Steel Container House Structure Diagram
Currently, there is no specific structural diagram directly provided for steel container houses, but we can roughly understand their structural composition based on the structural characteristics of expandable residential container houses.

Main Frame
The main frame of a steel container house typically adopts a steel skeleton structure, with galvanized pipes as the primary material. Galvanized pipes have good corrosion resistance and strength, providing stable support for the entire house. This steel skeleton not only forms the basic outline of the house but also bears various loads during use, such as the weight generated by human activities and equipment placement. Structurally, the steel skeleton is combined with beams and columns in the middle rooms, which further enhance the overall stability of the house, ensuring structural integrity in various environments.
Wall Structure
Walls are an important part of a house. The walls of a steel container house generally use sandwich-structured thermal insulation sandwich panels. These sandwich panels are usually composed of two layers of metal panels and an intermediate thermal insulation material, which can be polystyrene, rock wool, etc. The sandwich-structured walls not only have good thermal insulation performance, effectively blocking the transfer of external heat and maintaining stable indoor temperatures but also have a certain soundproofing effect, providing a quiet and comfortable living environment for occupants.
Floor and Roof Structure
The floor adopts a multi-layer structure, including a base plate, floor leather, and bottom cotton strips. The base plate provides basic support for the entire floor, the floor leather adds to the aesthetics and comfort of the floor, and the bottom cotton strips can provide some cushioning and thermal insulation. The roof structure usually consists of a ceiling and a thermal insulation layer. The ceiling serves a decorative and protective function for the roof structure, while the thermal insulation layer further enhances the thermal insulation performance of the house, preventing indoor heat from dissipating through the roof.
Door and Window Structure
Doors and windows use double-glazed laminated glass, which has good soundproofing, thermal insulation, and safety performance. The double-layer structure can effectively block the entry of external noise while reducing heat transfer, improving the energy efficiency of the house. When subjected to external impact, the glass fragments of laminated glass will stick to the film and not splatter everywhere, thus ensuring the safety of occupants.
