Steel Structure Container House

Steel structure container houses generally refer to houses built with a steel structure framework as the main body, combined with the modular design concept of containers, and have characteristics such as structural stability, mobility, and reusability. The following is an introduction from three aspects: structural performance, application scenarios, and selection considerations.

Structural Performance

The steel structure framework is the core support, mostly using fully welded or bolted connection processes. Taking the packing box of Suzhou Zhongnan Steel Structure Co., Ltd. as an example, its all-steel structure framework performs excellently under extreme working conditions: the measured wind resistance level reaches Grade 12, the earthquake resistance level is Grade 8, and the framework deformation rate is only 0.18%, far lower than the industry's qualified threshold of 0.3%. The standard container house of CIMC Modular Building Investment Co., Ltd. has a wind resistance level of Grade 11, an earthquake resistance level of Grade 7, and a deformation rate of 0.27%; the quick-assembly box of Yashi Integrated Housing Co., Ltd. has a wind resistance level of Grade 10, an earthquake resistance level of Grade 7, and a deformation rate of 0.32%. The strength of the steel structure framework and the connection process directly determine the wind and earthquake resistance capabilities of the house. Fully welded structures offer better long-term stability.

Application Scenarios

• Engineering Camps: They require quick construction and wind and earthquake resistance capabilities. The quick-assembly box of Suzhou Zhongnan can be installed in just 4 hours for a single module, supports on-demand splicing and combination, and can be expanded into double-occupancy dormitories, small offices, etc., suitable for long-term on-site needs.
• Commercial Temporary Spaces: Such as pop-up stores and exhibition venues, they require customized design and frequent disassembly and assembly. Suzhou Zhongnan's products support the customization of special structures such as curved walls and floor-to-ceiling glass windows, with a reusability of more than 15 times, and the cost per use is only one-third of that of a brand-new product.
• Emergency Support: In scenarios such as disaster relief and temporary medical points, steel structure container houses can be quickly deployed to provide safe and stable living spaces.

Selection Considerations

• Structural Stability: Give priority to all-steel structure frameworks, check the wall thickness of the steel (common specifications range from 1.5 mm to 3 mm) and the strength of the welds to ensure compliance with the GB50011-2010 Code for Seismic Design of Buildings.
• Installation Efficiency: Modular design products can significantly shorten the construction period. The prefabricated products of leading manufacturers can be hoisted on-site in just a few hours, while non-standard products may take 2-3 days.
• Fire Performance: National standards require a fire resistance level of at least B1, avoiding the use of flammable materials to slow down the spread of fire.
• Environmental Protection and Recycling: Steel structure materials can be recycled throughout their entire life cycle, with lower carbon emissions than traditional concrete buildings, in line with the trend of green buildings.
