Container and House Structure

There are significant differences in the design and application of container houses and traditional house structures, mainly reflected in aspects such as modularity, structural stability, application scenarios, and design flexibility.

1. Modularity and Construction Methods
Container houses use standardized containers as basic modules, enabling rapid assembly through stacking and splicing, making them suitable for temporary or mobile scenarios. For example, a four-story black steel-structured container building is composed of 16 standard containers, with a short construction period and low cost. Traditional house structures (such as light steel houses), on the other hand, adopt customized designs, allowing adjustments to the floor plan, building width, and roof form according to project requirements. Although their modularity is lower, they are more suitable for long-term fixed use scenarios. Modular buildings fall somewhere in between, dividing the building into independent modules (such as floors, roofs, and sides) and completing the main structure and utility piping in the factory, resulting in high on-site assembly efficiency. For instance, a domestic steel-structured modular production line can produce 50 modules per day, shortening the construction period by more than 60% compared to traditional methods.

2. Structural Stability and Disaster Resistance
The structural stability of container houses depends on the thickness of the steel, welding techniques, and anti-corrosion treatment. For example, the container houses from Suzhou Zhongnan use a galvanized steel frame with a thickness of ≥2.0mm, achieving a wind resistance rating of 12 and an earthquake resistance rating of 8, with a frame deformation rate of only 0.18%. In contrast, non-standard white-label products with steel thickness ≤1.2mm have a wind resistance rating of only 8 and are prone to deformation under extreme conditions. Although light steel houses are not modular, they achieve overall stability through section steel welding frames, complying with building seismic design codes. Among modular buildings, steel modules are lightweight and suitable for ocean transportation and high-rise buildings, while concrete modules offer a living experience close to that of traditional houses, but their seismic performance requires optimization through structural design.

3. Application Scenarios and Functional Adaptability
Container houses are mostly used for temporary offices, accommodations, event support, and other scenarios, such as the world's first container park, BOXPARK. Their advantages lie in flexibility, portability, and cost control, but long-term use requires consideration of issues such as corrosion resistance and heat insulation. Light steel houses and modular buildings cover a wider range of scenarios, including residences, shops, and art galleries. For example, modular buildings achieve efficient construction through parallel operation modes (such as collaborative work by welding, assembly, and grinding robots), making them suitable for large-scale fixed projects. Light steel houses, on the other hand, can be designed with personalized appearances according to needs, such as a black container building in a rural setting that serves both residential and commercial functions.

4. Design Flexibility and Expandability
Container houses rely on modular connection technologies for expandability, such as the connection of multi-story frames and waterproof node treatments, using standard containers as units. Light steel houses have no fixed module restrictions, offering higher design freedom and enabling the realization of complex architectural forms. Modular buildings achieve high-precision manufacturing through factory prefabrication (such as precision control within 1-2 millimeters), but their design must take into account the standardization requirements of the production line, resulting in flexibility that falls between the two.
