Metal Storage Buildings


People are trusting you to keep their memories safe. Trust us to help you do just that.

Whether you’re storing your own expensive equipment like RVs, agricultural machines, or even aircraft or shopping for a building to provide commercial storage space, you want to ensure you’re getting an affordable and durable building to protect those assets adequately. Our American-made metal building kits are designed and manufactured with simplicity, longevity, and affordability in mind. Moreover, each building is designed specifically for our customers. So, you can rest assured that you’ll get the exact building you need delivered on time and manufactured with the utmost quality.

At Great Western, we take pride in our product.

Every building we deliver comes with a lifetime structural warranty. Our expert engineers have decades of experience designing buildings to meet International Building Code (IBC) standards, ensuring that each building we ship is ready for its intended climate. With considerations like wind resistance, snow load capabilities, and seismic activity accounted for, our buildings are engineered to last and adequately protect whatever is stored inside them.

In addition, our buildings are engineered for simple erection with the DIY-er in mind, and we provide our customers with an industry-leading erection manual that is comprehensive and in-depth. We also offer a 24/7 customer support hotline to help field any questions that may arise from the design phase to construction. 

Why Go With Great Western? 

Our designers can provide a precisely engineered building specific to your location and size needs. At Great Western, no project is too big or too small for our undivided attention. We’ll work with you and your budget to ensure you get exactly what you want. In addition, we offer deep levels of customization, like over a dozen color choices, oversized or small storage space options, stand-alone or adjoined units, multi-story facilities, and even engineering for climate-controlled storage buildings. Whether you’re looking for large-scale storage for things like RVs, agricultural equipment, and machines or a small personal storage structure for your small business, a Great Western building is the perfect solution. 

One of the most significant advantages of a steel building for your storage solution is its clear-span framing. There are no support columns to interrupt the usable space in the building’s interior, which means you’ve got wall-to-wall usability. With options like oversize doors, Great Western can provide a building to store virtually anything. From multi-vehicle storage to aircraft and industrial storage, our buildings make the perfect solution. Moreover, the robust nature of steel means you’re getting a long-lasting and dependable building that requires little to no maintenance.

Your building is designed specifically to suit your needs and location. If you’re unsure what size building you need, our team can help you decide based on your plans. Whether you’re looking for personal storage or a commercial storage operation, our team of designers can ensure you get the perfect solution. 


How Much is a Storage Building from Great Western? 

Typically, our buildings start between $15 and $20 per square foot. Of course, the price is variable depending on your project specifications. Building size is a factor, as you’d expect. Additional factors like necessary climate reinforcements require more material and can raise the cost of your building. Of course, custom design choices like multi-level roofs and adding a substantial amount of doors increase the price of your building. 

Ultimately, the best way to get an accurate estimate of the cost of your unique building is to request a free quote from Great Western directly. If you’d like, you can use our 3D Building Designer to create a preliminary design of your building. This allows you to visualize everything from your aesthetic choices down to door and window placement. Once you’ve completed your design, you can submit it to our expert team, and we’ll contact you with your estimate.

Why Choose Great Western?

Our experienced engineers know the awesome responsibility you’re up against. We also know that units need to be durable enough to withstand multiple use, and a constant barrage of traffic – in and out, all the time. People want access to their valuables and they may not be as respectful to the structure as you are to their possessions, so the units need to withstand use and abuse.

With simple tools and components that are designed and produced to fit perfectly, you can be assured that the costly or annoying jobsite adjustments that a traditionally constructed building might require can be avoided – allowing you to serve your customers in a fraction of the time.

With Great Western’s easy to read erection manuals and 24/7 support line, you can feel comfortable that you’re not getting yourself into something you can’t handle. Our team not only sells and designs pre-fabricated steel buildings, but we also build them! Your sales team’s been in the field, they’ve been in the fabrication facilities, and they know, first hand, what to expect during the erection process.

Frequently Asked Questions

Do Great Western steel storage buildings need a footer-style foundation?

In most cases, a simple Alaskan Slab is sufficient for your Great Western metal building kit. Of course, this depends on your job site’s soil conditions. The best way to get a definitive answer on your concrete needs is to discuss it with a concrete contractor once you’ve finalized your building design with your team. We’re happy to work with your concrete supplier to discuss the building’s needs.

Does our metal storage building need insulation?

We recommend the installation of insulation in every Great Western steel building. Proper insulation prevents condensation within the interior panels and secondary framing of your building. Without insulation, your building could experience premature corrosion from accumulating moisture. We offer cost-effective insulation solutions for your metal building kit that are simple to install and can increase your building’s resale value.

If our building is used for manufacturing or storage and that process uses, stores, or creates corrosive products, will this void any of our warranties?

Notify your Great Western representative of any chemicals that may come in contact with your steel building structure. A handful of products at your disposal can limit or protect your building from direct exposure to harmful chemicals and materials. However, if your building is exposed to an abnormally corrosive environment and there are no proper maintenance procedures enacted or preventative measures taken, there is a good chance that it will fall outside of your warranty. We provide customers with a complete maintenance guide and log of each building we manufacture upon request, which can help ensure you’re taking proper care of your steel structure. Discussing these potential corrosion issues with our team up front can help clarify whether or not your warranty will be voided.

Mini-storage units take a lot of abuse, how difficult is it to get replacement parts?

Simple! Great Western can provide milk-run type delivery throughout the lower 48 States. We have numerous vendor partners across the county that can provide replacement panels, doors, fasteners, trims and accessories in the same colors and profiles as your building.

What’s the difference between a mini-storage building and these buildings?

Mini-storage buildings are interchangeable with the term “self-storage” building and refer to commercial buildings with dozens of independently leased storage units. They are typically used for storing extra boxes, furniture, and other personal belongings after a move. Our commercial storage buildings are usually used for more extensive storage operations for things like RVs, Cars, Boats, heavy machinery, and even aircraft.


Great Western’s custom design tool allows you to design, customize, and price the best metal building for your needs. You can also share and print your designs or save them and modify them later.
