Portable Standard Container House

The Portable Standard Container House is a bolted, demountable modular steel structure engineered for rapid deployment as site offices, workforce accommodation, and industrial auxiliary spaces. Built around a standardized 20ft footprint (6058mm x 2438mm x 2896mm), units can be linked horizontally or stacked up to 3 stories to configure custom spatial layouts.

Procurement teams must specify configuration tiers based on project site conditions and operational life-span requirements:
Standard Site Utility (Short-to-Medium Term)

• Frame: Standard Q235B galvanized steel with epoxy zinc-rich primer.
• Insulation: 50mm EPS (Expanded Polystyrene) or Glass Wool panels.
• Application: Domestic construction site offices and dry-storage shelters in moderate climates.

Heavy-Duty Industrial & Remote Camp (Long-Term / Severe Climate)

• Frame: Upgraded Q355B structural steel, fully robotic-welded, hot-dip galvanized (zinc layer >= 80 um).
• Insulation: 75mm or 100mm Rock Wool panels (high density) or PIR panels for thermal efficiency.
• Application: Mining camps, coastal infrastructure sites, and high wind/snow load regions.

Construction & EPC Project Camps: Rapid assembly of modular multi-room dormitories, executive site offices, and mess halls.
Industrial Equipment Shelters: Enclosures for electrical switchgear, backup generators, and battery energy storage systems (BESS).
Emergency & Relief Infrastructure: Rapid deployment temporary clinics, quarantine units, and administrative command posts.

Structural Integrity & Corrosion Protection

• Steel Framework: Primary load-bearing columns and beams utilize cold-formed structural steel profiles. All welding complies with AWS D1.1 structural welding standards.
• Surface Treatment: Degreasing, phosphating, and electrostatic polyester powder coating (thickness >= 60 um) applied after shot-blasting. For coastal environments, hot-dip galvanizing is applied post-fabrication.

Envelope & Insulation Performance

• Sandwich Panels: Tongue-and-groove joint design with concealed fasteners eliminates thermal bridging and prevents moisture ingress.
• Sealing System: EPDM rubber gaskets fitted across all door, window, and roof perimeter joints to achieve waterproof rating up to 300 Pa water penetration resistance.

Factory Pre-fabrication & Testing

• Pre-wired Electrical: Distribution box, concealed PVC conduits, MCBs, LED lighting fixtures, and comms sockets pre-installed to regional building standards (CE / UL certified components).
• Pre-assembly Audit: 100% of frame components undergo dimensional accuracy checks on precision jigs prior to surface treatment. Full trial assembly performed for custom structural batches.

To minimize international ocean freight costs, units are supplied in a Flat-Pack configuration.
Shipping Density: 4 standard units (without toilets/extras) or 2 standard units (fully equipped with sanitary modules) pack flat into a single 40ft High Cube (40HQ) container.
Assembly Efficiency: A 4-person crew with a forklift or crane can erect one standard unit in 4 man-hours using standard hand tools (no field welding required).

In-House Manufacturing Assets: 45,000 m^2 production facility equipped with CNC laser cutting machines, robotic welding workstations, and automated continuous polyurethane/rock wool sandwich panel production lines.
Traceability: Raw steel sourced exclusively from top-tier mills (Baosteel/Ansteel) with mill test certificates (MTC) provided per shipment.
Export Compliance: Full structural calculation reports provided stamped by certified professional engineers (PE) upon request to match target regional codes (IBC/ASCE, AS/NZS, or EN Eurocodes).

Technical Inquiry Submission: Provide site meteorological data (wind speed, snow load, seismic zone) and layout requirements.
Engineering Proposal: Receive 2D/3D shop drawings, bill of materials (BOM), and structural calculations within 48 hours.
Sample / Pilot Order: Flexible MOQs starting from 1 unit for evaluation, or 4 units to fill a single 40HQ trial shipment.
Production & Inspection: Third-party inspection (SGS, BV, TUV) welcomed prior to final balance payment.
