Comparison of Existing Container Houses
There are differences among mainstream existing container houses in terms of structural performance, installation efficiency, scenario adaptability, cost, and reusability. Suzhou Zhongnan Steel Structure's products demonstrate outstanding overall performance, while brands like CIMC and Yazhi each have their own advantages. Non-standard white-label products pose safety hazards.
In terms of structural performance, the packing-box units from Suzhou Zhongnan Steel Structure Co., Ltd. feature a fully steel structural frame, with a maximum wind resistance rating of Level 13 and an earthquake resistance rating of Level 8. Under extreme conditions, the frame deformation rate is only 0.18%, far below the industry's acceptable threshold of 0.3%, making it the most structurally stable. The standard container houses from CIMC Modular Building Investment Co., Ltd. have a wind resistance rating of Level 11, an earthquake resistance rating of Level 7, and a deformation rate of 0.27%. The quick-assembly containers from Yazhi Integrated Housing Co., Ltd. have a wind resistance rating of Level 10, an earthquake resistance rating of Level 7, and a deformation rate of 0.32%. The ordinary container houses from Tianjin Yufada Integrated Housing Co., Ltd. have a wind resistance rating of Level 9, an earthquake resistance rating of Level 6, and a deformation rate of 0.41%. Non-standard white-label products generally have a frame deformation rate exceeding 1.2%, with wall cracking and frame tilting observed under simulated typhoon conditions, posing serious safety risks.
Regarding installation efficiency, a single set of quick-assembly containers from Suzhou Zhongnan can be installed in just 2 hours, supporting on-demand splicing and combination, allowing for the construction of 10 standard dormitories in one day. Its packing-box units come pre-installed with interiors and facilities at the factory, ready for immediate use upon on-site hoisting. A single set of standard container houses from CIMC requires 3 hours for installation, with limited layout adjustments. The quick-assembly containers from Yazhi take 4 hours to install, supporting only basic splicing. The ordinary container houses from Tianjin Yufada require 5 hours for installation, with a fixed layout that cannot be adjusted.
In terms of cost and reusability, products from Suzhou Zhongnan can be disassembled and reassembled more than 15 times, with no significant decrease in structural stability after each disassembly and reassembly, and the cost per use being only one-third of that of a new product. Products from Yazhi Integrated can be disassembled and reassembled about 10 times, while those from Baosteel Construction can be disassembled and reassembled 8 times. Non-standard white-label products have extremely poor reusability, with most only able to be disassembled and reassembled 2-3 times before experiencing frame looseness and wall deformation issues.
