Weather Resistant Shipping Containers

Weather Resistant Shipping Containers


When a shipping container is initially built, it is constructed to certain standards.  These standards create a weather-resistant cargo box. Shipping containers travel through all types of weather.  They also travel long distances.  In fact, some travel across oceans. Weather resistant shipping containers must be able to withstand rain, ice, snow, high winds, and rapid temperature changes. Additionally, they must protect the cargo within. 

The solid build of shipping containers and their weather-resistant properties are two of the leading reasons that people repurpose these containers. 

Weather Resistant Shipping Containers Considerations

Once construction starts, the certification changes.

All shipping containers must be certified as weather resistant when first constructed.  This happens before they are allowed to be filled with cargo. Shipping companies use weather resistant shipping containers that have been certified to guarantee to their clients that the freight will be protected. 

However, once Portables 360 begins making modifications to your container, it is no longer considered weather resistant certified. 

This does not mean that your new structure will not have the durability of a safe and sturdy structure. It also does not mean that the structure will not be protected from rain, wind, or other harsh weather conditions. Losing this certification means that the changes to the container’s structure no longer allows it to be classified as a weather resistant cargo container that can be used to transport goods. 

When Portables 360 alters a shipping container for their clients, they make sure that the container still retains structural integrity.  Additionally, they ensure its ability to withstand weather is intact. Even with the addition of windows or doors to the container’s side, Portables 360 will add the right protections to ensure that the container is structurally sound and weather resistant. 

Recertifying Your Shipping Container 

If you would like to transport your container overseas in the future, you can have it recertified through the Approved Continuous Examination Program at the port. However, unless you are using the container for shipping goods, this is probably not necessary. 

If you are shipping your modified container overseas, it is probably in your best interest to ship it as merchandise instead of as a shipping container. In this way, it will be placed in the cargo hold of the ship, protected from the weather and other conditions, and will arrive safely without the added expense of certification. 



Stacking Shipping Containers Safely

Stacking Shipping Containers Safely

When you are moving cargo on a ship, stacking shipping containers is very easy. Containers are specially designed to fit securely on top of each other.  They can be stacked up to nine containers high. The corners of the containers are reinforced.  This ensures the containers stay in place during their journey. 

However, when you are stacking modified containers to create a multi-container structure, you must take more precautions.  Safety must be your priority when stacking the containers.  Safely stacking will ensure they retain their structural integrity. 

To safely construct a multi-container unit, Portables 360 uses the following guideline for stacking shipping containers: 

Stacking Shipping Containers Safely 

If the construction site where the containers will be stacked is prepared, our service techs will stack the containers immediately. The containers will be removed from the trucks in the order that they are required to construct the building.  They will be placed in  correct position. 

In most cases, we recommend that a crane is used for stacking the containers. Straps are placed at the four corners of each container.  Next, they are safely lifted and placed in position. Using a crane provides extra safety measures. Cranes can suspend the container until it is placed perfectly.

On some occasions, a heavy-duty forklift can be used for stacking containers. If a forklift is used, it must be rated for the weight limits of the containers.  Additionally, it must have the capability of lifting the container up high enough to be stacked.  Finally, it must be operated by an experienced technician. Using a forklift can be beneficial.  Ask us the best way to stack your shipping containers.

Securing the Shipping Containers Properly

When you are constructing a multi-level container building, it will be necessary to secure the base containers to the foundation.  This creates extra strength and security. Once we have secured the bottom containers, each container that is placed on top is secured in order. 

We use a locking system to connect our containers. This is the most secure connecting method to use on our container systems. These connections are placed at the corners of each container as well as any other key spot to help with structural integrity. 

Final Securing Measures 

Once the structures have been locked together, our crew will make sure that the containers are protected from the weather. To do this, we will caulk all seams. This protects the containers from water entering the containers and gives added strength to the structure.  A waterproof structure is an extremely important benefit to a shipping container structure.

We will also add flashing to the containers.  The added roof cap will deflect rainwater and snow. These finishing touches give your container the extra protection it needs to last. 

Once all of these tasks have been completed, the next steps in construction, such as electrical and plumbing installation, can begin. 


Dry Ice & Cold Storage

Dry Ice & Cold Storage

There are many occasions where the use of dry ice and cold storage are beneficial. Businesses need to store food products in controlled temperatures, storage of medications and temperature-controlled storage of certain types of beverages are a few of the uses for a cold storage system. 

Portable containers are an affordable solution for cold storage. There are many dry ice benefits such as keeping temperatures below freezing or filling empty space in a cold storage container. Additional dry ice benefits include having the ice available when you need to ship small packages that require the temperature to remain steady for your customers. Air conditioning can also be installed into these units.  This is perfect if you need a steady temperature that is not below the freezing mark. 

A cold storage container can be placed anywhere on a property as long as the ground is level.  They are easy to move when necessary. Portable shipping containers can also be used to transport cold goods and dry ice to areas in need.  Disaster zones or areas suffering from extreme temperatures benefit immensely. 

Why Do Shipping Containers Make Good Cold Storage Units? 

One of the main reasons that shipping containers make such good cold storage units is because of how well they seal. The containers were originally designed to move merchandise across the globe on a ship. Ships are exposed to wind, water, and all kinds of weather conditions.  Because of this, containers have been constructed to seal tightly.  This ensures water and air cannot enter the container and cause merchandise harm. 

Once converted into a cold storage unit, containers retain the ability to stay sealed.  This ensures the temperature stays consistent within the unit. Dry ice and regular frozen or refrigerated goods can maintain an even temperature easily when they are placed in a refrigerated shipping container. 

Portables 360 will help you select the right shipping container to convert into a cold storage unit. We offer a variety of sizes.  Additionally, we will make any alterations to the container you feel necessary.  Your business will benefit from your cold storage unit.
