40ft Shipping Container Construction

A used 40ft shipping container should last you 20 years plus, with a little maintenance. This is down to the robust construction process and the exterior material; containers are manufactured using high-quality corten steel. Cor-ten steel is a heavy duty, weathering, corrosion resistant steel which is ideal to withstand the harsh rigours of sea conditions.

When we first receive a used/second-hand shipping container at one of our depots, they are inspected to ensure they are structurally sound and fully wind and water tight; we make sure they are up to the cargo worthy industry standard. The double doors are inspected to make sure they are fully operational and the seals that run around the double doors are fully intact to prevent any water ingress. The flooring of a shipping container is made from 27mm hardwood.

Our used 40ft shipping containers will be typically 10-15 years old from the date of manufacture. They are typically used to transport cargo across seas for several years by leasing companies before being released for sale second hand.

Our 40ft used containers are usually picked from our depots on a “next from stack” basis, so the external colour will be a generic shipping line colour, which may vary.

If you require your container for shipping overseas, then we can update the details on the CSC plate, this re-certifies the container to allow it to be used for shipping (please advise us if this is a requirement when placing your order).

Important Questions you should ask about Used 40-ft Shipping Containers

What are the dimensions of 40-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: 40 feet (12.2 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 39 feet 5 inches (12.03 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 40ft container to 7ft 6ins (2.28 meters), though this can vary slightly either way.

40ft External Dimensions Imperial Metric
Length 40 feet 12.2 meters
Width 8 feet 2.44 meters
Height 8 feet 6 inches 2.59 meters
40ft Internal Dimensions Imperial Metric
Length 39 feet 5 inches 12.03 meters
Width 7 feet 10 inches 2.38 meters
Height 7 feet 10 inches 2.39 meters

What is the internal capacity of a 40ft container?

The internal storage capacity of a used 40ft is approx 67.6 cubic meters or 2,387 cubic feet.

How much does a 40ft 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 40 foot Container Weights Imperial Metric
Max Gross Weight 67,200 lbs 30,400 kg*
Tare Weight 8270 lbs 3,750 kg
Payload (Net) Weight 58,930 lbs 26,730 kg

*some 40ft units are constructed to a lower specification.

Where are used 40-ft containers sourced from?

New Containers are initially manufactured in the far-east, they then begin life as shipping containers, typically used for approx 10-15 years before being re-sold on from various ports/container depots to the used container market.

The date each container was originally manufactured is clearly stated on the CSC plate, located on the double doors.

We buy used containers from many shipping container depots, check they're in good used condition, wind and watertight - then deliver them to our customers.

What are shipping containers made of?

40ft units are constructed using high quality weathering cor-ten steel which is designed to stand up to the harsh sea conditions. Due to the environment they are all manufactured to a high standard and are 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?

This will depend on how you use your container and the environment it's situated in.

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

How will my 40 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 on 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.

Please also take into consideration any limitations of your location, the Crane will only be able to position your container within a close proximity to the vehicle.

If you have any concerns with regards to delivery at your location, please let us know.

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

This depends on your intended use, but generally, 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 container?

Yes - please let us know if you are able to collect your used container from one of our depots. Please note that used 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 used container?

Caring for a 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 - 40ft's are often converted for uses other than shipping and basic materials storage. Take a look at our conversions page for some examples of our recent conversion projects.

Common conversions include the installation of personnel doors, or roller shutters, adding windows or serving hatches, installing electrics, internal lighting and internal cladding
