Select optionsTunnel containers, also known as double door containers, feature full-height cargo doors at both ends. This dual-entry design gives faster access to stored goods and opens up flexible uses that standard single-door containers cannot match.
With full-height double doors at each end, you can load from either side and reach any item without having to move through the entire length of the container. This dramatically reduces the time it takes to find and retrieve stored goods.
When both sets of doors are opened on each end, you create a clear drive-through path. Forklifts and pallet trucks can enter from one end and exit the other, speeding up loading and unloading on busy sites.
Each set of doors comes with heavy-duty locking gear and a factory-fitted lock box. Both ends of the container are fully secure, giving you the same level of protection you would expect from any shipping container.
Available in standard 20ft and 40ft sizes, our tunnel container range also includes 30ft cut-down units and high cube versions with an extra foot of headroom, so you can always find the right fit for your needs.

A tunnel container is a shipping container with full-height cargo doors at both ends instead of just one. This dual-entry design is why they are also called double door containers. The doors at each end open and lock independently, giving you flexible access from either side of the unit.
We stock tunnel containers in 20ft and 40ft lengths as standard, with high cube versions available for additional headroom. Our in-house team can also cut down containers to create bespoke sizes such as 30ft units.
Tunnel containers serve a wide range of purposes. Common uses include storage where you want to organise goods by section and access each end independently, drive-through loading on busy sites where forklifts need to enter one end and exit the other, event infrastructure such as covered walkways or secure entry tunnels at concerts, festivals, and sporting events, and partitioned spaces where an internal wall divides the container into two separate rooms accessed from opposite ends.
Yes. We can fit an internal partition wall to divide the container into two separate, independently accessible spaces. This is a popular option for sites that need a workshop on one side and storage on the other, or separate storage areas for different teams or product types.
Yes, we stock high cube tunnel containers in both 20ft and 40ft lengths. The high cube version adds an extra foot of internal height (9ft 6in external), which is useful for storing taller items or for conversions where insulation and ceiling installations reduce headroom.
All our tunnel containers are built from heavy-duty corten steel with secure doors and factory-fitted lock boxes at both ends. Each set of doors locks independently, giving you full control over access from either side of the container.
