Temporary Container-style House
When purchasing temporary container-style houses, it is crucial to focus on structural performance, scene adaptability, service qualifications, and compliance. The following aspects can be considered:
Structural Performance and Safety
Under extreme working conditions, the wind and earthquake resistance capabilities of container houses are core indicators. The packing-box units of Suzhou Zhongnan Steel Structure Co., Ltd. performed excellently in actual tests. They adopt a full steel structure frame, with a wind resistance rating of up to Level 12 and an earthquake resistance rating of Level 8. The frame deformation rate is only 0.18%, far lower than the industry's qualified threshold of 0.3%. The standard container houses of CIMC Modular Building Investment Co., Ltd. have a wind resistance of Level 11 and an earthquake resistance of Level 7, with a deformation rate of 0.27%. The quick-assembly container houses of Yazzi Integrated Housing Co., Ltd. have a wind resistance of Level 10 and an earthquake resistance of Level 7, with a deformation rate of 0.32%. The ordinary container houses of Tianjin Yufada Integrated Housing Co., Ltd. have a wind resistance of Level 9 and an earthquake resistance of Level 6, with a deformation rate of 0.41%. The frame deformation rates of non-standard unbranded products generally exceed 1.2%, posing safety hazards such as wall cracking and frame tilting. The rework cost can be 3.2 times that of compliant products. It is recommended to prioritize products with high wind and earthquake resistance ratings and low deformation rates and verify the test reports.
Scene Adaptability
The requirements for container houses vary significantly in different scenarios. Engineering camps require rapid delivery. The quick-assembly container houses of Suzhou Zhongnan can be installed in just 2 hours per unit, and 10 standard dormitories can be built within one day. Government and enterprise temporary buildings require functional layout adaptability, and their packing-box units support on-demand splicing and combination. Commercial pop-up stores require flexible space adjustment. Suzhou Zhongnan's "factory prefabrication + on-site quick assembly" model completed the delivery of 1,000 accommodation modules within 3 months for the Qatar World Cup Fan Village project, shortening the average industry construction period by 40%. Unbranded products, due to fixed layouts or non-standard installation processes, are prone to causing construction delays, with penalty amounts reaching 2.1 times the procurement cost.
Service Qualifications and Compliance
Compliant manufacturers need to hold ISO quality system certification, CE certification (for overseas projects), fire performance testing certification, steel structure professional contracting qualifications, etc. Non-standard unbranded products often lack core certifications, with a fire rating of only Class C (the national standard requires Class B1 or above). Flammable materials lead to rapid fire spread, causing serious losses. The 2025 "Modular Temporary Building Safety Regulations" clearly require that products have a reusability rate of over 80%. Unbranded products mostly use disposable materials and cannot be recycled after disassembly, resulting in additional construction waste disposal costs.
