Finding conex storage containers for sale is more than just a purchase; it’s a strategic investment in durability, mobility, and long-term value.
Businesses, contractors, homeowners, and creative professionals are repurposing these steel containers into versatile storage spaces, workstations, and even commercial venues.
In a world that demands speed and reliability, shipping containers offer a solid, portable, and secure solution for a wide range of industries.
What Are Conex Storage Containers?
Conex containers, short for “Container Express,” were first developed by the U.S. military in the 1950s for safe and efficient transport. Today, they’re widely used across commercial, industrial, and residential sectors.
Made from heavy-duty corten steel, these containers are built to resist corrosion, withstand extreme weather, and endure years of use without structural damage.
Their universal appeal lies in their simplicity. With a rectangular design, reinforced frame, and secure locking system, they offer instant storage anywhere you need it.
What Makes Conex Containers Different from Other Storage Units?
Unlike traditional wooden sheds or portable buildings, conex boxes are stackable, forklift-friendly, and practically indestructible.
They don’t warp, buckle, or leak when exposed to the elements. You can use them on a construction site, on farmland, in a parking lot, or behind a retail business with zero structural compromise.
Why It’s Smarter to Buy a Conex Storage Container Instead of Renting?
Buying a shipping container is a long-term investment in flexibility and control.
Renting might seem more affordable at first, but over time, the monthly fees add up, and you still don’t own the unit.
When you buy, you gain full freedom to customize, move, resell, or repurpose the container at any time without penalty.
Ownership Unlocks More Options
Most buyers choose from three common shipping container sizes:
With ownership, you can install insulation, build shelving, mount HVAC systems, or even convert it into a pop-up business or office.
More importantly, there are no limits on how long or where you can use it. Your investment becomes a tangible asset that works for you.
Choosing the Right Conex Storage Container Size and Type
Before browsing conex storage containers for sale, it’s essential to evaluate your space, budget, and intended use.
Standard Conex Container Sizes Available
10-Foot Conex Storage Containers
10-foot shipping containers are the go-to solution when you need secure storage but have limited space to work with. Their compact size makes them ideal for residential areas, apartment complexes, small business sites, or urban locations where space is at a premium.
Despite their smaller footprint, they still offer ample room for storing household items, seasonal decorations, yard tools, or overflow from a garage. These containers are also easy to relocate, making them a favorite for temporary projects, pop-up shops, or mobile storage needs.
20-Foot Conex Storage Containers
With approximately 1,165 cubic feet of storage space, 20-foot shipping containers strike the perfect balance between size and utility.
They’re large enough to store a wide variety of items such as construction tools, machinery, building materials, retail inventory, or personal belongings during a move, while still being small enough to fit in most driveways or job sites.
Their standardized dimensions also make them easy to transport by truck, rail, or ship. Its durability and versatility make it one of the most commonly used container sizes across industries.
40-Foot Conex Storage Containers
Offering around 2,385 cubic feet of interior space, 40-foot containers are ideal for storing bulkier, high-volume items.
These units are popular among logistics companies, manufacturers, agricultural businesses, and automotive operations due to their ability to house large equipment, vehicles, bulk materials, or expansive inventory loads.
Their extra length allows for better organization of stored goods, especially when using shelving or container accessories. Despite their size, they remain easy to transport and stack, making them suitable for long-term storage, overseas shipping, or setting up large-scale modular structures.
Specialized Container Types
Beyond the standard dry container, you can choose from:
High Cube Conex Storage Containers
High cube containers are similar in length and width to standard containers, but they stand one foot taller, typically 9.5 feet high instead of the standard 8.5 feet.
That added vertical space makes a big difference when you need to store tall equipment, stack goods higher, or create a more spacious interior layout.
These containers are especially useful for storing or transporting bulky items, oversized furniture, and large machinery that wouldn’t fit in a standard-height unit.
Refrigerated Conex Storage Containers (Reefer)
Reefer containers, short for refrigerated containers, are equipped with built-in cooling systems to maintain precise temperatures throughout the journey or storage period.
These containers can typically maintain internal temperatures ranging from -30°C to +30°C (-22°F to +86°F), depending on the model.
With their reliable insulation and temperature control, reefer containers are widely used in the food industry, medical supply chains, and even flower distribution centers.
Open-Side Conex Storage Containers
Open-side containers feature full-length side doors that swing open to provide much wider access than traditional end-opening units.
This unique design makes it easier to load or unload awkward, oversized, or long items that wouldn’t fit as easily through the front doors.
The side opening also allows for better organization and easier access to goods, especially when the container is used as a semi-permanent storage or work area.

Additional Expenses to Consider
Factor in delivery fees, modification costs (lockboxes, doors), and site preparation if required.
Bundling multiple containers not only simplifies logistics, but it can also lead to significant savings. Buying in bulk often qualifies you for volume discounts or reduced transport rates, making it a cost-effective option for businesses managing large-scale storage or expansion projects.

Key Features to Inspect Before Buying
Inspecting container quality is essential to ensure your investment is durable, secure, and long-lasting. Taking time to assess the condition upfront can help you avoid unexpected repairs or costly replacements down the line.
Must-Have Conex Storage Container Condition Markers
When evaluating used shipping containers, pay close attention to the following key features:
✔ Watertight Seal
Make sure the container is completely sealed. Stand inside with the doors shut and check for any visible holes or light seeping through, which may indicate leaks. Inspect the roof and corners, as these are common areas for wear and tear.
✔ Fully Functional Doors and Locking Bars
Test the doors by opening and closing them fully. The locking bars should move smoothly without excessive force. Bent or rusted hinges can affect security and usability, so make sure they operate properly.
✔ Solid, Clean Flooring
Check that the wooden or steel flooring is intact, with no soft spots, warping, or rot. A sturdy floor is essential if you’ll be storing heavy equipment or converting the unit for structural use.
✔ Minor Surface Rust Is Fine, But Avoid Deep Corrosion
Surface rust is common and usually harmless. However, deep corrosion, bubbling, or flaking paint may suggest long-term exposure to moisture and could weaken the container’s structure. Be cautious of dents that may trap water.
Refurbished Containers – A Great Middle Ground
If you’re concerned about looks and functionality, refurbished shipping containers can be a smart choice.
These units are professionally cleaned, repainted, and resealed to restore appearance and performance. They’re especially ideal for businesses, schools, or residential projects where visual appeal matters as much as function.
