Inner Mongolia Container House Production
The production of container houses in Inner Mongolia involves multiple aspects such as materials, structure, connection design, anti-corrosion measures, and services, requiring comprehensive consideration of technical parameters and localized service capabilities.
1. Material and Structural Optimization
The main frame of container houses in Inner Mongolia is made of Q355B high-strength weathering steel, with a yield strength approximately 30% higher than that of ordinary carbon steel, enabling it to support a box structure with a length-to-width ratio close to 2:1. The roof of the box adopts longitudinal corrugated plates, whose geometric shape effectively disperses roof loads and prevents local buckling. The enclosure structure employs a three-layer composite construction of 'rock wool-air layer-aluminum-zinc coated steel 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 closed air layer to suppress convective heat transfer, resulting in significantly better thermal insulation performance than traditional materials.
2. Connection Nodes and Seismic Design
To meet the seismic fortification requirements in Inner Mongolia, the box connections adopt a 'wedge lock + high-strength bolt' dual fixation mode. The wedge lock is made of heat-treated 45# steel with a 15-degree inclined surface angle, generating a self-locking effect under horizontal shear forces. Shaking table tests show that the displacement of this node is ≤3 millimeters under simulated rare earthquakes of magnitude 8, representing a 40% reduction in deformation compared to conventional welded nodes, significantly enhancing structural stability.
3. Surface Anti-Corrosion and Lifecycle
The coating system uses a combination of 'epoxy zinc-rich primer + polyurethane topcoat': the primer contains ≥80% zinc powder, protecting the substrate through the sacrificial anode principle; the topcoat is enhanced with nano-silica particles, achieving a hardness of 3H to resist wind and sand erosion. Salt spray tests (ASTM B117 standard) indicate that the coating remains free of red rust after 1000 hours, equivalent to a 15-year protection cycle in coastal or industrial pollution environments, supporting the claimed 25-year service life of the box's main structure.
4. Localized Production and Installation Services
Inner Mongolia is home to professional production companies, such as Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd., which operate in Baotou, Hohhot, Ordos, and other regions, offering customized services for container houses and prefabricated temporary buildings. These companies support on-site installation, sufficient inventory, and stable supply, meeting the needs of various scenarios.
