What Is a Double Wing Folding Room?

A Double Wing Folding Room is a prefabricated steel-framed structure whose two lateral "wings" hinge outward from a central core module. In the folded (transport) state the unit occupies the footprint of a standard ISO shipping container; once the wings are deployed, the usable floor area triples. The entire expansion can be completed by a small crew without heavy machinery, making rapid on-site setup possible in virtually any location.

The design draws on light-gauge steel framing combined with environmentally friendly colour-steel EPS (Expanded Polystyrene) sandwich panels for walls, roof, and floor. Because cabinets, wiring, plumbing, and finish elements are pre-installed at the factory, the overall project completion rate exceeds 95% before the unit leaves the production line.

Technical Specifications & Dimensions

Cymdin produces Double Wing Folding Rooms in 20-foot and 30-foot configurations. The table below summarises the published dimensional data for the standard 20-foot wing folding house.

The 30-foot variants extend the footprint further and are available in several interior configurations including two-bedroom layouts and dedicated office-plus-meeting configurations. Both size families support stacking for multi-storey deployments when fitted with appropriate structural column upgrades.

Materials & Structural Engineering

Light-Gauge Steel Frame

The primary load-bearing skeleton is fabricated from hot-dip galvanised light-gauge steel sections. This choice delivers a high strength-to-weight ratio critical for transportability while resisting corrosion over a service life measured in decades. The hinge mechanisms that enable wing deployment are engineered to maintain structural rigidity after repeated fold-unfold cycles.

EPS Colour-Steel Sandwich Panels

Wall, roof, and floor panels consist of two galvanised steel facings bonded to an EPS core. EPS provides thermal insulation values (typically λ ≈ 0.033–0.040 W/m·K), sound damping, and fire-retardant performance. The panels are lightweight, recyclable, and carry no harmful off-gassing — a key factor in Cymdin's commitment to environmentally responsible construction.

Surface Treatments

Exterior steel surfaces are available with UV-resistant anti-sun spray coating, metal brushed finish, or wood-grain cladding film — providing both weather protection and aesthetic differentiation without the mass of traditional cladding materials.

Interior Layout & Functional Configuration

Despite shipping in the footprint of a single container module, the deployed Double Wing Folding Room accommodates a surprisingly complete domestic or commercial programme. Cymdin's standard interior partition system supports the following spatial arrangements:

The layout can be reconfigured for one-bedroom or two-bedroom plans. Dry and wet zones are segregated as standard, an important sanitation feature for both residential and commercial deployment.

Customisation Options

Cymdin offers a six-axis customisation framework for the Double Wing Folding Room, covering everything from structural layout through intelligent systems integration.

1. Structural Layout

Single-room, multi-room, and multi-storey layouts are all achievable. Door types — swing, sliding, or motorised — and window sizing can be specified independently to optimise ventilation, daylighting, and privacy. Multiple units can be connected edge-to-edge to create compound structures for larger commercial or residential programmes.

2. Appearance & Brand Customisation

Exterior wall colour, pattern, and coating material can be matched to a company's brand guidelines. Company logos, illuminated signage, and LED atmosphere strips are available for commercial deployments such as pop-up retail, exhibition stands, or hospitality venues.

3. Smart & Energy-Saving Systems

Optional IoT integration allows remote monitoring of temperature, humidity, and security status. Smart door locks, automated curtain systems, environmental-sensing lighting, solar panels, and energy-storage batteries can all be factory-fitted, turning the folding room into a largely off-grid, connected unit.

4. Climate Adaptability

Panel thickness, thermal-break detailing, fresh-air ventilation systems, and reinforced snow-load frames can be specified to suit local climate conditions from tropical coastal to sub-arctic continental environments. Foundation options include anchor bolt fixing, structural steel base frames, and mobile wheel sets for temporary deployments.

Application Fields

Logistics, Delivery & Lead Times

One of the principal engineering advantages of the Double Wing Folding Room is that its transport dimension of L5,900 × W2,200 × H2,480 mm fits within standard 40-foot high-cube container profiles. A single folding room model typically ships in two 40HQ containers, enabling straightforward multimodal freight by sea, road, or rail.

For buyers with no prior import experience, Cymdin offers DDP (Delivered Duty Paid) service, handling customs clearance, inland freight, and final-mile delivery as a single managed process.
