The life span of a mobile house varies greatly, mainly affected by the following factors:
1. Material quality
Steel structure: For example, a mobile sun room usually has a life span of 5-10 years, because the steel welding parts are prone to rust and the waterproof layer ages quickly.
Aluminum alloy: The life span of a mobile sun room with an aviation-grade aluminum alloy frame can reach more than 30 years, with strong corrosion resistance and special surface treatment.
Plastic/Fiberglass: Commonly used in mobile toilets, high-quality materials have a life span of more than 7 years, which can be extended to 20-30 years with proper maintenance.
2. Use environment
Harsh outdoor environments (high temperatures, heavy rains, strong winds, etc.) will accelerate material aging and shorten their life span. For example, ordinary mobile houses can only be used for 4-5 years without maintenance on the construction site, while they can be extended to 10-20 years if the environment is good and maintenance is in place.
3. Maintenance
Regular cleaning and inspection (such as repainting and replacing waterproof layers) can significantly extend the life span. For example, a mobile toilet can last for more than 30 years through maintenance, and the lifespan of a prefabricated house can be doubled after maintaining the beams and columns.
