40ft High Cube Double Door Tunnel Container

The 40ft high cube double door shipping container, commonly referred to as a tunnel container, is a modified dry freight unit featuring cargo doors on both ends . This configuration enables through-access for loading and unloading operations, making it suitable for logistics, warehousing, and construction applications requiring efficient material flow. The high cube configuration provides additional interior height compared to standard containers .

Key Features

• Cargo doors on both ends providing through-access for efficient loading and unloading without repositioning the container 

• High cube configuration with 9 ft 6 in exterior height, offering approximately 8 ft 10 in of interior clearance 

• Corten steel construction for structural integrity and resistance to corrosion

• Marine-grade plywood flooring (28mm) over steel cross-members

• Steel locking bars on each door set with hasps for secure closure

• Forklift pockets for ease of handling and positioning

• ISO corner castings for lifting and stacking compatibility

• CSC certification for intermodal transport compliance 

Detailed Description

The 40ft tunnel container is constructed from Corten steel, a weathering steel grade that forms a stable protective oxide layer when exposed to atmospheric conditions . This material provides structural integrity and resistance to corrosion, making the container suitable for extended outdoor placement and maritime transport.

The defining feature of this container is its double-door configuration, with a full set of cargo doors at both ends . This design enables access from both ends, facilitating “first-in, first-out” inventory management and allowing loading or unloading operations to be performed from either side without the need to unload the entire container to access goods stored toward the rear . The dual access points also allow for the container to be partitioned internally, creating two separate storage areas if required .

The high cube configuration provides approximately one foot of additional interior height compared to standard 40ft containers, increasing the cubic capacity to approximately 76 cubic meters (2,685 cubic feet) . This extra height accommodates taller items, stacked pallets, and equipment requiring overhead clearance, and supports improved air circulation for stored materials.

The floor system utilizes marine-grade plywood panels secured to steel cross-members, providing load-bearing capacity for palletized goods and equipment . Each door set features steel locking bars compatible with padlocks or security seals. Ventilation openings promote airflow and reduce moisture accumulation .
