A new 20ft double door container has full-size cargo doors at both ends instead of just one. Open both ends and you have a tunnel straight through the container, which makes loading, unloading and reaching stock at either end far easier. Prime Cargo Box sells this unit new, wind and watertight and CSC plated, ready for storage, shipping or conversion.
Double door containers are also called tunnel containers or double-ended containers. Here is how they differ from a standard 20ft, the full specification and what buyers use them for.
Why Choose a New 20ft Double Door Container?
In a standard container, the goods you put in first end up trapped at the closed end. With a new 20ft double door container, nothing is ever more than half a container away from a door. You can keep fast-moving stock at one end and slow-moving stock at the other, load from one end and unload from the other, or drive a pallet truck straight through.
The second set of doors also improves airflow when both ends are open, which helps on hot days or when you’re working inside. And because it is new, the paint, seals and both sets of door hardware start their life with you.

Is a New 20ft Double Door Container Worth the Extra?
For a lot of buyers, yes. The price difference over a standard new 20ft is usually small, and the benefit shows up every time you use the container. Anyone who has stored goods in a standard box knows the routine of pulling half the contents out to reach one item at the back. A new 20ft double door container ends that, because the back is simply the other front.
It is less useful if the container will sit with one end hard against a wall or fence with no room to open those doors. In that case a standard 20ft gives you a few centimetres more space for less money. If both ends can be reached, the double door is almost always the better buy.
Popular Uses
Buyers choose a new 20ft double door container for jobs like these:
- Stock storage where items go in one end and out the other
- Builders’ stores with tools at one end and materials at the other
- Garden and farm storage with access from two directions
- Walk-through workshops, studios and pop-up shops
- Linking two areas of a site, such as a yard and a car park
- Shipping goods that need unloading from either end
Our container modification team can add lighting, shelving, vents and personnel doors before delivery.
How the New 20ft Double Door Container Is Built
The shell is Corten steel, used across the industry because it resists corrosion far better than mild steel. Both ends have full door frames, each with two doors, four locking bars and rubber gaskets, so the container is wind and watertight whichever end you use. The floor is marine plywood on steel cross members, rated for forklift and pallet truck traffic. Many 20ft units also have forklift pockets in the base for moving the container when empty.
The outside dimensions follow ISO 668, so the container fits standard trailers and lifting gear, and it carries a CSC plate for shipping.
Planning Your Layout
Think about how stock will move. A common setup is shelving down both walls with a clear aisle between the two door sets, so you can walk or roll a pallet truck straight through. If you use one end for loading and the other for picking, put the heaviest or bulkiest goods near the loading doors. In a workshop, a bench at one end and storage at the other keeps tools and materials apart.
Site Requirements for a New 20ft Double Door Container
Leave room in front of both ends so all four doors can open fully, roughly 2.5 m at each end. Prepare a firm, level base about 6.5 m by 2.5 m using concrete, compacted gravel or blocks under the corners. Keeping it level matters more on a double door container, because there are two door sets that need to stay square. Our shipping and delivery policy explains how delivery is quoted.

Looking After a New 20ft Double Door Container
New containers need very little upkeep, but with two door sets it pays to treat both equally. Grease the hinges and locking bar cams at each end once or twice a year, even on the end you use less, so they don’t seize. Keep the roof clear of leaves and standing water, and keep soil away from the bottom rails. Add vents or moisture absorbers if you store anything sensitive to damp, since condensation can form inside any sealed steel container overnight.
Using It for Export
Because it carries a valid CSC plate, a new 20ft double door container can be loaded and shipped like any standard box. Being able to load from one end and unload from the other is useful when cargo has to come off in a particular order at the destination. Give your freight forwarder the container number and tare weight from the door markings when you book.
Security
Two door sets mean two places to lock. Each end has padlock lugs on its locking bars, and we can fit a welded lockbox at each end before delivery. Where possible, place one end against a wall or fence and use it only when you need to, which halves the exposed doors.

Frequently Asked Questions
What is the difference between a double door and a tunnel container?
Nothing. Both names describe a container with cargo doors at each end. You may also see it called a double-ended or dual-door container. Whatever the name, the key point is a full set of cargo doors, with locking bars and gaskets, at both ends of the box.
Does a new 20ft double door container hold less than a standard 20ft?
Very slightly. The second door frame takes about 6 cm off the internal length, which works out to around 0.4 m³ less volume. In practice the easier access more than makes up for it.
Can I ship goods in a new 20ft double door container?
Yes. It carries a CSC plate and is accepted for shipping.
Is it as watertight as a standard container?
Yes. Both door sets have full gaskets and seal the same way, provided the container sits level so the frames stay square.
Do you deliver worldwide?
Yes. Contact Prime Cargo Box for a delivered price on a new 20ft double door container.
