The lifespan of prefabricated houses is typically around 5-7 years, influenced by factors such as the usage environment, frequency of use, and maintenance. With optimal conditions and regular maintenance of structural elements, the lifespan can be extended to approximately 10 years.

Materials for prefabricated house steel structures include walkway boards, canopy support rods, tension bars, gable columns, corner columns, gable beams, floor beams, ring beams, floor joists, roof joists, corners, canopy columns, gable one-word beams, gable zigzag beams, center columns, door frames, one-word beams, zigzag beams, triangular brackets, canopy frames, and railings.

Materials for prefabricated house tile bending include canopy panels, PVC windows, floor panels, doors, rock wool panels, rock wool tiles, tile drips, roof ridges, gable closures, waterproof troughs, and wall wraps.

Folding houses have a lifespan of over 10 years, can be reused in different projects up to 5 times, and are highly durable due to their easy folding capability.

Prefab houses have a lifespan of approximately 6 years, experience significant wear and tear during disassembly, and have a very low rate of reuse—around 3 times.

The installation process of prefabricated houses involves several steps, including groove excavation, foundation selection, steel frame installation, color steel plate installation, ground floor construction, door and window installation, and interior decoration. Installing a simple prefabricated house typically takes 3-5 days, with the exact duration influenced by factors such as the house's size, complexity, the skill of installation workers, and weather conditions.

The formula for calculating the area of a single-story standard prefabricated house includes the main area of the house plus the area of the canopy. For a double-story standard prefabricated house, the formula involves adding the main area of the house, canopy area, walkway area, and staircase area. Similarly, for a three-story standard prefabricated house, the formula is comparable to the double-story house, with the staircase area calculated as the number of staircases multiplied by 16.06 square meters.
