Igloo tents from Tianjin Dacheng International Trading Co., Ltd. are constructed using a combination of high-quality materials chosen for durability, weather resistance, and functionality. The tent fabric is commonly made of polyester or nylon, both of which are known for their strength and water resistance; these materials are often coated with a polyurethane (PU) layer to enhance waterproofing, with a hydrostatic head rating indicating their ability to withstand water pressure. For eco-friendly models, recycled polyester or biodegradable fabrics may be used. The tent frames are typically made of aluminum or steel, providing the necessary strength and flexibility to maintain the dome shape while resisting corrosion and wear. Seams are sealed with waterproof tape to prevent leaks, and zippers are often heavy-duty and corrosion-resistant, especially for tents designed for coastal or wet environments. Mesh panels used for ventilation are made of fine, durable mesh to keep insects out while allowing airflow. Additionally, some tents may include insulated layers, such as thermal blankets or foam panels, for cold-weather use, and specialized coatings to resist UV rays or fire in certain models.
