Disadvantages of Container Mobile Houses
The disadvantages of container mobile houses are mainly reflected in fire safety hazards, limitations in materials and structure, restrictions on usage environments, and risks in quality supervision.
Prominent fire safety hazards: Container mobile houses mostly use steel structures and materials like polystyrene. Although some materials have flame-retardant properties, the overall fire safety performance still has defects. For example, electrical circuit failures can easily ignite surrounding combustibles, leading to rapid fire spread. Fire accidents in container houses have occurred in Linping District, Hangzhou, Anci District, Langfang, and Binhai New Area, Tianjin, resulting in property losses and even casualties. In high-temperature environments, the strength of steel significantly decreases, and it is prone to deformation or even collapse at around 600℃, further exacerbating the fire risk.
Limitations in materials and structure: Some container houses use inferior steel or cut corners to reduce costs, resulting in insufficient structural stability. For example, if the steel structure of a foldable container house deforms or bends, it needs to be replaced promptly; otherwise, it may cause safety accidents. When exposed to humid environments for a long time, steel is prone to rust, affecting the durability of the house. In addition, second-hand container houses, due to their long service life, may have aged welds and anti-corrosion coatings, requiring comprehensive inspection before use.
Obvious restrictions on usage environments: Although container houses are movable, their sealing processes, which can prevent leakage and moisture, may still be damaged under extreme weather conditions (such as strong winds and heavy rain). In high-temperature areas, additional fire-proof cladding is required, and in humid areas, enhanced anti-corrosion treatment is necessary; otherwise, structural failure may occur. At the same time, although their modular design facilitates combination, the compact spatial layout may limit living comfort.
Risks in quality supervision: The production of container houses involves multiple links such as raw material procurement, design demonstration, and component sampling inspection. If quality supervision is not in place, potential safety hazards may arise. Some manufacturers, in pursuit of profits, use inferior materials, resulting in houses that do not meet wind and earthquake resistance standards. In addition, personalized renovation needs (such as water and electricity integration and interior decoration) rely on professional teams. Improper renovation may affect living safety.
