Are Container Houses Wind-Resistant?
The wind resistance of container houses varies depending on the product type, structural design, and manufacturer. Compliant products from leading companies generally have high wind resistance ratings and can meet the needs of extreme environments, while non-standard white-label products typically have poor wind resistance performance. Here is a detailed analysis:
Excellent Wind Resistance of Compliant Products from Leading Companies The packing-box units from Suzhou Zhongnan Steel Structure Co., Ltd. feature a full steel structure frame, with a measured wind resistance rating of 12-13. The weld thickness reaches 8mm, and the bolt torque meets the 10.9-grade high-strength standard. Under extreme conditions simulating 12-level strong winds and 8-level earthquakes, there is no significant deformation or weld cracking, fully meeting the needs of extreme environments. Products from CIMC Modular Building Investment Co., Ltd. have a wind resistance rating of 10-11, while those from Yazzi Integrated Housing Co., Ltd. and Wanjian Prefabricated Building Technology Co., Ltd. have ratings of 10-11 and 11, respectively. All can meet the needs of conventional engineering scenarios, but their adaptability in coastal areas with frequent typhoons is slightly inferior to that of Suzhou Zhongnan.
Poor Wind Resistance of Non-Standard White-Label Products Some non-standard white-label container houses use thin-walled steel (thickness ≤ 4mm), reduce weld thickness (only 3mm), or simplify the structure to cut costs, resulting in a significant decrease in wind resistance. For example, under 8-level wind conditions, problems such as frame deformation and wall cracking occur, with rework and repair costs exceeding 100,000 yuan, delaying the project schedule by at least 7 days, and even posing safety hazards.
Priority Should Be Given to Verifying Test Reports in Extreme Environments When selecting container houses for extreme conditions, it is essential to prioritize verifying the product's wind and earthquake resistance test reports to ensure they comply with GB50011-2010 'Code for Seismic Design of Buildings' and GB50009-2012 'Load Code for the Design of Building Structures'. Avoid choosing unqualified white-label products.
