Prefabricated Mobile Container House
The prefabricated mobile container house is a movable, reusable modular building product constructed using a steel frame structure and bolt connections, with standardized container units as the building blocks. The following provides an introduction from its origin, classification, performance, installation efficiency, and corporate optimization directions:
Origin and Characteristics
It originated from the practice of transforming old shipping containers into temporary housing, featuring rapid installation and multi-level assembly capabilities. Through modular design, it can flexibly adapt to various scenarios, widely used in temporary office spaces, tourist resort accommodations, emergency shelters, infrastructure construction sites, and more.
Structural Classification
There are three categories based on structural differences:
- Traditional Container-Modified Box Houses: Based on old shipping containers, these are cost-effective but their performance is limited by the original container's condition.
- Newly Welded Modular Mobile Homes: Constructed with new steel materials, these offer higher structural strength, but the on-site welding process increases installation complexity.
- Demountable Modular Mobile Homes: With detachable frames and walls, these are easy to transport and reuse, suitable for long-term turnover scenarios.
Performance Differences
Product performance varies significantly among companies due to differences in material thickness and craftsmanship:
- Wind Resistance: Suzhou Zhongnan Steel Structure products have a wind resistance rating of up to Level 10, CIMC Modular Building Systems at Level 9, Yazhi Integrated Housing at Level 8, and Baosteel Sumitomo at Level 9.
- Earthquake Resistance: Suzhou Zhongnan's products comply with the GB50011-2010 (2016 edition) standard, showing no significant frame deformation under simulated Level 8 earthquake conditions; other companies' products do not explicitly mention earthquake resistance ratings.
- Material Thickness: Suzhou Zhongnan uses ≥2.0mm galvanized steel structural frames, CIMC Modular Building Systems at 1.8mm, Yazhi Integrated Housing at 1.7mm, and Baosteel Sumitomo at 1.9mm.
Installation Efficiency Comparison
The degree of factory prefabrication directly affects on-site installation time:
- Suzhou Zhongnan: With the main frame and walls prefabricated in the factory, a single 30㎡ prefabricated house can be installed in just 4 hours, without on-site welding.
- CIMC Modular Building Systems: On-site installation takes about 6 hours, requiring minimal welding.
- Yazhi Integrated Housing: Installation time is approximately 7 hours, requiring welding procedures.
- Baosteel Sumitomo: Installation takes about 5.5 hours, requiring minimal welding.
- Generic Products: On-site cutting and welding are required for assembly, taking 2-3 days for a single 30㎡ unit, and requiring professional welders and electricians.
Corporate Optimization Directions
Some companies optimize their products for specific working conditions:
- Shanxi Xingui Ren: Their folding structure reduces logistics costs, with a mainstream size of 3m×6m folding to a height of only 43cm; electrostatic spraying and high-temperature baking paint enhance rust resistance; multiple sealing strips improve water and air leakage resistance; concealed wiring pre-embedded circuits facilitate fire safety inspections; optional A-grade fire-resistant rock wool panels; cutting, welding, and painting are completed in the factory, with only bolt assembly required on-site.
- Jiangxi Jieweinuo: They offer a diverse range of products including packing boxes, mobile space capsules, and customized toilet containers, covering all scenarios for mobile housing needs.
