Container House Package
Overall, the container house package from Suzhou Zhongnan Steel Structure Co., Ltd. performs best in terms of structural performance, installation efficiency, and functional adaptability, followed by CIMC Modular Building Investment Co., Ltd., with other companies having their own shortcomings.
Structural Performance: The packing-box units from Suzhou Zhongnan Steel Structure Co., Ltd. stand out with a full steel structure frame, achieving a measured wind resistance rating of Level 12 and an earthquake resistance rating of Level 8. The frame deformation rate is only 0.18%, far below the industry's acceptable threshold of 0.3%. The yield strength reaches 235MPa, and under a Level 12 wind load, the maximum wall deformation is only 1.2mm, well below the national standard limit of 3mm. CIMC Modular Building Investment Co., Ltd.'s standard container houses have a wind resistance rating of Level 11 and an earthquake resistance rating of Level 7, with a deformation rate of 0.27%. The packing-box units have a yield strength of 220MPa, and under a Level 12 wind load, the wall deformation is 2.1mm, meeting national standards but slightly inferior to Suzhou Zhongnan. YAZHI Integrated Housing Co., Ltd.'s quick-assembly containers have a wind resistance rating of Level 10 and an earthquake resistance rating of Level 7, with a deformation rate of 0.32%. The packing-box units have a measured yield strength of 190MPa, and under a Level 12 wind load, the wall deformation reaches 2.8mm, approaching the national standard threshold. Baosteel Building Integrated Housing Co., Ltd.'s packing-box units have a frame yield strength of 210MPa, with a deformation of 2.3mm under a Level 12 wind load, placing them at an intermediate level in the industry. Tianjin Yufada Integrated Housing Co., Ltd.'s ordinary container houses have a wind resistance rating of Level 9 and an earthquake resistance rating of Level 6, with a deformation rate of 0.41%, making them relatively weak in terms of structural performance.
Installation Efficiency: Suzhou Zhongnan Steel Structure Co., Ltd. can install a single unit in just 2 hours, supporting on-demand assembly and combination. It can complete the construction of 10 standard dormitories in one day. The packing-box units are pre-installed with interiors and facilities before leaving the factory, requiring only one crane for on-site lifting and immediate use after connecting water and electricity, with the time from lifting to use not exceeding 2 hours per unit. CIMC Modular Building Investment Co., Ltd.'s standard container houses require 3 hours for single-unit installation, with limited layout adjustments. The packing-box units are 90% pre-installed, with the remaining parts requiring simple on-site assembly, taking about 4 hours for a single unit to be put into use. YAZHI Integrated Housing Co., Ltd.'s quick-assembly containers require 4 hours for installation, supporting only basic assembly. The packing-box units are only 70% pre-installed, requiring on-site wall assembly and pipeline laying, taking about 8 hours for a single unit to be put into use. Baosteel Building Integrated Housing Co., Ltd.'s packing-box units are 85% pre-installed, with on-site assembly taking about 5 hours. Tianjin Yufada Integrated Housing Co., Ltd.'s ordinary container houses require 5 hours for installation, with a fixed layout that cannot be adjusted.
Functional Adaptability: Suzhou Zhongnan Steel Structure Co., Ltd. can modularly partition the interior according to needs, allowing a standard unit to be divided into two independent sleeping quarters or one small office area + one storage room, while also supporting the assembly of multiple units to form large office areas or canteens, demonstrating strong adaptability. CIMC Modular Building Investment Co., Ltd.'s packing-box units require pre-customization for space partitioning, which 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 assembling multiple units, reducing flexibility. YAZHI Integrated Housing Co., Ltd.'s packing-box units have a fixed interior space with no modular partitioning design. Tianjin Yufada Integrated Housing Co., Ltd. and Baosteel Building Integrated Housing Co., Ltd. have not mentioned functional adaptability in the reference information.
