X-Type Foldable Container House

An X-Type Foldable Container House is a factory-built modular shelter constructed from cold-formed galvanized steel profiles and insulated sandwich panels. Unlike rigid containers or standard flat packs, the X-Type utilizes a dual-pivoting scissor hinge geometry along its longitudinal axes. This kinematic linkage enables the entire roof assembly, side walls, and floor chassis to collapse into a flat slab measuring approximately 42 cm in height. During site setup, lifting the roof pulls the hinged wall panels into position automatically, where they are secured using structural locking pins.

NuPON Gen 2 X-Type units are specifically engineered for tropical and typhoon-prone conditions (such as the Philippines, Pacific Islands, and Southeast Asia). Wind resistance (up to 120 km/h) is achieved by cold-formed Q235B steel corner columns and heavy-duty mechanical locking clamps that prevent structural racking. Water tightness is ensured through continuous vulcanized EPDM elastomeric gaskets along all fold joints, paired with sloped top roof gutters that direct rainwater away from structural seams.

Because an X-Type module folds down to ~420 mm in height, a standard 40ft High Cube (HQ) shipping container can accommodate 10 to 12 fully pre-fitted modules (depending on wall thickness specifications). Compared to standard flat-pack containers (which allow 4 units per 40ft HQ) or fully assembled container houses (which allow only 1 to 2 units per shipment), the X-Type system reduces per-unit landed ocean freight and inland logistics costs by 60% to 70%.

X-Type foldable houses require minimal site preparation compared to traditional concrete construction. A compacted gravel bed, leveled soil with concrete pad footings under the four corner posts, or a basic strip foundation is sufficient. The internal structural chassis compensates for minor surface irregularities, allowing immediate installation without waiting for full slab curing.

NuPON offers three standard core insulation options inside our 50 mm to 75 mm sandwich panels: (1) Rock Wool - Class A Non-Combustible fire rating, ideal for high-risk industrial sites and mining camps; (2) High-Density Polyurethane (PU) - Superior thermal performance ($k$-value $\approx 0.022\text{ W/m}\cdot\text{K}$) for extreme heat or cold; and (3) EPS (Expanded Polystyrene) - Cost-effective thermal insulation for standard site offices.

All electrical wiring (flame-retardant conduits), main circuit breaker boxes, switches, power sockets (compliant with BS, EU, or US standards), and surface-mounted LED ceiling fixtures are pre-installed in the roof and wall assemblies at the factory. Flexible hinge-conduits allow the unit to fold and unfold without pinching electrical cables. Once opened, site personnel simply connect the main external power inlet to the local grid or generator.

NuPON X-Type units have a structural design life of 15 to 20 years under normal environmental maintenance. Thanks to hot-dip galvanization (minimum $120\text{ g/m}^2$ zinc coating) and marine-grade anti-corrosion paint, the structural steel resists oxidation even in humid coastal areas. The heavy-duty mechanical hinges are tested for over 50 complete fold-unfold cycles without structural degradation, enabling multi-project reusability.
