Baotou Assembled Container House

Baotou assembled container houses typically use materials such as color-coated steel, achieving a combination of functionality and environmental protection through modular design, structural optimization, anti-corrosion and thermal insulation treatments, and environmental measures. Details are as follows:

Materials and Structure

The main body of Baotou assembled container houses often uses a combination of galvanized steel frames and rock wool sandwich panels, with some products using color-coated steel as the outer shell and inner core material. Taking Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd. as an example, its container bodies complete the main structure, interior and exterior wall decoration, and pipeline embedding in the factory, integrating walls, roofs, and floors into rigid units. This fully prefabricated approach requires only lifting and joint treatment for on-site installation, reducing construction errors from the centimeter level to the millimeter level. Residents directly experience higher spatial squareness, and the standardization of door and window openings and pipeline interfaces reduces the need for later modifications.

Structural Optimization and Anti-Corrosion Treatment

The traditional container's bottom frame has large spacing between longitudinal beams, which can lead to insufficient floor stiffness when used directly as living space. Relevant enterprises in Baotou adopt the method of adding C-shaped steel purlins between the bottom beams to evenly distribute the load to each main beam, enabling the container body to maintain structural stability even when stacked three layers high. After shot blasting and rust removal, the container body surface is sprayed with a zinc-rich primer and a polyurethane topcoat. This protective system allows the steel to maintain an effective service life of more than 15 years in the northwest's windy and sandy environment with large temperature differences.

Thermal Insulation Performance

To address the cold and heat bridge effect of the metal container walls, an improved solution is to use a broken-bridge lining structure, which involves filling hard polyurethane foam between the steel frame and the interior wall panel and adding rubber thermal insulation pads at the connections of the keels, reducing the heat exchange efficiency between the interior and exterior of the container by about 40%. For camp dormitory projects, this treatment can raise the indoor temperature by 8 to 10 degrees Celsius compared to the outside in winter without heating, thereby reducing reliance on heating equipment and energy consumption.

Environmental Protection and Recycling

The core value of container houses lies in the full life-cycle recycling of their materials. Each standard 20-foot container consumes about 1.2 tons of steel. If a one-time poured concrete temporary house is used, the carbon emissions from the concrete and steel required for the same area are 2.3 times that of a container house. More critically, when the camp is relocated or the project ends, the container house can be lifted and moved to a new site as a whole, with the disassembly and assembly loss rate controlled within 5%.
