20ft long x 8ft wide x 8ft 6" high - 20ft containers are one of the 2 industry standard sizes, because of this, they are often the most cost-effective option when looking for a used container. Used 20ft's are amongst the cheapest shipping containers you can buy. We always have extensive stocks, all available for delivery throughout the UK (or you can collect from our depots if you prefer). Second-hand 20ft's are our most popular product as they offer superb cost per square ft storage and are great for conversion projects.

20 ft Container Construction

Used 20ft units are manufactured using high-quality cor-ten steel, which is designed to stand up to the harsh rigours of sea conditions. We would expect a properly maintained used container to last you in excess of 15 years from the date of purchase from us. Our second-hand shipping containers are typically 10 – 15 years old from date of manufacture, the double doors will be fully operational and the door seals fully intact to prevent any water ingress. Flooring is formed from 27mm hardwood.

Each container is usually picked from the depot on a 'next from stack' basis, so the external paint colour of each unit will vary.

If you require your used container for shipping overseas, we can update the details on the CSC plate. Please advise us if this is a requirement when ordering.

Container Security

To improve the security of your unit we can provide your container with a lock-box (a steel box welded on the double doors to enclose a padlock thus making is less tamper proof) and a high-security padlock. We can also paint the unit and provide many other extras.

Your Container Delivery

Unless otherwise specified, we will deliver your box on a HIAB assisted vehicle so that we can lift the unit to ground where you need it - if you are able to offload your container when we deliver it to your location please let our sales team know - this may reduce the delivery cost if we can deliver using a different type of vehicle. Please be sure to provide us with your exact delivery postcode on the enquiry form below, also please let us know if there are any access restrictions at or near your delivery location which could affect the successful delivery of your container. For more info on our delivery process click here.

Important Questions you should ask about Used 20-ft Shipping Containers

What are the dimensions of 20-ft shipping container?

All shipping containers are a created at a 'standard' size (in order to stack them during shipping).

20 foot units externally measure: 20 feet (6.1 meters) long, 8 feet (2.44 meters) wide, and 8 feet 6 inches (2.59 meters) high.

The internal dimensions of the containers may vary slightly depending on the construction.

The sides of a container are in nearly all cases, corrugated. The depth of the corrugation is usually 1 inch (25mm), which means that 2 inches (50mm) is lost from the external width dimension, giving an internal width of 7 feet 10 inches (2.38 meters).

The back (blank end) of the container is also corrugated and the doors are around 2 inches (50mm) thick meaning that approximately 3 inches (75mm) is lost from the length, giving an internal length of 19 feet 9 inches (6.02 meters).

The main reduction from external to internal dimensions is with height. The floor of a standard container has an underside clearance of approximately 6 inches (150mm) and the floor has a thickness of 27mm (1.1 inches). As the roof is corrugated another 1 inch (25mm) is lost resulting in an internal dimension of around 8 inches less than external – 7ft 10 inches (2.39 meters), though this can vary slightly depending on the flooring material used.

Through the door height is further reduced because of the steel top rail above the door which is a part of the structural integrity of the container, this is 4 inches (100mm) thus reducing the entrance height of a standard 20ft container to 7ft 6ins (2.28 meters), though this can vary slightly either way.

20ft External Dimensions Imperial Metric
Length 20 feet 6.1 meters
Width 8 feet 2.44 meters
Height 8 feet 6 inches 2.59 meters
20ft Internal Dimensions Imperial Metric
Length 19 feet 9 inches 6.02 meters
Width 7 feet 10 inches 2.38 meters
Height 7 feet 10 inches 2.39 meters

See our shipping container sizes page for more info on container dimensions.

What is the internal capacity of a 20ft container?

The internal storage capacity of a used 20ft is approx 33.2 cubic meters or 1,170 cubic feet.

How much does a used 20ft shipping container weigh?

There are three relevant weights relating to containers, the Tare Weight, the Gross Weight and the Payload (Net) Weight.

These are painted onto the outside of the container doors when it is in shipping service or before it has been repainted for another application.

The Container Tare Weight is the weight of the container without cargo or contents.

The Container Gross Weight is the weight of the container plus the maximum payload it can hold i.e. the maximum total weight of the container.

The Payload (or Net Weight) is the weight of the cargo or contents that a container can hold.

Typical 20 foot Container Weights Imperial Metric
Max Gross Weight 67,200 lbs 30,480 kg*
Tare Weight 4,780 lbs 2,170 kg
Payload (Net) Weight 62,420 lbs 28,310 kg

*some 20ft units are constructed to a lower specification - these lower grade containers have a max gross weight of 24,000kg

What are shipping containers made of?

20ft units are constructed using high quality weathering cor-ten steel which is designed to stand up to the harsh rigours of sea conditions. Due to the harsh environment they are all manufactured to a high standard and are both wind and water tight to protect their cargo.

Cor-ten is a corrosion resistant weathering steel, used within many industries for its strength.

High-quality rubber seals are used to prevent water ingress through the double-doors.

The internal flooring is typically formed from 27mm hardwood.

How long will a used shipping container last?

Used containers are approx 10 years old when sold, how long after the re-sale date will depend on how you use your container and the environment it's situated in.

A well cared for unit should last for many years (15+) after its re-sale date - see our care instructions for more information on caring for your container.

How will my used 20 foot container be delivered?

In order to offer the best possible price, we'll source your container from the depot offering the best price.

Your container will then typically be delivered from the depot on a HIAB Lorry. The lorry mounted craine will then be used to place your container into the pre-prepared location.

Please ensure you have prepared the ground prior to your container being delivered.

Please be sure to provide us with your delivery postcode as part of your initial enquiry so we can accurately estimate delivery costs.

Do I need to prepare the ground before my container is delivered?

Yes - Your container should to be placed on a flat level surface.

For uneven surfaces we recommend using paving slabs to create a level the surface.

We recommend using paving slabs to allow the four corner castings of your container to sit on a solid level base.

An uneven surface can result in the container not sitting straight, this can mean the container doors may not fully open and can cause the container body to twist.

The area for your shipping container will need to be prepared before our delivery driver arrives on site.

With our delivery drivers using a HIAB lorry, please check for any overhead cables as this can mean that the HIAB cannot extend its lifting arm out to lift the container to the ground.

If you are unsure if the HIAB lorry will have sufficient space to unload your container - please make us aware of any restrictions before placing your order.

Can I collect my used container?

Yes - please let us know if you are able to collect from one of our depots. Please note that unit prices do often vary from depot to depot so this could affect the price we are able to offer.

How do I look after my container?

Caring for a used container is mostly common sense, but there are a few things you can do to keep your box in a good condition.

Ensure the contents of your container are dry and moisture free before you put them inside - this will help reduce moisture build up inside your container.

Regularly check the double end door hinges and locking bars, apply oil to lubricate the hinges and locking bars to keep them moving freely.

Try to keep a little space free at the top of the unit and down the sides to allow the air to circulate. This helps heat to disperse and prevent moisture.

For more container care info check out our container care page.

Can I convert my used container?

Yes - 20ft shipping containers are often converted for uses other than shipping and basic secure storage. Take a look at our conversions page for some examples of our recent conversion projects.
