Space design: The design adopts a double-wing folding structure, resulting in a compact size after folding, making it easy to transport. Upon unfolding, the usable space can be significantly increased. For instance, the basic model of 20-foot specification can create a space of approximately 36 square meters after unfolding, which can be cleverly arranged into a layout of two bedrooms, one living room, and one bathroom, meeting various needs such as family living and temporary office work.
    Energy system: Integrated solar power supply module on top, equipped with double-glass double-sided photovoltaic panels, capable of efficiently converting solar energy into electricity. Coupled with an energy storage system, it can store excess electricity and achieve sustainable operation in off-grid environments. Supports two power modes: 220V and 380V. 220V is suitable for household use and electric vehicle charging, while 380V is suitable for industrial and commercial use. It also allows real-time monitoring of the energy storage device status via a mobile phone or computer.
    Structure and Material: The overall design features a light steel hot-dip galvanized groove frame, enhancing waterproof, anti-pry, sealing, and insulation performance. Some product casings are made of aviation-grade aluminum plates with fluorocarbon baking paint, combining aesthetics and durability. The interior uses refrigerator-grade polyurethane insulation material, providing excellent insulation performance.
    Convenience: The box is pre-installed with a comprehensive wiring system, lighting switches, and a full set of sanitary facilities. Users do not need to carry out complex secondary decoration. They only need to complete simple connection procedures to quickly put it into use, greatly reducing the time period from transportation to activation.
    Application Scenarios: It can be applied to temporary command posts, scenic spot shops, wilderness camps, post-disaster resettlement, and other scenarios. For example, Hanliang Shuangyi's expandable container houses were once used in the post-disaster resettlement project in Africa by the United Nations High Commissioner for Refugees, and Ruijie Green Construction's products served as modular housing for the athletes' village at the Paris Olympics
