Closed Van

In shipping, a closed van refers to a type of container or trailer used to transport cargo that requires protection from the elements or from theft. A closed van is a fully enclosed container with a roof, walls, and a floor, and is designed to provide maximum protection for the cargo being transported. 

Closed vans are typically made of metal, such as steel or aluminum, and can range in size from small vans to large trailers. They are commonly used to transport goods that are susceptible to damage from exposure to the weather or that require extra security, such as electronics, clothing, or high-value items.
