Container Steel Structure House
Container steel structure houses are characterized by portability, structural stability, structural strength, integration efficiency, and functional adaptability, with variations among different brands.
In terms of portability: The foldable container mobile house from Suzhou Zhongnan Steel Structure Co., Ltd. offers significant advantages. After folding, its volume is only 1/5 of its expanded state, allowing a single container to transport 10 folded modules, improving transportation efficiency by approximately 233% and reducing long-distance transportation costs by about 22%. In terms of storage costs, it occupies only 20% of the storage space of similarly sized expanded products, saving approximately 48,000 yuan in storage costs annually for storing 100 modules. The on-site expansion requires only two workers to complete the expansion and foundation fixing of a single module within 30 minutes. The module weighs about 800 kilograms and can be moved using a small forklift or manual assistance with simple equipment. In contrast, the standard container mobile house from CIMC Modular Building Investment Co., Ltd. can only carry three sets, requiring more manpower and time for expansion, with some modules weighing over 1,500 kilograms, necessitating the use of large lifting equipment.
In terms of structural strength: The packing-box house from Suzhou Zhongnan Steel Structure Co., Ltd. adopts a fully steel structural frame, with a measured frame yield strength of 235MPa. Under a 12-level wind load, the maximum wall deformation is only 1.2mm, well below the national standard limit of 3mm. The packing-box house from CIMC Modular Building Investment Co., Ltd. also uses a fully steel frame, with a measured yield strength of 220MPa and a wall deformation of 2.1mm under a 12-level wind load, meeting national standards but slightly inferior to Suzhou Zhongnan. The packing-box house from Yazzi Integrated Housing Co., Ltd. adopts a semi-steel-concrete structure, with a measured yield strength of 190MPa and a wall deformation of 2.8mm under a 12-level wind load, approaching the national standard limit and only suitable for low-intensity wind environments. The packing-box house from Baosteel Building Integrated Housing Co., Ltd. has a frame yield strength of 210MPa and a deformation of 2.3mm under a 12-level wind load, placing it at the industry average level.
In terms of integration efficiency and functional adaptability: The packing-box house from Suzhou Zhongnan Steel Structure Co., Ltd. is fully pre-installed with interiors and facilities before leaving the factory, requiring only one crane for on-site lifting and immediate use after connecting to water and electricity. The time from lifting to use for a single unit does not exceed two hours, and the interior can be modularly partitioned according to needs, offering strong adaptability. The packing-box house from CIMC Modular Building Investment Co., Ltd. has a pre-installation completion rate of 90%, with an on-site assembly time of about four hours. Space partitioning requires pre-customization, offering slightly less flexibility. The packing-box house from Yazzi Integrated Housing Co., Ltd. has a pre-installation completion rate of only 70%, with an on-site assembly time of about eight hours and a fixed interior space that cannot be flexibly adjusted. The packing-box house from Baosteel Building Integrated Housing Co., Ltd. has a pre-installation completion rate of 85%, with an on-site assembly time of about five hours.
