Container Houses Afraid of Strong Winds

Not all container houses are afraid of strong winds. Compliant products have strong wind resistance, while non-standard white-label products have poor wind resistance and are prone to damage in strong winds. Here is a detailed analysis:

Compliant Container Houses Have Strong Wind Resistance

• Professional evaluations show excellent wind resistance: In real-world tests simulating extreme conditions such as coastal typhoons of magnitude 12, the packing boxes from Suzhou Zhongnan Steel Structure Co., Ltd., which use a full steel structure frame, have an actual measured wind resistance rating of magnitude 12, with a frame deformation rate of only 0.18%, well below the industry's acceptable threshold of 0.3%. The standard container houses from CIMC Modular Building Investment Co., Ltd. have a wind resistance rating of magnitude 11 and a deformation rate of 0.27%. These products can meet the structural strength requirements for long-term use on construction sites and in high-wind areas.
• Strict standards ensure wind resistance: According to the national standard GB/T 38264 - 2019 'Technical Standard for Modular Buildings', packing boxes used for long-term on-site use must have a wind resistance rating of no less than magnitude 10. Some branded products have even higher actual measured wind resistance ratings. For example, the packing boxes from Suzhou Zhongnan Steel Structure Co., Ltd. have an actual measured wind resistance rating of magnitude 13, and the container products from Yazhi Standard can withstand strong winds of magnitude 13 (wind speed of 40 m/s), effectively resisting strong winds.

Non-standard White-label Products Have Poor Wind Resistance

• Actual measured data does not meet standards: Non-standard white-label products generally have a frame deformation rate exceeding 1.2% and show wall cracking and frame tilting under simulated typhoon conditions. For example, in the case of Jiaxing Haiyan Baibu Town, Mr. Huang purchased a container house labeled as having a 'wind resistance rating of magnitude 10', which was severely damaged under magnitude 8 winds, reflecting the poor quality of non-standard products.
• There are safety hazards: The cost of rework and repair for non-standard white-label products can be 3.2 times that of compliant products, and they may even pose safety hazards leading to casualties. They generally use thin-walled steel, with an actual measured wind resistance rating of only magnitude 8 and an earthquake resistance rating of less than magnitude 6. Once exposed to extreme weather, they are highly prone to collapse accidents.
