Container House Manufacturing

Container house manufacturing takes standardization and modularization as its core, achieving efficient construction through industrial production processes. Its design, materials, processes, and production modes all revolve around enhancing structural stability, installation efficiency, and scenario adaptability.

1. Structural Design: Modular and Self-Balancing System

Container houses use standard containers as carriers, which are transformed into independent office or living units. Common sizes are 20-foot and 40-foot, supporting single-container use or multi-container assembly. The core design logic is modular and self-balancing:

• Structural Stability: High-strength weather-resistant steel (such as Q355B grade) is used as the main frame, 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, reducing the need for external supports. For example, the longitudinal corrugated plates on the top of the container disperse stress through their corrugated geometry, avoiding local buckling and reducing material usage by 15%.
• Expandability: Side or end expansion modules can be added to the container, increasing usable area by 30%-50% when deployed, meeting the space needs of long-term on-site offices.

2. Material Selection: Composite Construction and Weather Resistance

The enclosure structure adopts a three-layer composite construction of 'rock wool-air layer-aluminum-zinc plate', balancing thermal insulation and durability:

• Rock Wool Layer: With a thickness of 75-100 mm, the fibers are arranged perpendicular to the heat flow path, with a thermal conductivity below 0.040 W/(m·K), effectively suppressing condensation risks.
• Air Layer: A 5 mm closed air cavity suppresses convective heat transfer, with an overall heat transfer coefficient (U-value) below 0.5 W/(m²·K), suitable for low-temperature environments like Inner Mongolia.
• Anti-Corrosion Coating: A combination of epoxy zinc-rich primer (zinc powder content ≥80%) and polyurethane topcoat (containing nano-silica particles, hardness 3H) is used, showing no red rust after 1000 hours of salt spray testing, with a main structure lifespan of 25 years.

3. Production Process: Industrialization and Standardization

The manufacturing process covers cutting, processing, structural assembly, welding, anti-corrosion treatment, enclosure installation, and internal functional module construction, achieving coordinated progress through workstation division and standardized operations:

• Precision Control: CNC bending machines control the bending angle error of door frames within ±0.5 degrees. EPDM rubber seals have better weather resistance than ordinary silicone seals, with a service life exceeding 5 years.
• Installation Efficiency: The design of foldable packing containers allows a single set to be deployed in ≤30 minutes, suitable for frequent relocation scenarios like exploration teams. Assembled houses use light steel frames combined with color-coated steel plates for on-site modular assembly, flexibly expanding functional areas.

4. Scenario Adaptation: From Temporary to Permanent

Container houses have covered scenarios such as engineering camps, commercial pop-ups, government and enterprise temporary buildings, and data centers, with advantages including:

• Rapid Deployment: The construction period for modular data centers is 50% shorter than traditional methods. For example, the Malaysia 2312 project completed a 60MW IT load capacity in just 10 months.
• Cost Control: Factory standardized production reduces steel waste to 3%-5% (8%-12% on traditional construction sites) and reduces foundation material consumption by 60%-70%.
