Container House Blown Away by Wind

The blowing away of container houses by wind can be caused by various factors, including quality defects, improper installation, and environmental factors.

Quality defects: To reduce costs, some container houses may use thinner iron sheets or non-compliant materials. For example, the container purchased by Mr. Huang in Haiyan, Zhejiang, had thin iron sheets and shallow nail fixings, making it prone to deformation and warping under strong winds, leading to structural damage. Additionally, if fire-resistant and durable filling materials are not used, the overall strength of the house will decrease, making it difficult to withstand strong winds.

Improper installation: The wind resistance of container houses depends on a stable installation method. If the foundation is not reinforced and high-strength galvanized hinges or bolts are not used at the connections, the house is prone to shifting or collapsing under strong winds. For example, Mr. Huang's house was located in an open air vent where the wind force might far exceed Level 8, but the manufacturer did not inform him in advance of the need for additional reinforcement, resulting in the ordinary installation method being unable to withstand the actual wind force.

Environmental factors: The wind force at the location of the house may be exacerbated by the terrain. Wind speeds in open fields, air vents, or beside high-rise buildings may be higher than those forecast by meteorological services. For example, Mr. Huang's house was located in a field with no shelter around, causing the wind force to concentrate and resulting in actual forces far exceeding the stated wind resistance rating of the container.

Misleading advertising: Some manufacturers may exaggerate the wind resistance rating to promote their products. For example, the container purchased by Mr. Huang was labeled as being able to withstand winds of up to Level 10, but the manufacturer admitted that this was just advertising and had not been actually tested. Ordinary container houses, if not reinforced, are unlikely to achieve the stated wind resistance capacity, leading to safety risks for consumers due to misleading information.
