The double-door openings at both ends of the container make the loading, unloading and sorting of goods easier and more flexible. Moreover, by keeping one of the doors closed for a long time, it can also be used as a regular dry container. Double-door containers can be used for transporting various types of ordinary dry goods, bulk goods and special goods. Specifically, they can easily transport motorcycles, cars and snowmobiles. In addition to transporting goods, on construction sites, double-door containers can be built into temporary passages, fully leveraging their advantages of safety, durability and ease of installation.
