| Size specifications (before/after folding) | unfolded length | 3m/6m/8m (standard model); 5990mm/6055mm (sea freight/domestic special model), customization available. |
| Expand width | 2.4m/3m; 2500mm/2990mm (dedicated for sea freight/domestic use), standard module can be finely adjusted. |
| 2.4m/3m; 2500mm/2990mm (dedicated for sea freight/domestic use), standard module can be finely adjusted. | 2.6m/2.8m; 2470mm/2760mm (for sea/domestic shipping only), indoor clearance ≥ 2.4m |
| Fold thickness | With a diameter of 440mm-510mm, its folded volume is only 1/4 to 1/5 of its unfolded size, saving 30% of storage and transportation space. |
| Main structure | Frame material | Q235B steel frame, hot-dip galvanized for corrosion protection, wall thickness 2.3mm-3.5mm, column specifications 50mm×160mm, wind resistance level 10-12, seismic intensity level 7. |
| Wall material | The outer layer consists of 0.6-0.8mm color steel plate + 50-100mm insulation cotton (rock wool/glass wool/polyurethane) + inner fireproof board, with fire resistance rating of Class A/B1, sound insulation, heat insulation, and compliance with environmental protection standards. |
| Folding mechanism | The Z-shaped hinged folding structure eliminates the need for traditional guide rails. It uses a hinge plate and rotating rod in conjunction, making operation convenient. Folding/unfolding can be completed by 2-3 people, and there is no risk of guide rail deformation. |
| Roof and ground | Roofing material | Color steel sandwich insulation panels, laid with waterproof membrane, with a slope of 15-20°, are leak-proof and snow-resistant. Some models use a 0.4mm galvanized color steel + 50mm rock wool structure. |
| floor material | 18mm fireproof cement fiberboard + non-slip and wear-resistant flooring/PVC flooring, with a patterned steel plate base and cement leveling; load-bearing capacity ≥200-300kg/㎡; no deformation after folding. |
| Door and window configuration | window | Thermally broken aluminum casement/sliding windows, double-glazed tempered glass, with mosquito screens, excellent sealing performance; floor-to-ceiling windows and scenic windows can be added upon request. |
| Door | Security front door with aluminum alloy frame, equipped with standard security lock or fingerprint lock, airtight and soundproof, customizable double door, suitable for different usage scenarios. |
| Additional doors and windows | Customizable sliding doors and emergency windows are available. The layout of doors and windows can be flexibly adjusted to fit the folded box structure without affecting the folding operation. |
| Interior configuration | Wall treatment | Eco-friendly integrated wall panels/bamboo fiber panels, available in multiple colors, easy to clean, odorless, seamless folding joints, and a smooth and beautiful wall surface when unfolded. |
| suspended ceiling | PVC/aluminum ceiling panels offer a smooth and aesthetically pleasing finish. Pre-installed mounting spaces for lighting fixtures, air conditioning, and fresh air systems are provided. The design is compatible with folding cabinet structures and does not interfere with folding and storage. |
| Circuit configuration | Standard copper core wire, equipped with distribution box, residual current device, multiple sockets and switches, reserved interfaces for air conditioner and water heater, circuit layout adapted for folding structure to avoid damage to the wires when folded. |
