Container Integrated Housing Materials
The main materials for container integrated housing include steel, aluminum alloy, glass, plastic, and various composite panels, with specific material selection closely related to the housing structure design, functional requirements, and usage environment.
Steel is the core structural material for container integrated housing, typically using high-strength weather-resistant steel (such as Q355B grade) as the main frame of the container body. This type of steel has a yield strength approximately 30% higher than that of ordinary carbon steel, forming a self-balancing system through rigid connections between corner fittings and edge beams, reducing the need for additional reinforcement and lowering material usage. For example, Yiqi Company has optimized steel selection and modular design, enabling a single container body to maintain structural stability even when the length-to-width ratio approaches 2:1. Additionally, hot-dip galvanized cold-formed steel is also commonly used in frame structures, offering excellent rust and corrosion resistance suitable for long-term outdoor exposure.
Aluminum alloy materials are primarily used for doors, windows, and decorative components, characterized by their lightweight, aesthetic appeal, and corrosion resistance, while also providing good thermal insulation performance to enhance housing comfort. The sealed design of aluminum alloy doors and windows effectively resists wind and sand erosion, extending their service life.
Glass materials are widely used in doors, windows, and observation windows, offering high transparency and reflectivity to increase indoor lighting and field of view. Some high-end products use tempered glass or insulated glass to further enhance thermal and sound insulation performance, meeting the needs of different scenarios.
Plastic products are mostly used as auxiliary components in container housing, such as plastic pipes and panels. These materials are lightweight, easy to process, and cost-effective, suitable for manufacturing non-load-bearing structures like interior partitions or decorative panels.
Composite panels are key materials for the enclosure structure of container housing, with common types including a three-layer composite structure of "rock wool-air layer-aluminized zinc plate". The rock wool layer is controlled at a thickness of 75-100 millimeters, with a thermal conductivity below 0.040 W/(m·K), combined with a 5-millimeter air layer to suppress convective heat transfer, resulting in an overall heat transfer coefficient below 0.5 W/(m²·K), effectively reducing condensation risk. Additionally, polyurethane sandwich panels are also commonly used for walls and roofs, offering both thermal insulation and fire resistance.
