Product Selection: Configurations & Customization
Select the layout that aligns with your operational requirements. All models share the identical core chassis and mechanical hinge system.
Standard Office Layout: Open-plan workspace with integrated electrical conduits, double-glazed PVC windows, and a security steel entry door.
Accommodation / Living Layout: Pre-partitioned into 2 bedrooms, 1 living area, and 1 independent bathroom module (pre-installed shower, toilet, and vanity sink).
Commercial / Retail Layout: Open floor plan with full-height storefront glass panels, reinforced flooring for heavy foot traffic, and external HVAC mounting brackets.
Application Judgment: Where It Operates Best
Remote Resource Extraction Sites: Serves as immediate site offices, engineer dormitories, and mess halls in mining or oil exploration fields.
Rapid Disaster Recovery: Deployed immediately as triage medical clinics, temporary command centers, or emergency housing units.
Commercial Leasing Fleets: Utilized by rental companies for construction site project management offices or mobile ticketing booths at outdoor events.
Supplier Verification: Manufacturing, Quality & Compliance
Evaluating manufacturing capability before placing a bulk order:
Raw Material Traceability: Steel sheets sourced directly from tier-one mills (Baosteel/Ansteel) with mill test certificates provided per batch.
Welding Standards: All structural welding executed by certified welders holding AWS D1.1 or ISO 9606 qualifications, followed by ultrasonic testing (UT) on critical load-bearing joints.
Surface Treatment Process: Grit blasting to Sa 2.5 standard, followed by a two-coat zinc-rich epoxy primer and an aliphatic polyurethane topcoat (total dry film thickness >= 120 um).
Pre-Assembly Testing: 100% of units undergo trial assembly in the factory, including hinge rotation testing, hydraulic/mechanical lock checks, and water spray testing to prevent joint leakage.
Electrical Compliance: Pre-wired circuits adhere to IEC, UL, or AS/NZS standards, equipped with residual current circuit breakers (RCCB) and industrial commando plug inlets.
Procurement Decision & Logistics Guide
Packaging & Loading: Two folded units can be stacked and loaded into a single 40ft High Cube (40HQ) shipping container or shipped via flat rack carrier. Accessories (interior partitions, plumbing fixtures) are secured inside the central cavity.
Site Preparation: Requires a level concrete slab, compacted gravel bed, or concrete pier footings at designated load-bearing points.
Deployment Labor: Can be unfolded by a crew of 4 workers using a crane or forklift in 45 to 60 minutes. No specialized civil engineering required on-site.
Minimum Order Quantity (MOQ): 1 unit for sample evaluation; 20 units (1 x 40HQ load) for commercial wholesale pricing.
Lead Time: 15–25 working days upon receipt of deposit and technical drawing sign-off.
Frequently Asked Questions
Q: How is water leakage prevented at the folding wing joints?
A: The expansion joints utilize a triple-seal system comprising EPDM compression gaskets, structural silicone sealant troughs, and an overlapping aluminum flashing extrusion. This mechanical barrier prevents moisture ingress during wind-driven rain.
Q: Can the electrical and plumbing systems be certified to local codes (e.g., AS/NZS, NEC, CE)?
A: Yes. We customize the wiring harnesses, breaker panels, socket types (e.g., Type G, Type I, NEMA), and PVC/PEX water supply pipes to match the regulatory standards of your target import destination.
Q: What equipment is needed on-site to unfold the container house?
A: A standard mobile crane or a 5-ton forklift is required to lift and stabilize the hinged wings during deployment. Manual winches integrated into the frame assist with final leveling and locking.
Q: How many units can be stacked vertically?
A: The standard double-wing expandable container house is structurally rated for G+1 (2 stories) stacking. For 2-story configurations, external steel staircases and balcony modules are anchored directly to the corner casting blocks.
Q: What is the warranty policy on structural and non-structural components?
A: We provide a 5-year structural warranty against frame deformation or rust-through failure, and a 1-year warranty on electrical fittings, plumbing fixtures, and sealing gaskets.
