This column focuses on the demand for outdoor space expansion, focusing on modular tunnel tents, which use 210D Oxford cloth and high-strength aluminum alloy frames, and achieve 3-5 meters of longitudinal extension space through multi-arch structures. The product features a detachable partition design as its core highlight: the 5-person model comes standard with 2 independent bedrooms and a central living room, and the 8-person model can be connected to a 10-meter extra-long camp through expansion modules, with PVC waterproof base fabric and ventilation mesh windows, taking into account both rainproof and breathable performance. The differentiated advantages are reflected in: the patented quick-release frame can be set up in 8 minutes, the wind rope fixing system can withstand level 6 strong winds, and the customized LOGO printing is suitable for camping teams or events. From mobile homes for family long-distance camping to temporary rest areas at music festivals and material storage stations for mountaineering teams, flexible module combinations can be used to provide outdoor scenes with solutions that combine spatial flexibility and structural stability.
