Mobile House Container Panel
Mobile house container panels, centered around high-strength weathering steel, rock wool composite structures, and anti-corrosion coatings, combine structural safety, thermal insulation, anti-corrosion, and rapid deployment features, making them widely applicable in temporary buildings and some permanent scenarios.
Material and Structural Characteristics
The main body of the container panel is made of high-strength weathering steel (such as Q355B grade), with a yield strength approximately 30% higher than that of ordinary carbon steel. It forms a self-balancing system through rigid connections between corner fittings and side beams, reducing material usage by about 15%. The enclosure structure adopts a three-layer composite construction of "rock wool - air layer - aluminized zinc plate": the rock wool layer is 75-100 millimeters thick with a thermal conductivity of ≤0.040 W/(m·K), combined with a 5-millimeter air layer to suppress convective heat transfer. The overall heat transfer coefficient (U-value) is <0.5 W/(m²·K), effectively reducing condensation risks and extending the lifespan of the steel structure. The coating system uses a combination of "epoxy zinc-rich primer + polyurethane topcoat". The primer contains ≥80% zinc powder, and the topcoat is added with nano-silica particles, achieving a hardness of 3H grade. It passes a 1000-hour salt spray test (ASTM B117 standard) without red rust, equivalent to a 15-year protection cycle in coastal or industrial pollution environments, supporting a 25-year lifespan for the container body.
Application Scenarios and Advantages
Container-type mobile houses offer mobility, rapid assembly, and safety and durability: their transportation volume can be compressed to less than 50% of the original volume, and the air-break thermal design ensures sound and thermal insulation performance, supporting stacking and modular layouts, saving nearly 40% in single-set sea freight costs. Their application scenarios cover both temporary and permanent building fields: the foreign market is gradually shifting towards business offices, tourist villas, and other scenarios; domestically, the construction site and rail transit sectors are the main areas, with持续增长 (sustained growth) in demand for light steel structure modular houses. Compared to movable plank houses, container houses adopt an integral welded structure with insulation layers inside the walls, significantly improving wind resistance (less likely to be damaged in typhoon conditions). Installation takes only 15 minutes with pre-installed water and electricity, and furniture can be hoisted as a whole when moving. They have a lifespan of over 10 years, offering wind protection in winter, thermal insulation in summer, sound insulation close to that of buildings, and lower long-term usage costs.
Market Price Range
The price of basic export container panel houses (such as temporary office dormitories on construction sites) is approximately ¥200.0 per set, while the price of new photovoltaic panel container houses (including off-grid solar power generation systems) is approximately ¥600.0 per set. The price difference mainly stems from functional configurations and material grades.
