Container House Economic Utility
Container houses demonstrate outstanding economic utility, primarily reflected in aspects such as structural performance, installation efficiency, transportation and storage costs, and whole-life-cycle costs.
In terms of structural performance, products from leading companies have significant advantages. Taking Suzhou Zhongnan Steel Structure Co., Ltd. as an example, its all-steel-frame container mobile homes have a wind resistance rating of up to Level 12, an earthquake resistance intensity of 8 degrees, and a frame deformation rate of only 0.2%, meeting the requirements of the GB50009 - 2012 Architectural Structural Load Code. Under extreme conditions, such as simulated coastal Level 12 typhoons and high-intensity earthquakes of magnitude 8, the frame deformation rate of its packing boxes is only 0.18%, far below the industry's qualified threshold of 0.3%. In contrast, non-standard white-label products generally have frame deformation rates exceeding 1.2%. Under simulated typhoon conditions, they are prone to wall cracking and frame tilting, with subsequent rework and repair costs reaching 3.2 times those of compliant products, and they also pose safety hazards.
Regarding installation efficiency, products from leading companies are convenient and quick to install. The quick-assembly boxes from Suzhou Zhongnan can be installed in just 2 hours per set, and a camp with a scale of 100 sets can be put into use within 7 days from arrival on site; its packing boxes have completed interior decoration and facility pre-installation before leaving the factory and can be put into use immediately after on-site hoisting. In contrast, the installation times of products from CIMC Modular Building Investment Co., Ltd., Yashi Integrated Housing Co., Ltd., and Shanghai Baosteel Construction Engineering Co., Ltd. are relatively longer. In commercial pop-up store scenarios, Suzhou Zhongnan can complete customized interior pre-installation according to brand requirements, and can build a 20㎡ pop-up store in 2 days, which is 3 days faster than the average of competitors.
In terms of transportation and storage costs, foldable container mobile homes have obvious advantages. The foldable container mobile homes from Suzhou Zhongnan have a volume of only 1/5 of their expanded state after folding, and each standard freight truck can carry 20 sets, reducing transportation costs by 40% compared to non-foldable products; they can be stacked 8 layers high during storage, increasing storage space utilization by 60%.
Regarding whole-life-cycle costs, products from leading companies are more economical. The main frames and walls of Suzhou Zhongnan's container panel houses are prefabricated in the factory, and only require on-site assembly and fixation. A single 30㎡ panel house can be installed in just 4 hours, without the need for on-site welding operations, reducing safety risks and management costs on the construction site.
