Joining Up Shipping Containers

Need an extra wide shipping container? Shipping containers are often used as the basic structure for shipping container conversion projects i.e. shipping container offices, clubhouses, garages, classrooms, welfare cabins, workshops etc. They make the perfect secure, anti-vandal site accommodation, but as shipping containers are manufactured in a standard width of 8ft, this can sometimes prove restricting if a larger space is required. Containers Direct can build brand new containers to give you a width of up to 14ft, but if you need something really wide they are too big to transport as a whole. Our solution to this is joining up shipping containers, side by side, to give a width of 16ft, 24ft or even 32ft. We prepare these containers in our workshops, transport them as individual units, and then join them together on site. Work can be carried out using both new shipping containers and used shipping containers.



How we join containers

  1. First we remove the full long sides of the containers.

  2. Depending on the length of the containers required, we can either retain 350mm on each side of the aperture to provide strength to the container and reinforce the aperture with box section steel, or we can create a supporting post(s) in the middle of the container which are reinforced with box section steel to stop the roof from dropping down.

  3. The containers are then joined together. We usually secure them with bolts to prevent any movement.

  4. We provide our customers with a PVC "Top Hat" and flash-banding to seal the two units together. We can provide an installation service if required. Similarly, some customers prefer to weld the containers together once in place on site.

For detailed instructions on how to join your containers on site, please click here.

For conversions with the upright supporting pillars removed/no retained corrugation to allow for the full open space, a far more heavy duty box section steel is required to reinforce the top rail, in order to support the roof section (£POA).

Case studies

See examples of our work carried out at Containers Direct using joined up containers. We can use any length as a starting point, from 10ft shipping containers up to 40ft shipping containers. We have worked with widths of up to 32ft and we can make whatever you need. Extra wide container garages are very popular as they allow plenty of room for parked cars and additional storage space.



Joined up office conversions

For any office conversions, we would always recommend Melamine lining and insulation and an Electrical Installation (these can be quoted on depending on your specifications). Steel personnel doors and shuttered windows are also favourites, however we are also able to provide a range of patio style doors, sliding doors and bifold doors upon request. Additional popular features include partition walls, and fixtures and fittings such as toilets and kitchen facilities.

Optional Extras

We offer a range of optional extras for all our shipping containers to help ensure your container is perfect for you.




Extra wide storage space

Joining shipping containers together can also be used to achieve an extended storage area, in which case the normal selection of features available with converted storage containers apply:

  • Repainting - choose from a large range of colours

  • Lining and Insulation - Fully insulates your container to protect against condensation. We can provide both Ply lining and Melamine lining depending upon the specification required.

  • Grafotherm - applied to the ceiling of the container to help reduce condensation.
You also have a choice of door styles:
  • S1 Storage container doors, which are much lighter and easier to handle than shipping container doors
  • S2 Original shipping container doors, which are heavy duty and rubber sealed
  • S3 Storage container doors, which are lightweight and include a rubber seal.
  • S4 Roller Shutter Doors, a good alternative when space is restricted.




These door options are also available in the side to provide access in the length of the container. To learn more about our joined up containers, give us a call or view our Case Studies for more ideas!
