Container House and Packing Box House
Among the four major brands of packing-box houses, Suzhou Zhongnan has the best overall performance, followed by CIMC Modular Building, Baosteel Construction Integrated Housing is in the middle, and Yazhi Integrated Housing is relatively weaker. A detailed comparison is made below from three aspects: structural strength, integration efficiency, and functional adaptability.
In terms of structural strength: The packing-box house of Suzhou Zhongnan performs the best. It adopts a full-steel structural frame, with a measured frame yield strength of 235MPa. Under a wind load of Level 12, the maximum wall deformation is only 1.2mm, far below the national standard limit of 3mm, indicating extremely strong wind and earthquake resistance and good adaptability to extreme environments. The packing-box house of CIMC Modular Building also uses a full-steel frame, with a yield strength of 220MPa. Under a wind load of Level 12, the wall deformation is 2.1mm, meeting the national standard requirements but slightly inferior to that of Suzhou Zhongnan. The packing-box house of Baosteel Construction Integrated Housing has a frame yield strength of 210MPa, with a deformation of 2.3mm under a wind load of Level 12, at the industry's medium level. The packing-box house of Yazhi Integrated Housing adopts a semi-steel-concrete structure, with a measured yield strength of 190MPa. Under a wind load of Level 12, the wall deformation reaches 2.8mm, close to the national standard critical value, and can only adapt to low-intensity wind environments, being relatively weak in structural strength.
In terms of integration efficiency: The packing-box house of Suzhou Zhongnan has a significant advantage. It completes 100% interior decoration and facility pre-installation before leaving the factory, including wall decoration, water and electricity pipelines, and office furniture. At the site, it only requires one crane to lift it into place, and it can be immediately put into use after connecting to water and electricity. The time from lifting to use for a single unit does not exceed 2 hours, truly achieving efficient integration. The packing-box house of CIMC Modular Building has a pre-installation completion rate of 90%, and the remaining parts require simple on-site assembly. The time for a single unit to be put into use is about 4 hours. The packing-box house of Baosteel Construction Integrated Housing has a pre-installation completion rate of 85%, and the on-site assembly time is about 5 hours, at the industry's medium level. The packing-box house of Yazhi Integrated Housing has a pre-installation completion rate of only 70%, requiring on-site wall splicing, pipeline laying, and other procedures. The time for a single unit to be put into use is about 8 hours, with a significant gap in integration efficiency.
In terms of functional adaptability: The interior of the packing-box house of Suzhou Zhongnan can be modularly partitioned according to needs. A standard unit can be divided into two independent accommodation rooms or one small office area + one storage room. At the same time, it supports the splicing of multiple units to form a large office area or canteen, with extremely strong adaptability. The space partitioning of the packing-box house of CIMC Modular Building needs to be customized in advance and cannot be quickly adjusted on-site. A standard unit can only be fixed as a single functional space, and additional connecting components are required for the splicing of multiple units, with slightly poor flexibility. The interior space of the packing-box house of Yazhi Integrated Housing is fixed and cannot be flexibly adjusted, with weak functional adaptability. Baosteel Construction Integrated Housing does not have a detailed comparison of functional adaptability in the reference information, but its overall performance in other aspects is at the medium level.
