building field.
