40ft Portable Storage Containers

When it comes to portable storage units, not all containers are created equal. 


Our 40ft storage containers are our storage warriors. These units offer enough storage space for medium to large-sized jobs, giving you the strength and versatility to protect your most valuable commercial equipment and supplies. And since they’re made from corrugated steel, our 40ft shipping containers are virtually indestructible.


If you’re thinking about renting a 40ft container, you’ve come to the right place. We have all the information you need to assess how they can help you, your team, and your business. 

What Is a 40ft Container?


40ft storage containers are one unit type with many names. At Mobile Mini, we commonly refer to these units as 40ft containers and 40ft shipping containers. No matter what you call them, 40ft storage containers are standalone portable storage units that give you the storage space to house the construction equipment, documents and records, and other business supplies that keep your daily operations in check. 


All of the storage units at Mobile Mini are repurposed shipping containers. Our 40ft storage containers have shed their maritime past, but have kept their existing portability, strength, and durability. Like shipping containers, our 40ft units are designed to move, giving you the freedom to store commercial goods across multiple project sites without worrying about structural or physical integrity.

A clearance of 120 linear feet is required for our 40’ containers. Our trucks require a 21’ vertical clearance for loading and unloading containers. We can provide a free site check, where one of our drivers will come out and determine the most appropriate location. 

Premium Single Entry
For simple access to your stored items, a single entry will control access to only those with the key. Mobile Mini’s premium doors allows access with one hand for ease and convenience.


Premium Double Entry
For more access to your stored items, a double set-up is great for accessing items on a regular basis. This setup is perfect for sharing a space with another party so each party has their own side to access. Mobile Mini’s premium doors allows access with one hand for ease and convenience.


Brackets and Rails for Shelving
Our customized brackets and rails shelving system is available as one of our permanent portable storage options. Brackets and Rails can accommodate shelves of different widths at any height. (Brackets and rails are not available at all locations.)


A container ramp makes moving in and out of storage containers with handcarts quick and easy. Each container ramp is coated with a non-slip surface and painted orange for safety. (Ramps are not available at all locations.)


Whether you need one unit or a hundred across the country, our dedicated drivers will swiftly and carefully deliver your unit directly to your door, and help you find the safest and most convenient place to put it on your site. They can even help show you how to use the specific features on your unit if you need assistance. Because we own trucks we are a reliable and cost-effective solution.



For customers with long-term logistical needs, we can relocate your empty container to your next jobsite. This additional solution makes us more flexible and responsive to meet your needs. It can also means extra savings for you.

Why Choose a 40-Foot Shipping Container? 


A better question is, why wouldn’t you choose a 40ft shipping container to handle your commercial storage needs? When it comes to our standard-width storage units, it doesn’t get bigger than our 40-foot shipping containers. These units work best for medium to large storage jobs and can easily house construction equipment and other commercial supplies that have standard widths and dimensions. 

One of the best and most convenient aspects of our 40ft storage containers is that we have designed these units to fit within the confines of a standard parking space. This means that you can easily house your storage unit on-site without taking up valuable space and commercial square footage.

Benefits of a 40ft Shipping Container


The top five benefits these storage containers bring with them include:

  • 100% Secure: When it comes to your business, security is a top concern. Our 40 ft storage containers come standard with Mobile Mini’s patented tri-cam locking system. We designed this locking system to seamlessly integrate into our units, providing locks that cannot be cut, picked, hacked, or tampered with. These locks ensure that thieves stay out of your equipment and that the only way into your unit is with a key. Period. 
  • Fully Weatherproof: All of Mobile Mini’s portable storage units, including our 40ft containers, are 100% weatherproof and designed to withstand heavy rain and snow, intense wind, sleet, hail, and even natural disasters. Our units are moisture sealed, which means that water and condensation will stay away from your valuable supplies. They also come with a stable frame and durable exterior, so you never have to worry about your unit caving to Mother Nature. 
  • Highly PortableOur 40-foot shipping containers are highly portable and can be easily transported from jobsite to jobsite. That’s great news for companies that work across multiple cities or states.
