Steps to connect two shipping containers

Numerous methods are available for you to connect two shipping containers. Out of them, the best method available for you to follow is to use roofing cement along with welded corner posts and thin sheets of metal.

  • Weld the two containers

You will need to keep the two containers side by side and proceed with welding. You need to weld them carefully to the foundation as per your plan. Then you will be able to apply roofing cement. But before that, you should install a rolled roof flashing inside as well as outside the opening. This will help you to create the best seal.

  • Fill in the gap with a sealant

After you merge the two shipping containers, there will be a small gap left in between them. You can apply a sealant to fill it up. Duritan is a perfect example of such a sealer. You will be able to buy it from one of the local hardware stores.

  • Ensure that load is distributed correctly

If you have any plans to stack up shipping containers to get more roofing space, you need to make sure that the load is going through corner posts. Then the weight should be transferred properly to the foundation. You will also come across the need to remove side panels as per your needs. While doing that, make sure that you don’t lose the integrity of your home. The side rails will not have enough strength and you should be mindful when you are dealing with them.

All the steel welds you use for connecting two shipping containers should be at least 4×4. Then you can ensure the strength and structural stability of your shipping container home.

Important Tips:

There are some important things you need to keep in mind when connecting two shipping container homes as well.

  • Seal the two units properly

You should make sure that you are sealing the two units you connect. Along with that, you can prevent water leaks from taking place.

  • Ensure that your foundation is properly leveled

On the other hand, you should also ensure that your foundation is perfectly leveled as well. You can use ropes and make sure that the foundation is properly leveled. Otherwise, you will run into numerous structural issues.

  • Ensure that the protruding corner posts are properly sealed

All the protruding corner posts of the shipping container must be perfectly sealed when they are stacked side by side.

  • Have a clear understanding of the structure

You must always have a perfect understanding of the structure of the container home that you are building. In other words, you need to be aware of how physics works. The two long walls of a container are bracing and load-bearing. If you are planning to create a hole in any of them, you should ensure that it has to be compensated.

By keeping these things in mind, you can get the most out of your container home connecting process.
