Is this the best built new shipping container? You be the judge...
You want a shipping container to be secure and durable, especially if safeguarding the property stored inside is important to you.
Our new 20ft shipping containers stand out from inferior containers in two clear ways:
First, each unit is manufactured to a higher standard to help fight off corrosion and go the distance.
We do this by using thicker corten steel and the right amount of protective marine grade paint. This helps defend your container from developing rust leaks – keeping your things dry inside far into the future.
And that’s not all.
You get extra built-in features giving even more self-storage use advantages. These features help you with condensation risk reduction, lock security protection, plus much more.
These containers are not just built to ISO standards, they exceed them.

3 things we do to make your delivery as smooth as possible
Getting a stress free delivery is probably near the top of your list when it comes to buying a container.
That’s why we have a step-by-step process to take care of that.
Once you’ve purchased your container we will arrange a date for delivery that’s convenient for you. Delivery is usually possible within 3-5 working days and sometimes sooner.
We’ll also send you a delivery questionnaire which helps us get to know your site and be advised of any access restrictions we need to know of.
On the day we also ask the delivery driver to call you en-route so you’re kept well informed.
As you’ll discover, our drivers are friendly and have a “can do” approach to help position your container where you ideally need it.
Frequently asked questions
How long does delivery take?
Delivery is typically within 3-5 working days, sometimes sooner. We’ll agree a convenient date with you.
Can I see the container before I buy?
Absolutely. Our wind and watertight warranty means most buyers save themselves the time but the option is there if you want to visit.
What is a CSC plate?
It’s a steel plate located on one of the doors and displays information about your container. The CSC plate is important if you plan to ship your container overseas as it confirms the container is in seaworthy condition. New containers have a 5-year plate validity from date of manufacture. If you are buying a used container for shipping use let us know in advance so we can have it certified.
How heavy is a 20ft container?
The tare weight depends on the manufacturer. Some are built with thinner steel which is not optimal for corrosion protection amongst other things. Adaptainer specification new containers are built to the recommended minimum tare weight of 2,185kg. This means it’s a full specification ISO container, not a low specification unit.
How does your guarantee work?
We give you an extended wind and watertight warranty of 5-years for new ‘one trip’ containers and 12-months for used. This means should there be any issues with the watertightness of your container during these respective guarantee periods we will send an engineer to carry out a repair or replace your container free of charge should it be required.
How old are your used 20ft containers?
Shipping lines usually retire containers after around 12-14 years. The age of the container is not as important as the structural condition however since some containers could have had more rigorous use than others. All our containers are guaranteed as being structurally sound under our wind and watertight guarantee periods.
Where can I buy a 20ft container?
Right here. We stock containers at 12 depots throughout the UK including, Essex, London, Felixstowe, Birmingham, Manchester, Liverpool, Leeds and Coatbridge. You can purchase by requesting a quote online or calling us.
How much is a 20ft container?
The cost will vary on whether you want a new or used container and your delivery post code (containers located in certain depots cost less due to proximity to ports). Check this page for starting prices or request a online quote now.
What is a one trip shipping container?
One trip shipping containers are newly built shipping that have been shipped once from the factory for repositioning purposes to the UK.
Can I rent?
Yes, we rent them too. See the hire page for more details or request a quote.
Should I put anything underneath the containers?
You may wish to put railway sleepers (one at each end) or concrete blocks (one on each corner) underneath your container. This is especially useful if you’re going to position your container on grass for example as it can help protect the underside from accelerated corrosion and help keep the container level (level ground is important for the doors to operate correctly)
What is a "one trip" or "once used" ISO container?
This is a new container that has been shipped once from the factory for positioning purposes.
