20ft Double End Door One Trip Tunnel Container

The 20ft tunnel shipping container is a modified dry freight unit featuring double cargo doors on both ends, enabling through-access for efficient loading and unloading. This one-trip container is in near-new condition, having completed a single voyage from its manufacturing origin .

Key Features

• Double-end door configuration with cargo doors at both ends for through-access and convenient stock rotation 

• One-trip condition with minimal signs of wear from a single voyage 

• Cor-ten steel construction for structural integrity, durability, and corrosion resistance 

• 28mm marine-grade plywood flooring over steel cross-members 

• Factory-fitted lockboxes on each end for enhanced security 

• Two locking bars on each door for secure closure 

• Forklift pockets (2 per side) for ease of handling and positioning 

• Ventilation openings (8 vents) for airflow and moisture reduction 

• CSC certification for intermodal transport compliance with a maximum gross weight of 30 tonnes 

Detailed Description

The 20ft tunnel container is constructed from Cor-ten steel, a weathering steel grade that forms a stable protective oxide layer when exposed to atmospheric conditions, providing long-term resistance to corrosion without requiring frequent repainting .

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 from either side . The dual access points eliminate the need to unload the entire container to access goods stored toward the rear .

As a one-trip unit, this container has completed a single loaded voyage from its manufacturing origin and is offered in near-factory condition . One-trip containers represent the highest quality grade available on the market and are built to last 25-30 years . They may show minor signs of transport, including light scratches and small dents, while maintaining fully intact floors, walls, and door gaskets .

The floor system utilizes 28mm marine-grade plywood panels secured to steel cross-members, providing load-bearing capacity for palletized goods, equipment, and materials . Each door set features steel locking bars and a factory-fitted lockbox for enhanced security . Ventilation openings promote airflow and reduce moisture accumulation .
