Product overview
The expandable container house is an innovative building solution built on a fully modular, prefabricated design. Taking a standard shipping container as its structural base and integrating folding expandable wings, it unfolds on site to deliver almost three times the internal floor area — while still staying within standard sea-container transport and unloading dimensions. The result is a dramatic gain in space efficiency and on-site layout flexibility.
01Core structure & materials
Main frame
High-strength galvanised square tube and galvanised angle steel build a heavy-duty load-bearing frame with excellent wind and seismic resistance and strong corrosion protection.
Walls & insulation
Double-sided colour-coated steel sandwich panels combine structural strength with fire separation, thermal insulation and heat retention.
Connection & expansion
Industrial-grade high-strength hinges at every key load-bearing and pivot joint keep the structure stable and the seals reliable through repeated folding and unfolding.
02Core advantages
Efficient transport & storage
Folded down it keeps a standard container footprint, cutting sea and road freight costs and simplifying centralised warehousing.
Rapid on-site deployment
With a high level of prefabrication, on-site work is limited to unfolding the two wings, which shortens the construction cycle considerably.
Flexible customisation
Standard 10 ft, 20 ft, 30 ft and 40 ft sizes, plus tailored layouts for housing, temporary offices, commercial showrooms, camp accommodation and other project needs.
