We Manufacture Your Steel Building Kits in the USA & Ship Direct...Worldwide!

Storage Unit Kits

Whether you are a business owner looking to expand your self-storage business, an entrepreneur wanting to start a self-storage company, or just someone with a passion for hobby vehicles and nowhere to store them, Worldwide Steel has you covered.

Worldwide Steel Buildings offers a wide range of metal self-storage and mini storage building kits that can be customized in all different building sizes, unit sizes, door styles and roof pitches to best fit your self-storage industry needs. We offer open storage units for RV and boat storage, and can handle any custom design needs you have in the most economical, high-quality mini storage building kits available.

High-Quality & Durable Storage Units

You don’t want to have to be checking on a storage building regularly to make sure it’s keeping the elements out and your belongings protected. When you invest in one of our steel building kits, you won’t have to. 

Worldwide Steel Buildings uses only high-quality American recycled steel, and our trusses are built on jig tables to maintain the same quality on every custom storage building and dipped in our rust inhibitor / primer tank to help your new mini storage buildings last for decades. Each truss is then inspected and pre-assembled to ensure that your new storage building goes together smoothly, the first time. This makes construction cost-effective, especially in comparison with the pricing of standard commercial building construction. 

Worldwide Steel Building is built to last, and we guarantee it. Our 50-year structural warranties, offered on every self-storage facility kit, sets us apart from the standard one- to two-year warranties offered by many other steel building companies. The premium sheet metal we use for siding on our commercial buildings also comes along with a 40-year warranty, giving you a low-maintenance storage building with the durability to last a lifetime.

Storage Building Customization

Not all commercial storage buildings or self-storage units are created equal. At Worldwide Steel, we know what you’re storing affects the requirements of your storage facility and even its building type. That’s why we make it easy to customize your building kit, at a low cost per square foot

Whether you need enough space for RV storage or just the room to keep some boxes, we have floor plans to fit your needs. If you need roll-up doors large enough for yachts or simple walk-through doors for small, affordable storage space, we can help you design your metal storage building kit that way.
