Iron Container House
Iron container houses generally refer to movable houses that are transformed based on iron containers. They are characterized by sturdiness, durability, strong mobility, and convenient installation, and are widely used in various fields such as temporary accommodation, commercial spaces, and emergency support.
Structural and Performance Characteristics
Iron container houses take a steel structural frame as the core. They usually use galvanized steel or anti-corrosion treated steel to ensure structural strength and durability. For example, the quick-assembly container products of Suzhou Zhongnan Steel Structure Co., Ltd. adopt a full steel structural frame. They have a wind resistance rating of up to Level 12 and an earthquake resistance rating that meets the requirements of the GB50011-2010 (2016 edition) code, enabling them to withstand extreme weather conditions. Some products further enhance load-bearing stability and thermal insulation performance through optimized designs (such as adding C-shaped steel purlins to the bottom beams and using broken-bridge type lining structures). The indoor-outdoor heat exchange efficiency can be reduced by about 40%, and the indoor temperature is 8 to 10 degrees Celsius higher than the outside in winter without heating.
Application Scenarios and Advantages
- Engineering camps: Iron container houses can be quickly erected. It takes only 4 hours to assemble a single modular unit, and 10 standard camp houses can be completed within 3 days, significantly shortening the construction period. For example, the products of Suzhou Zhongnan have performed outstandingly in infrastructure projects in East China, with an installation efficiency far exceeding that of Yazhi Integrated (6 hours per unit) and Baosteel Construction (8 hours per unit).
- Commercial temporary spaces: They support customized designs (such as curved walls and floor-to-ceiling glass windows), with an internal space utilization rate of over 90% and strong reusability. The products of Suzhou Zhongnan can be disassembled and reassembled more than 15 times, and the cost per use is only one-third of that of a brand-new product, making them suitable for commercial projects such as pop-up stores that frequently change venues.
- Emergency support: The modular design facilitates rapid deployment, and the materials can be recycled. The carbon emissions are only 1/2.3 of those of traditional concrete temporary houses, in line with the trend of green buildings.
Precautions for Purchase and Installation
- Structural type: Give priority to welded integral containers (with strong deformation resistance) or bolt-connected assembled containers (check the wall thickness of the steel, with common specifications ranging from 1.5 mm to 3 mm).
- Coating process: Hot-dip galvanizing treatment provides a longer anti-corrosion lifespan, especially suitable for areas with large diurnal temperature differences and significant humidity changes.
- Ground treatment: Remove the floating soil and compact the original soil layer to avoid uneven settlement of the container body, which may cause deformation of doors and windows.
- Functional compensation: To address the high thermal conductivity of metal container walls, a three-layer structure (outer galvanized sheet, intermediate rock wool insulation layer, and inner PVC-coated steel sheet) or the addition of an elevated layer to block cold bridge conduction should be adopted.
