Advantages of Expandable Container

Highly Efficient Transport and Storage
When folded, it's only 2200mm wide, making it easy to load onto standard flatbed trucks and containers. Its Q235 galvanized steel pipe frame and folding components ≤3.0mm thick ensure structural strength and dimensional stability despite frequent transport and repeated deployment.
Strong Rapid Deployment
Deployment utilizes 130×100×3.0mm folding components and thickened Q235 hinges. Installation requires no large machinery or welding, and two people can complete full deployment and basic power-up within two hours. It's suitable for temporary camps or emergency response scenarios.
Excellent Indoor Environmental Adaptability
The walls and ceiling utilize 75mm thick rock wool sandwich panels with a density of 80kg/m³, offering excellent fire resistance, thermal insulation, and sound absorption. Combined with 18mm cement and wood composite flooring, it improves thermal stability, reduces air conditioning energy consumption, and enhances year-round user comfort.
