How to Stack Shipping Containers


Shipping containers are a versatile and durable solution for storage, transport — even housing. One of the many benefits of shipping containers is their ability to be stacked, which can save space and increase storage capacity. However, stacking shipping containers requires careful planning and execution to ensure safety and stability. Let’s explore how to stack shipping containers properly.

Choosing the Right Containers

The first step of any shipping container stack is to choose the right containers for your needs. Not all containers are created equal; some are better suited for stacking than others. Look for structurally sound containers free of major dents or damage. You should also consider the size and weight of the containers, as well as their condition and compatibility with stacking equipment.

When selecting your shipping containers, ensure they’re the same size and weight. This will help provide stability when stacking. You should also consider the condition of the containers, as any damage or wear could compromise their structural integrity when stacked.

It’s worth noting that wind and watertight shipping containers cannot be stacked. This is due to the heavy wear these containers have sustained during their many years of transporting goods at sea.

Stacking Your Shipping Containers

When it comes to stacking shipping containers, safety should always be your top priority. Before getting started, check that the ground is level and stable. Give yourself plenty of space to maneuver the containers with your equipment of choice. Use a crane or forklift to lift the containers into place, and ensure they’re properly aligned before lowering them onto the stack.

Stacking your containers in a way that distributes weight evenly will help prevent the containers from tipping or collapsing. To achieve this, stack the containers in a straight line and use twist locks or other locking mechanisms to secure them in place. Make sure that the locking mechanisms are properly engaged and that the containers cannot shift or slip.

How High Can You Stack Shipping Containers?

Most shipping containers suitable for stacking can be safely stacked up to 9 or 10 containers high. However, this can vary depending on the size and weight of the containers, the ground conditions, and the equipment you’re using to stack them.

It’s important to note that stacking shipping containers too high can increase the risk of collapse or tipping, which can be extremely dangerous. In addition, some local building codes and regulations may limit the height you can stack containers. Before stacking your containers, consult your local authority to ensure you comply with all relevant regulations and safety guidelines.

Maintaining Your Shipping Container Stack

Once you have stacked your shipping containers, it’s important to maintain them properly to ensure their stability and longevity. Conduct regular inspections to check for any signs of damage or wear. Any necessary repairs should be made promptly.

It’s also important to keep the containers clean and free of debris, as this can impact their stability and safety. This includes regularly removing any water or snow that accumulates on the containers, as well as checking for any rust or corrosion that may compromise their structural integrity.


Stacking shipping containers can be a great way to increase your storage capacity and make the most of your available space. However, it’s important to approach the task with caution and careful planning. By choosing the right containers, stacking them properly, and maintaining them regularly, you can enjoy the benefits of stacked shipping containers safely and effectively. With the right precautions in place, you can stack your containers with confidence and peace of mind.
