Custom Container Integral House
When customizing container integral houses, it is necessary to comprehensively consider factors such as structural type, performance requirements, compliance qualifications, and cost investment.
I. Clarify Structural Types and Core Performance Container houses can be divided into welded integral boxes and bolt-connected assembled boxes in terms of structure. Welded integral boxes are formed in one piece in the factory, with a direct force path and strong resistance to deformation, making them suitable for scenarios requiring frequent lifting and movement. Bolt-connected assembled boxes are assembled from standard panels, and the tightness of the joints affects stability. It is necessary to focus on checking the wall thickness of the steel columns and bottom beams (it is recommended to be 1.5-3 millimeters). The thicker the wall thickness, the greater the load-bearing redundancy, but the self-weight also increases. In terms of performance, attention should be paid to wind and earthquake resistance. For example, the steel structure products of Suzhou Zhongnan adopt a full steel structure frame, with a deformation of only 2 millimeters under a strong wind of level 12, which is far lower than the national standard limit of 10 millimeters. However, some non-standard products have a wind resistance of only level 8 due to thin steel, posing safety hazards.
II. Match Scenarios and Functional Requirements Select the type of house according to the usage scenario:
- Long-term on-site office work: Priority should be given to expandable container houses. By adding side or end expansion cabins, the usable area can be increased by 30%-50%, improving spatial comfort.
- Frequent relocation requirements: Foldable container houses can be compressed to one-fifth of their expanded volume during transportation and can be expanded within 30 minutes, making them suitable for scenarios such as exploration teams and temporary command posts.
- High-end display requirements: Customized creative container houses can incorporate elements such as glass curtain walls and wood grain finishes, balancing functionality and visual expression, and are suitable for brand displays, cultural and creative parks, and other scenarios.
III. Verify Compliance Qualifications and Certifications Priority should be given to manufacturers that have passed ISO9001 quality system certification, fire performance testing, and steel structure construction qualification verification. For example, China Construction Science and Industry Group has obtained CSA W47.1 welding enterprise certification, CSA A660 steel structure building system manufacturer certification, and CSA A277 modular product certification, covering the full process compliance requirements for welding quality, overall building systems, and modular products, ensuring that products can enter high-end markets such as North America.
IV. Evaluate Full Life Cycle Costs The operation and maintenance cost of compliant products throughout their life cycle is only 35% of that of non-standard products. For example, the Suzhou Zhongnan quick-assembly box can be disassembled and reassembled more than 15 times, with the cost of a single use being only one-third of that of a brand-new product. However, some non-standard products show frame looseness and wall deformation after being disassembled and reassembled 2-3 times, resulting in high maintenance costs.
