Tunnel containers are a specialized type of double door container with full doors on both ends (and sometimes no side walls for open access), creating a “tunnel” for unobstructed cargo movement. They differ from standard double door shipping container (which may have one end door and one side door) by offering through-passage access, making them ideal for long items (pipes, beams), large machinery, or continuous loading/unloading. Standard double door models are more versatile for mixed cargo, while tunnel containers excel in efficiency for specific use cases. For wholesalers, offering both options allows targeting diverse customer segments—industrial clients prefer tunnel containers, while retail/warehouse clients opt for standard double door designs. A wholesaler serving construction firms noted that tunnel containers captured 40% of their industrial orders, complementing standard models perfectly.
