The Expandable Container House offers the highest space utilization among container house types. The design concept is simple: during transport, it maintains the compact width of a standard container; on-site, hydraulic or manual sliding rails push the side panels outward, nearly doubling or tripling the usable floor area. As a premier expandable container house factory, Zhongyi Zhiji produces a diverse series including 10FT, 20FT, 30FT, 40FT, and Small Expandable Container House models. Each unit utilizes high-strength galvanized steel frames and fire-retardant insulated sandwich panels, ensuring excellent thermal insulation and weather protection. Installation is highly efficient, allowing workers to complete expansion and fixation quickly. These products are widely used in construction site offices, tourist resort cabins, remote mining dormitories, and emergency shelters.
