The 20ft Expandable Container House is a space-efficient solution that combines the mobility of standard containers with expandable functionality. Based on a 20ft (6058×2438×2591mm) base structure, it can be expanded horizontally to nearly double its internal area, reaching approximately 24-30㎡ after expansion. The frame uses 2.2mm galvanized steel for durability, while the walls and roof integrate insulation materials to maintain a comfortable internal environment. This product is ideal for scenarios requiring flexible space adjustment, balancing transportation convenience and living/working area.
The side panels can be smoothly extended, transforming from a compact 20ft container into a spacious living/working area without complex tools.
When collapsed, it fits standard container transportation dimensions, reducing logistics costs; expanded, it provides ample space for various uses.
The main structure adopts galvanized steel beams (frame height 160mm) and rock wool sandwich panels (50mm thickness), ensuring stability and thermal insulation.
| Overview (Thickness, size, ingredients can be customized according to customer needs) | 1. The weight of an expansion box is about 2.7 tons. 2. The ground load of the expansion box is 1.5KN. 3. The unfolded area is about 37.288㎡. 4. A 40-foot high container can hold 2 sets. | Picture | |

Transport and Placement: Lift the collapsed container to the installation site using a forklift or crane, ensuring it is placed on a flat, stable foundation.
Expansion Process: Unlock the side locks, pull out the expandable panels, and secure them with the provided support brackets and hexagon screws (60×100mm).
Sealing and Fixing: Use structural adhesive to seal the gaps between expanded panels and the main frame, preventing water leakage.
Interior Assembly: Install internal fixtures such as flooring, windows, and doors according to the instruction manual, using self-tapping screws (100mm) for fixation.
Q: What is the maximum wind resistance of the expanded house?
A: It can withstand wind speeds up to 100km/h when properly installed with all supports fixed.
Q: How to maintain the expandable mechanism?
A: Regularly clean and lubricate the sliding rails to ensure smooth expansion; check for rust and apply anti-corrosion paint if needed.
Q: Is it possible to stack multiple units?
A: Stacking is not recommended for expanded units, but collapsed 20ft containers can be stacked up to 3 layers under proper support.
