A new 40ft double door container is a factory-new 40ft box with full cargo doors at both ends. It gives you 12 metres of storage you can reach from either end, with unmarked paint, straight panels and fresh seals on both door sets. Prime Cargo Box sells it new, wind and watertight and CSC plated, for buyers who want the best-condition tunnel container available.
New is the right grade when the container will be on show, converted into a working space or kept for many years. Below is the specification, how it compares with a standard 40ft, and what to plan for before delivery.
Why Buy a New 40ft Double Door Container?
Two reasons usually decide it. The first is access: with doors at both ends, nothing in the container is more than about six metres from a door, so you never have to empty one end to reach the other. The second is condition: a new 40ft double door container has never carried cargo, so there are no handling marks, no old logos and no wear on either set of door hardware.
That makes it the natural choice for projects people will see, such as retail units, cafes, site offices and exhibition spaces, and for long-term storage where you want the container to last as long as possible with minimal maintenance.

How the New 40ft Double Door Container Is Built
The shell is Corten steel, chosen for shipping containers because it resists corrosion far better than mild steel. Each end has a full door frame with two doors, four locking bars and rubber gaskets, so the container is wind and watertight from either side. The floor is marine plywood on steel cross members, rated for forklift and pallet truck traffic. The outside dimensions follow ISO 668, and the container carries a CSC plate under the International Convention for Safe Containers, so it can be shipped with cargo as well as used for storage.
Projects That Suit a New Tunnel Container
A new 40ft double door container is a strong base for conversions because both ends can become entrances. Common builds include:
- Cafes and bars with a serving end and a stock end
- Retail and pop-up units with customers entering at one end and leaving at the other
- Site offices with a meeting room at one end and storage at the other
- Workshops where vehicles or machinery can pass straight through
- Covered walkways linking two parts of a site
Our container modification team can add insulation, windows, personnel doors, power and lighting before delivery.
Is New Worth It Over One Trip?
For pure storage, a one trip unit is usually the better value: it performs the same and costs less. A new 40ft double door container earns its premium when appearance matters or when you will invest heavily in a conversion. Retail, hospitality and office builds sit in front of customers and staff every day, and starting with unmarked steel saves on paint prep and gives a cleaner finish. New is also the safer choice if you want the longest possible service life with the least maintenance.
Another advantage is certainty. With a new 40ft double door container you know its full history, because it starts with you.
Planning a Conversion
Plan openings early. In a new 40ft double door container, the two end door frames already give you two full-width entrances, so many projects only need windows and perhaps one personnel door on the side. Keep cuts away from the corner posts, have the frame reinforced around each opening, and decide where power enters before the walls are lined. Insulation of 50 to 75 mm still leaves a usable ceiling height of around 2.2 m in a standard-height box; if you need more headroom, ask us about high cube options.
Using It for Export
Because it is new and plated, a new 40ft double door container can be loaded and shipped straight away. Loading from one end and unloading from the other is useful when goods must come off in a set order at the destination.
Storage Layout
For storage, run racking along both walls with a clear aisle from end to end. Use one end for incoming stock and the other for picking, so older stock always leaves first. If two departments or businesses share the container, give each an end and fit a mesh partition in the middle. Keep heavy items low and spread along the floor.
Site and Delivery for a New 40ft Double Door Container
A 40ft container needs a long, straight truck approach and firm ground. On site you need a level base of about 12.5 m by 2.5 m and roughly 2.5 m clear at each end for the doors. Over 12 m, the base has to be level along its whole length, otherwise one set of doors will bind. A concrete pad, or compacted gravel with solid supports under the corners and at mid-length, works well. The container has no forklift pockets and is lifted by its corner castings. Our shipping and delivery policy explains how we quote delivery.
New, One Trip or Used?
This listing is the new 40ft double door container. If you want near-new condition for less, the one trip 40ft double door container has made one voyage. For basic storage on a budget, see the used 40ft double door container. For full side access, look at the 40ft open side container.
All tunnel units are in our double door containers category.
Care and Security
A new container needs little upkeep. Grease the hinges and locking cams at both ends once or twice a year, keep the roof clear of standing water and keep soil away from the bottom rails. Each end has padlock lugs, and we can weld a lockbox at each end before delivery. If one end will rarely be used, facing it toward a wall or fence adds security.

Frequently Asked Questions
What is the difference between a new 40ft double door container and a tunnel container?
None. Both names describe a container with cargo doors at each end. You may also see it called double-ended or dual-door. What matters is that each end has a full door set with locking bars and gaskets.
Does a new 40ft double door container hold less than a standard 40ft?
Very slightly, because of the second door frame. The difference is well under 1 m³, which is far outweighed by being able to reach both ends without moving anything.
Can I ship goods in a new 40ft double door container?
Yes. It carries a CSC plate and is accepted for shipping by carriers worldwide.
Are both ends watertight?
Yes. Both door sets have full gaskets. Keep the container level so both frames stay square, and check the base again after heavy rain or ground works nearby.
Do you deliver worldwide?
Yes. Contact Prime Cargo Box for a delivered price on a new 40ft double door container.
