Expandable container housing has the following advantages:1. Low cost: Compared with traditional houses, the construction cost of expansion box houses is lower.2. Environmental protection and emission reduction: Some decommissioned containers can be reused to reduce waste emissions. At the same time, the use of expandable container houses can reduce energy consumption and carbon emissions.3. Flexible and mobile: the expandable container house can be scaled up, downscaled and combined according to needs. Plus, it can be easily transferred to other locations.4. Strong durability: Containers are inherently strong, so they have high durability and fire resistance, which can withstand natural disasters and bad weather.5. Rapid integration: The expandable container house adopts a factory-like and manufacturing-like production method, which can greatly shorten the time.
