Baotou Container House
Baotou container houses exhibit significant features in terms of materials, structure, functionality, and services, integrating innovative design with sustainable development concepts.
Material selection emphasizes strength and durability. The main frame is constructed from high-strength weather-resistant steel (such as Q355B grade), with a yield strength approximately 30% higher than that of ordinary carbon steel. Even when the length-to-width ratio of a single container approaches 2:1, it can still form a self-balancing system through rigid connections between corner fittings and side beams, reducing the need for additional reinforcement and lowering material usage by about 15%. The enclosure structure adopts a three-layer composite construction of 'rock wool-air layer-aluminum-zinc coated steel plate'. The rock wool layer, with a thickness of 75-100 millimeters, has a thermal conductivity below 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 below 0.5 W/(m²·K), effectively reducing the risk of winter condensation and extending the service life of the steel structure.
Structural design emphasizes earthquake resistance and modularity. Given the seismic fortification intensity of 7 degrees in the Inner Mongolia region, the container connections employ a dual-fixing mode of 'wedge lock + high-strength bolts'. The wedge lock has a 15-degree inclined surface that generates a self-locking effect under horizontal shear forces. In simulated 8-degree rare earthquake tests, displacement is controlled within 3 millimeters, outperforming conventional welded joints by about 40% in terms of deformation amplitude. The modular design supports vertical stacking of multiple containers, with columns made of 6-millimeter thick square steel and reinforced with stiffeners, increasing overall compressive strength by about 50%. Standardized integration of water and electricity pipeline interfaces within the container chassis, along with quick-connect designs, reduces installation errors.
Functional configuration balances environmental protection and adaptability. The coating system uses a combination of 'epoxy zinc-rich primer + polyurethane topcoat'. The primer contains over 80% zinc powder, protecting the base metal through sacrificial anode principles. The topcoat, enhanced with nano-silica particles, achieves a hardness of 3H and shows no red rust after 1000 hours of salt spray testing, supporting a 25-year service life for the container's main structure. Tailored to northern climate characteristics, the product offers excellent thermal insulation performance with low thermal conductivity of the core material. In Baotou's winter environment of minus 20°C, it maintains a comfortable temperature without the need for additional high-power heating equipment, while the panels remain non-shrinking and non-brittle in low temperatures.
Service model provides full-process support. The enterprise integrates research and development, production, and sales, supporting on-demand customization and on-site installation, with stable supply and short delivery cycles (e.g., 7-8 days). Leasing services are flexible, allowing customers to choose durations based on usage needs and enjoy installation and maintenance support, making them particularly suitable for short-term housing scenarios such as municipal emergency repairs, exhibition setups, and disaster relief.
