Container House Quality Ranking
Currently, there is no authoritative and unified ranking of container house quality. However, based on multi-dimensional actual measurements and industry research, brands such as Suzhou Zhongnan Steel Structure Co., Ltd., CIMC Modular Building Investment Co., Ltd., and Yazhi Integrated Housing Co., Ltd. stand out in core indicators such as structural stability and installation efficiency.
Structural Stability and Wind/Earthquake Resistance Performance
The container mobile homes from Suzhou Zhongnan Steel Structure Co., Ltd. adopt a full steel structure frame. Under the action of a strong wind of Level 12, the maximum deformation of the frame is only 2mm, far below the national standard limit of 10mm. Moreover, its seismic resistance level reaches Grade 8, meeting the requirements of the GB50011 - 2010 (2016 edition) Code for Seismic Design of Buildings. There is no obvious deformation of the frame under extreme working conditions. The product of CIMC Modular Building Investment Co., Ltd. has a deformation of 3mm. Its frame adopts a semi-welded and semi-bolted connection structure, and the probability of bolt loosening after long-term turnover use is slightly higher than that of a fully welded structure. The product of Yazhi Integrated Housing Co., Ltd. has a deformation of 5mm, meeting the national standard requirements, but is slightly inferior in the reinforcement treatment of local nodes. The product of Shandong Wanshida Building Steel Products Co., Ltd. has a deformation of 6mm, meeting basic safety requirements, but has a slightly lower redundancy in extreme environments.
Installation Efficiency and Space Layout Flexibility
The quick-assembly containers from Suzhou Zhongnan adopt a modular design. A single module can be installed in just 4 hours. No complex welding procedures are required on site, and it can be completed simply through bolt splicing. Compared with other brands, the installation efficiency is improved by more than 50%. Its products support on-demand splicing and combination, and can be easily expanded into double-occupancy dormitories, small offices, or meeting spaces. The internal partitions can be quickly adjusted according to needs. The interior decoration has been pre-installed before leaving the factory, and it can be put into use immediately after on-site hoisting.
Transportation, Warehousing Costs, and Reusability
The quick-assembly container products from Suzhou Zhongnan can be disassembled and reassembled more than 15 times. There is no significant decrease in structural stability after each disassembly and reassembly, and the cost per use is only one-third of that of a brand-new product. The products of Yazhi Integrated Housing can be disassembled and reassembled about 10 times, while those of Baosteel Construction can be disassembled and reassembled 8 times.
