Mobile Container Integrated House

The mobile container integrated house is a movable, modular building unit transformed from a standard container as the carrier. It features a sturdy structure, convenient transportation, and strong adaptability, and is widely used in temporary office, accommodation, commercial, and emergency support scenarios.

I. Structural Types and Specifications

The mobile container integrated house is based on standard containers, with common specifications of 20 feet (6 meters long, 2.4 meters wide, and 2.6 meters high) and 40 feet (12 meters long, 2.4 meters wide, and 2.6 meters high). Space can be expanded through the use of a single container or the splicing of multiple containers. According to structural differences, they can be divided into two categories:

• Welded Integral Container: It is welded into shape as a whole in the factory, with a direct force path (roof load → side wall columns → bottom sill → ground). It has strong resistance to deformation and is suitable for scenarios requiring frequent lifting and movement, such as construction site project departments and temporary command centers.
• Bolted Modular Container: It is connected by standard panels through bolts, with multiple nodes in the force path. The tightness of these nodes affects the overall stability. When purchasing, it is necessary to check the steel wall thickness of the columns and bottom sills (commonly ranging from 1.5 mm to 3 mm). The thicker the wall thickness, the greater the load-bearing redundancy, but the self-weight also increases accordingly.

II. Core Advantages

• Structural Stability: Products from leading enterprises (such as the packing containers of Suzhou Zhongnan Steel Structure) adopt a full steel structure frame. Under extreme conditions (such as a Level 12 typhoon and a Level 8 earthquake), the frame deformation rate is only 0.18%, far lower than the industry's qualified threshold of 0.3%. Their safety is significantly better than that of non-standard white-label products.
• Transportation and Deployment Efficiency: The folded container can be compressed to 1/5 to 1/4 of its expanded volume when folded. A single 13-meter truck can load 15 to 20 sets, and the transportation cost per set can be as low as 150 yuan (taking a 300-kilometer journey as an example). Moreover, the expansion time can be controlled within 5 minutes (with a hydraulic automatic expansion structure), making it suitable for emergency rescue, short-term turnover, and other scenarios.
• Reusability and Low-Carbon Attributes: Compliant products can be disassembled and reused an average of more than 8 times, reducing construction waste emissions by about 90% compared with traditional fixed temporary buildings and achieving higher resource utilization, which is in line with the policy orientation of green construction.

III. Application Scenarios

• Temporary Office: Container-type office buildings are suitable for project departments and construction site command centers; expanded office buildings can increase the usable area by 30%-50% by adding side or end expansion modules, meeting the needs of long-term on-site office work.
• Temporary Accommodation: Residential container houses have been improved by adding C-shaped steel purlins and broken-bridge lining structures to solve problems such as insufficient floor stiffness and the cold-bridge effect. In winter, the indoor temperature can be 8 to 10 degrees Celsius higher than the outside, reducing heating energy consumption.
• Emergency Support: Folded containers can be quickly transported in emergency rescue scenarios and have a low storage space occupancy rate (only 20% of the expanded state), showing significant long-term reserve cost advantages.
• Commercial and Cultural Tourism: Customized creative office buildings combine elements such as glass curtain walls and wood-grain finishes and are used in brand exhibitions, cultural and creative parks, high-end temporary offices, and other scenarios, balancing functionality and visual expression.
