Demountable Portable Container House

Product Overview & Technical Specification
The demountable portable container house uses a cold-formed, hot-dip galvanized steel primary frame bolted together on-site, paired with modular sandwich wall and roof panels. Engineered strictly for flat-pack logistics, up to 4 to 6 standard units stack and pack inside a single 40-foot High Cube (40'HQ) ocean freight container.
Core Technical Parameters

To evaluate how our modular units withstand extreme environments, review the key structural nodes engineered into every flat-pack assembly:
Corner Casting Nodes (ISO 1161): Cast steel corner blocks welded to the primary columns, handling multi-story stacking loads and crane hoisting points.
Concealed Drainage Columns: Four hollow corner posts featuring internal PVC downpipes that channel roof rainwater directly to the ground, eliminating exterior wall staining and window leakage.
Thermal-Break Wall Junctions: Tongue-and-groove sandwich panel joints sealed with EPDM rubber gaskets to eliminate thermal bridging and air infiltration.

Different geographic regions demand specific structural calculations and electrical/fire certifications. Select your target market specification:
North American Market (USA & Canada):
Standards: Engineered in accordance with IBC (International Building Code) and ASCE 7 wind/snow load requirements.
Electrical: UL/CSA certified distribution panels, receptacles, and wiring harnesses available upon request.
Australian & New Zealand Market:
Standards: Designed to meet AS/NZS 1170 (Structural design actions) and NCC (National Construction Code) provisions.
Materials: BAL (Bushfire Attack Level) rated panel options available for high-risk zones.
European & International Market:
Standards: CE / EN 1090 structural steel fabrication compliance and ISO 9001 factory production control.

Selecting the correct specification depends on your site's environmental exposure, occupancy duration, and local building codes.
Standard Site Office Configuration:
Application: Short to medium-term construction site offices (1 to 3 years).
Specification: 50 mm EPS sandwich panels, standard PVC flooring, single-glazed aluminum windows, standard electrical distribution box.
Extreme Climate / Workforce Camp Configuration:
Application: Long-term mining camps in high-heat, sub-zero, or high-humidity zones.
Specification: 75 mm or 100 mm Rockwool panels (A1 fireproof), double-glazed argon-filled PVC windows, heavy-duty insulated steel exterior doors, heavy-duty vinyl flooring, integrated concealed electrical wiring conduits.
Multi-Story Combination Configuration:
Application: Multi-story modular complexes (up to 3 stories stacked).
Specification: Reinforced corner casting nodes, secondary structural bracing columns, heavy-duty floor load distribution beams, external staircase modules.

Mining & Resource Camps: Rapidly deployable workforce accommodation, mess halls, and administrative offices in remote extraction sites.
Infrastructure & Civil Engineering Sites: On-site contractor offices, tool storage depots, and security guardhouses.
Disaster Relief & Humanitarian Aid: Prefabricated emergency clinics, temporary triage units, and modular classrooms deployed immediately following natural disasters.
Commercial & Industrial Facilities: Temporary site sales offices, remote gatehouses, and modular workshops.

Evaluating a manufacturing partner requires verifying factory infrastructure, quality control processes, and material tracking.
Manufacturing Infrastructure:
Automated profiled steel roll-forming lines ensuring precise dimensional tolerance (+/- 1 mm).
In-house robotic welding stations for primary corner blocks and structural node fabrication.
Continuous polyurethane and rockwool sandwich panel lamination lines.
Surface Treatment & Corrosion Control:
Acid pickling and phosphating tanks prior to hot-dip galvanizing to ensure complete rust removal.
Electrostatic powder coating booth operating at 200 deg C curing temperature for uniform paint adhesion.
Quality Assurance & Testing:
Raw material thickness testing via ultrasonic gauges prior to production.
Pre-assembly trial of structural frames in the factory yard to verify bolt-hole alignment accuracy.
Water penetration testing on assembled prototype units.
Certifications:
ISO 9001 Quality Management System.
ISO 14001 Environmental Management System.
CE Certification / EN 1090 structural steel fabrication compliance.

Optimizing total landed cost requires analyzing container packing density and on-site labor requirements.
Flat-Pack Logistics Calculations:
Standard configuration allows 4 to 6 units packed into one 40'HQ container, reducing ocean freight costs by up to 70% compared to pre-assembled volumetric modular units.
On-Site Assembly Metrics:
A standard 20ft unit (6058 x 2438 mm) can be assembled by a crew of 4 unskilled workers using 1 small crane or fork-lift in approximately 4 hours, relying strictly on bolted connections without on-site welding.
Warranty & Spares:
10-year structural frame warranty against manufacturing defects.
Supplied with a standard package of extra fasteners, touch-up paint, and replacement rubber gaskets.
