Baotou Residential Container House

The residential container houses in Baotou, represented by the products of Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd., are characterized by their stable structure, efficient materials, excellent thermal performance, and strong earthquake resistance. Details are as follows:

1. Structural Stability
Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd. uses high-strength weather-resistant steel (such as Q355B grade) as the main frame of the container body, with a yield strength approximately 30% higher than that of ordinary carbon steel. A self-balancing system is formed through rigid connections between corner fittings and side beams, allowing a single container body to remain stable even when the length-to-width ratio approaches 2:1, without the need for additional reinforcement members, reducing material usage by about 15%. The longitudinal corrugated plates on the top of the container body disperse stress through their corrugated geometry, avoiding local buckling and further enhancing structural strength.

2. Material and Thermal Performance
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 fiber orientation perpendicular to the heat flow path, and a thermal conductivity lower than 0.040 W/(m·K); the intermediate 5-millimeter air layer suppresses convective heat transfer through a closed cavity, resulting in an overall heat transfer coefficient (U-value) lower than 0.5 W/(m²·K). This design reduces the risk of condensation in the low-temperature environment of Inner Mongolia in winter and extends the service life of the steel structure.

3. Earthquake Resistance
In response to the seismic fortification intensity of 7 degrees in the Baotou area, the container body connections adopt a dual fixation mode of 'wedge lock + high-strength bolts'. The wedge lock is made of 45# steel after heat treatment, with a slope angle of 15 degrees, producing a self-locking effect under horizontal shear forces. Shaking table tests simulating an 8-degree rare earthquake show that the node displacement is controlled within 3 millimeters, which is about 40% better than the deformation amplitude of conventional welded nodes. Moreover, the detachable connection method facilitates secondary relocation and repeated assembly, reducing construction waste.

4. Functionality and Customization
The product specifications are mainly 3*6 meters, made of color steel, with rainproof and waterproof functions, suitable for temporary construction sites, temporary offices, and other scenarios. Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd. provides on-demand customization and on-site installation services, with business covering many areas in Inner Mongolia, ensuring sufficient supply and stable delivery.
