Xi'an Rental Container House

The main materials of rental container houses in Xi'an are steel structures paired with corrugated sheets or color-coated steel plates, with some high-end products using CORTEN weathering steel. The following provides an introduction from three aspects: material characteristics, structural composition, and application scenarios:

1. Steel Structure: Core Load-Bearing and Safety Assurance
The framework of container houses adopts high-strength steel structures, primarily made of galvanized steel or CORTEN weathering steel.

• Galvanized Steel: Treated through hot-dip galvanizing, a dense zinc layer forms on the surface, providing excellent corrosion resistance and extending the service life to over 20 years. It is strong yet lightweight, capable of withstanding winds of force 8 or above and seismic impacts, ensuring stability in harsh environments.
• CORTEN Weathering Steel: A special alloy steel that forms a dense oxide layer in natural environments by adding elements such as copper and chromium, eliminating the need for additional painting for long-term rust prevention. This material is commonly used in high-end container houses, balancing durability and aesthetics, suitable for coastal or high-humidity areas.

2. Enclosure Materials: Balancing Functionality and Economy
Walls and roofs use corrugated sheets or color-coated steel plates to achieve a balance between sound insulation, thermal insulation, and cost control.

• Corrugated Sheets: Made from color-coated steel plates as the base material, shaped into a wavy structure through profiling, enhancing panel rigidity. Its air-gap thermal insulation design effectively blocks heat transfer, keeping indoor temperatures 5-8°C lower in summer and improving winter insulation by over 30%. Additionally, the corrugated structure absorbs some sound waves, reducing noise interference.
• Color-Coated Steel Plates: Composed of two metal layers with an intermediate polyurethane or rock wool sandwich layer, typically 50-100mm thick. Polyurethane sandwich panels have a thermal conductivity as low as 0.024W/(m·K), offering better thermal insulation than traditional brick walls; rock wool sandwich panels provide Class A fire resistance, meeting fire safety regulations.

3. Structural Optimization: Adapting to Diverse Needs
Container houses adopt a modular design with standard dimensions of 3m x 6m or 6m x 2.4m, allowing for expansion through splicing.

• Mobility: The combination of steel structures and lightweight enclosure materials reduces the house's self-weight to 2-3 tons, facilitating lifting and transportation.
• Rapid Deployment: Factory-prefabricated components are assembled on-site without the need for foundation treatment, enabling single-unit installation within 4 hours and significantly shortening construction cycles.
• Customization: Supports customization of exterior styling, interior layout, and functional modules, such as adding glass curtain walls, solar panels, or intelligent security systems, to meet various scenarios including office, residential, and commercial uses.
