The 40ft Expandable Container House is a large-scale modular solution designed for medium to large space requirements. With a collapsed dimension of 12192×2438×2591mm (standard 40ft container), it can be expanded to an internal area of 48-60㎡, making it suitable for permanent or semi-permanent use. The structure features 2.2mm galvanized steel frames (top/bottom beams and columns) and enhanced insulation with 50mm glass fiber insulation cotton in the roof, ensuring durability and energy efficiency. It integrates multiple functional components, providing a versatile space for offices, residential, or commercial purposes.
Expands from a 40ft container to a double or triple-area space, with a symmetrical expansion design ensuring balanced structure after deployment.
Roof tiles (0.38mm thickness, 2880mm length) and ceiling tiles (0.28mm thickness) are combined with glass fiber insulation cotton, reducing heat transfer and energy consumption.
The frame uses 2.2mm galvanized steel beams (L=5630mm for top/bottom beams) and reinforced columns, supporting multi-functional interior layout (e.g., partitioned rooms).
The expanded space allows for flexible partitioning, with pre-installed interfaces for electrical and plumbing systems to facilitate further customization.

Exhibition halls and pop-up event venues requiring large space
Site Preparation: Ensure the foundation is firm (concrete or steel platform) to bear the expanded structure’s weight (approximately 5-8 tons).
Expansion Operation: Two teams work on both sides to unlock the expansion locks, slowly pull out the side modules, and secure them with ceiling angle aluminum (40×40×0.5mm) and supporting rods.
Structural Reinforcement: Connect the expanded modules to the main frame using m12×25 hexagon socket screws (32 pieces) and apply structural adhesive at joints.
Interior Finishing: Install flooring, electrical wiring, and plumbing according to design, using small white nails (4.2×16mm) for fixing lightweight components.
Q: How many workers are needed for expansion?
A: At least 4-6 workers to ensure safe and smooth expansion of the large modules.
Q: What is the service life of the expandable mechanism?
With proper maintenance, the expansion system can function reliably for 10-15 years.
Q: Can it be equipped with air conditioning and heating systems?
A: Yes, the pre-reserved holes and structural design allow for easy installation of HVAC systems.
