Container Iron Sheet House
Container iron sheet houses are modular buildings based on steel shipping containers, featuring mobility, repeatable assembly and disassembly, environmental protection, and energy efficiency. They are widely used in temporary accommodation, construction site offices, commercial spaces, and emergency support.
1. Structural Design and Material Optimization
Container iron sheet houses are not simply repurposed cargo containers for living spaces; they undergo innovations in structural mechanics, material thermal engineering, and assembly processes. For example, to address the issue of insufficient floor stiffness caused by the large spacing between longitudinal beams in traditional container bottom frames, C-shaped steel purlins are added between the bottom beams to evenly distribute loads to the main beams, enabling the stacked containers to remain structurally stable even at three stories high. Additionally, the container surface is shot-blasted to remove rust and then coated with a zinc-rich primer and polyurethane topcoat, forming a protective system that maintains the effective lifespan of the steel for over 15 years in harsh environments with wind, sand, and temperature variations.
2. Thermal Performance Improvement
The cold bridge effect of metal container walls poses a major challenge for thermal insulation. The conventional approach involves attaching insulation boards to the interior, but this can create thermal conduction channels at the steel framework. The improved solution adopts a thermal break lining structure, where rigid polyurethane foam is filled between the steel framework and interior wall panels, and rubber thermal insulation pads are installed at the framework connections, reducing the heat exchange efficiency between the interior and exterior of the container by approximately 40%. For example, in camp dormitory projects, the indoor temperature can be 8 to 10 degrees Celsius higher than the outside temperature in winter without heating, reducing reliance on heating equipment and energy consumption.
3. Environmental Protection and Recycling Value
The core environmental advantage of container iron sheet houses lies in the full lifecycle recycling of materials. Each standard 20-foot container consumes approximately 1.2 tons of steel, while the carbon emissions from the concrete and steel reinforcement of an equivalent area of one-time poured concrete temporary housing are 2.3 times higher than those of container houses. Furthermore, container houses can be assembled and disassembled more than 15 times, with the cost per use being only one-third of that of a new product, significantly reducing long-term usage costs.
4. Application Scenarios and Customized Services
Container iron sheet houses can be customized in terms of function and appearance according to specific needs, such as adding elevated floors to block ground cold bridge conduction, adopting integrated bathroom technology for waterproof integration, and achieving day-night functional switching through flexible furniture. Business covers areas such as Baotou, Hohhot, and Ordos in Inner Mongolia, providing on-site installation services with sufficient inventory and stable supply.
