30ft Shipping Containers For Sale
Explore our 30ft shipping containers for sale across the UK. These mid-sized units offer a practical balance between storage capacity and footprint, making them ideal for sites where a 40ft container is too large but a 20ft unit does not provide enough space.
Built from modified 40ft units, 30ft units deliver secure, wind and watertight storage for a wide range of commercial, industrial and on-site applications. Compared to standard container sizes, 30ft units offer greater flexibility for sites with specific space or capacity requirements.
Overview
30ft shipping containers are not a standard size, but are instead created by cutting down a 40ft container.
These containers offer a practical middle ground in terms of size, providing more capacity than a 20ft unit while requiring less space than a 40ft container. They are used across a wide range of industries, particularly where space constraints and storage requirements need to be carefully balanced.
Commonly used for general storage, 30ft containers can also be repurposed and converted into bespoke projects such as workshops, bars, restaurants, COSHH stores and much more.
Our used 30ft shipping containers are built with plywood flooring, multiple air vents and lashing points as standard. All 30ft units are guaranteed wind and watertight too, giving you peace of mind that all contents inside will be protected. If you require a 30ft shipping container to be made from a new (one trip) unit, it will also come with a lock box - this feature can be added as an optional extra on used boxes.
The size and versatility of our 30ft units are appealing factor, as they provide more space than a 20ft container and less than a 40ft container if space is limited.
Please note that the dimensions of a standard 30ft shipping container can vary because of the fact they are modified.

FAQ
30ft containers are less common because they are not manufactured as a standard size. Instead, they are created by modifying 40ft containers, which means availability can be more limited compared to standard 20ft and 40ft units.
When selecting a 30ft container, it is important to consider available space on site, access for delivery, required storage capacity and whether a standard or high cube configuration is needed. As these units are modified, confirming exact dimensions before purchase is also recommended. There is also the additional cost of labour required to cut down and modify a 40ft container.
The tare weight (weight when empty) of a 30ft standard shipping container is approximately 2,900-3,200 kg. As these containers are created by modifying larger units, the exact weight may vary depending on the original structure and specification.
A 30ft container is often chosen when a 20ft unit does not provide enough capacity, but space limitations prevent the use of a full 40ft container. This makes it a practical solution for sites with restricted layouts or specific storage requirements.
Yes, 30ft containers retain the same steel construction and durability as the original 40ft units they are created from. When properly modified and maintained, they provide the same level of weather resistance and structural strength as standard containers.
A 30ft shipping container is a modified storage unit created by reducing the length of a standard 40ft container. It provides a balance between storage capacity and space efficiency, making it suitable for locations where standard container sizes are not ideal.
