Frequently Asked Questions

Q: How long does it take to expand the 20ft folding house?

With the precision-engineered folding mechanism, the unit can be expanded from its transport size to its full 37㎡ size in a very short time, typically requiring only a small crew and basic tools.

Q: Is the metal structure resistant to corrosion?

Yes, we use high-grade galvanized steel for our metal structures, which provides excellent protection against rust and corrosion, ensuring durability in diverse weather conditions.

Q: Can two units be shipped in one container?

Absolutely. The folding design is specifically optimized for logistics, allowing one 40HQ container to fit 2 pieces, significantly reducing the per-unit shipping cost.

Q: What is the difference between extended size and inside size?

The extended size (L5900W6300H2480mm) refers to the outer dimensions of the house, while the inside size (L5460W6140H2240mm) is the actual usable interior living space.

Q: Is the folding house suitable for permanent residency?

While designed for rapid deployment, the structural integrity and 37㎡ area make it suitable for long-term use as a cabin, office, or residential unit when placed on a proper foundation.

Q: Do you provide other sizes of expandable houses?

Yes, we offer a full range of solutions including 10ft, 20ft, 30ft, and 40ft Expandable Folding Houses to meet different space and budget requirements.
