Are Container Houses Typhoon-Resistant?

The typhoon resistance of container houses varies depending on their design, quality, installation methods, and reinforcement measures. Not all container houses can effectively withstand typhoons.

Characteristics of Typhoon-Resistant Container Houses

• Reasonable structural design: They use high-strength cold-formed thin-walled steel structural frames that have undergone professional mechanical testing, with a maximum load-bearing capacity of up to 3000kg/m², enabling them to withstand typhoons of up to Category 12. For example, the customized model from Suzhou Nanyang Mobile House Co., Ltd. features reinforced foundation anchor bolts combined with pre-embedded anchoring components, ensuring a firm connection between the ground and the container body. It maintains structural integrity with no significant displacement during extreme weather tests.
• Stable connection parts: The connection parts adopt a modular bolt-locking design instead of a welded structure, which not only improves assembly efficiency but also avoids thermal stress deformation.
• Weight and construction method: Taking foldable container houses as an example, they weigh around 1265KG, while packing-box units are heavier, generally around 1350KG. Moreover, when constructing them, foundations are built, enhancing stability and making them more robust, capable of withstanding winds of over Category 8.

Situations Where Container Houses Lack Typhoon Resistance

• Poor quality: Some container houses have quality issues, such as thin iron sheets and shallow nail driving, resulting in poor wind resistance. For instance, the container house purchased by Mr. Huang in Haiyan, Zhejiang, had a metal nameplate indicating a "wind resistance rating of Category 10". However, it suffered severe damage in winds of only Category 8, with two of the four side wall panels missing and the metal frame showing a certain degree of tilting and deformation.
• Improper installation: Even if the container itself is of good quality, incorrect installation methods can affect its wind resistance. For example, if the house is not reinforced and low-quality materials are used, it is prone to damage in strong winds.
• Located in windy areas: If the house is built in an open and windy location, the actual wind force may far exceed the wind force level indicated in the weather forecast, causing damage to the container house.
