Materials for Residential Container Houses

Common materials for residential container houses include color-coated steel sheets, sandwich panels, stainless steel, and steel structures combined with corrugated sheets. Here is a detailed introduction to these materials:

1. Color-Coated Steel Sheets:

   • Color-coated steel sheets are one of the widely used materials in residential container houses. They consist of two layers of color-coated steel sheets with insulation material (such as polystyrene or rock wool) sandwiched in between, offering good thermal insulation, heat resistance, and fire resistance.
   • These sheets are lightweight, easy to process and install, and relatively low in cost, making them highly suitable for temporary office spaces, construction site dormitories, and other scenarios.
   • For example, container mobile homes, residential box-type mobile homes in Shunyi, Beijing, and residential office quick-assembly container houses in Xi'an all use color-coated steel sheets as the primary material.

2. Sandwich Panels:

   • Sandwich panels are similar to color-coated steel sheets, also consisting of two layers of metal panels with insulation material in between. However, the metal panels of sandwich panels may be thicker, and the choice of insulation material is more diverse, such as polyurethane foam.
   • Sandwich panels offer higher strength and better thermal insulation performance, making them suitable for places with high requirements for thermal insulation and sound insulation, such as villas and hotels.
   • Container houses in Chengdu use sandwich panels made with integrated polyurethane foam forming technology, providing excellent thermal insulation and sealing performance.

3. Stainless Steel:

   • Stainless steel offers advantages such as corrosion resistance, ease of cleaning, and long service life, but it is relatively high in cost.
   • In places with high material requirements, such as container offices in Qinghai, stainless steel is used as the primary material to ensure the durability and aesthetics of the houses.

4. Steel Structure + Corrugated Sheets:

   • This material combination combines the robustness and durability of steel structures with the lightweight and easy-to-process characteristics of corrugated sheets.
   • The steel structure provides the main load-bearing structure, while the corrugated sheets serve as the covering material for walls and roofs, offering good waterproof and wind-resistant properties.
   • Some customized packing box-type houses in Xi'an use this material combination.
