What Is a Conex Container With a Roll Up Door?
A Conex container with a roll-up door is a Corten-steel shipping container equipped with an overhead door that opens by rolling straight up along interior tracks and tucking away overhead. “Conex” is industry shorthand for a steel intermodal shipping container; the roll-up door is a modification that replaces or supplements the traditional swing-out cargo doors.
The defining difference is access. Standard cargo doors are two large panels that swing outward on hinges and require open clearance in front of the container. A roll-up door needs no swing clearance at all, so the container can sit in tighter spaces while still offering a full, unobstructed opening every time you load or unload.
Why Roll Up Doors Change How You Use a Container
The roll-up door is the single feature that determines whether a container is convenient for high-frequency use. If you open your container several times a day, the difference between a swing door and a roll-up door compounds quickly.
- Full-width, swing-free access: the door clears the entire opening, so nothing blocks a forklift, cart, or pallet jack from driving straight in.
- Tighter placement: with no outward swing, the container fits against walls, fences, or other units without leaving room for doors to open.
- Faster loading cycles: there are no panels to unlatch, swing, and secure on each trip, which saves time on busy job sites.
- Better organization on multi-door units: a 40 Foot container with roll-up doors lets you separate inventory into compartments, each with its own access point.
Types of Roll-Up Door Containers Available
Aztec Container builds roll-up door configurations across all three standard container lengths. The right choice depends on how much volume you need and how many separate access points the layout requires.
| Container Type | External Dimensions | Best For |
| 10 Foot Roll Up Door Container | 10′ L × 8′ W × 8′ 6″ H | Compact sites, residential storage, small-tool and equipment access where space is limited |
| 20 Foot Roll Up Door Container | 20′ L × 8′ W × 8′ 6″ H | The most common size: construction supplies, warehouse overflow, mobile workshops, general commercial and home storage |
| 40 Foot Container, 1 Roll Up Door | 40′ L × 8′ W × 8′ 6″ H | Maximum single-compartment volume with one wide access point at the front |
| 40 Foot Container, 2 Roll Up Doors | 40′ L × 8′ W × 8′ 6″ H | Splitting one long container into two access zones for organized inventory |
| 40 Foot Container, 3 Roll Up Doors | 40′ L × 8′ W × 8′ 6″ H | Three separate access points along the unit for multi-team or multi-category storage |
| 40 Foot Container, 4 Roll Up Doors | 40′ L × 8′ W × 8′ 6″ H | Maximum access and flexibility: four compartments, ideal for high-traffic operations needing frequent entry at several points |
How These Containers Are Built?
Every Aztec roll-up door container is built on the same heavy-gauge steel platform regardless of size:
- Walls: 14-gauge corrugated Corten (corrosion-resistant) steel
- Frame: heavy 8-gauge steel
- Flooring: marine-grade plywood roughly one inch thick, mounted on steel cross-members, rated for heavy loads and forklift traffic
- Door: overhead roll-up door on vertical tracks
- Security: steel lockbox that shields the padlock and resists tampering
- Ventilation: built-in vents to promote interior airflow
- Customization: modifications available to fit specific use cases
What People Use Roll Up Door Containers For?
Because the roll-up door makes frequent access easy, these containers suit any operation where goods or equipment move in and out regularly:
- On-site storage for building and construction supplies
- Equipment and tool storage with quick daily access
- Warehouse overflow and inventory staging
- Mobile workshops and job-site operations
- Commercial and home storage needs
- Multi-compartment storage (on 2, 3, or 4-door 40ft units) for separating teams, trades, or product categories
Roll Up Door vs Cargo Door vs Walk-In Door
| Door Type | How It Opens | Best Suited To |
| Roll-up door | Lifts vertically along overhead tracks; no swing clearance | Frequent loading/unloading, forklift and pallet access |
| Cargo door | Two steel panels swing outward on hinges | Sealed long-term storage; less frequent access |
| Walk-in door | Standard hinged personnel door, like a building door | Easy human entry; often combined with a roll up or cargo door |
Buying vs Renting
Both options are available. Renting suits temporary projects and short-term needs, while buying makes sense for ongoing or permanent storage. Sales are offered nationwide, and rentals are available throughout California. Pricing varies by size, door configuration, whether the unit is new or used, and your location, so the most accurate way to compare options is a direct quote.

Frequently Asked Questions
What is a Conex container with a roll-up door?
It’s a steel shipping container fitted with an overhead door that rolls straight up along tracks instead of swinging outward like standard cargo doors. “Conex” just means a steel intermodal shipping container, and the roll-up door is the access upgrade. The big advantage is that you get a full-width opening with nothing in the way — no door panels to clear — so it’s easy to move equipment and goods in and out.
What sizes of roll-up door containers can I get?
Aztec Container offers them in 10ft, 20ft, and 40ft lengths. The 20ft is the most common all-around size. On the 40ft units, you can choose how many roll-up doors you want — 1, 2, 3, or 4 — depending on whether you’d rather have one big compartment or several separate access points along the container.
Why would I want a 40ft container with multiple roll-up doors?
Multiple doors let you split one long container into separate sections, each with its own access point. That’s handy when different crews, trades, or product categories need their own space without digging past everyone else’s gear. A four-door 40ft unit basically gives you four compartments in a single footprint, which is great for busy operations.
How much can I actually fit inside?
A 20 Foot roll-up door container gives you roughly 1,165 cubic feet of usable space — about enough for the contents of a small house or a sizable load of equipment. A 40ft unit roughly doubles that. The interior of a 20ft measures about 19′ 8″ long, 7′ 8.5″ wide, and 7′ 10″ tall.
How is a roll-up door different from a standard cargo door?
Cargo doors are two big panels that swing outward on hinges, so you need open space in front of the container for them to clear. A roll-up door lifts vertically and tucks away overhead instead — no swing room needed. That gives you a clean, full-width opening and lets you park the container in tighter spots.
Can a forklift or pallet jack drive through the door?
Yes, that’s one of the main reasons people pick this style. Because the door rolls straight up and clears the full width of the opening, a forklift or pallet jack can roll in and out without maneuvering around swinging panels. It makes handling heavy or palletized loads a lot faster.
How secure are these containers?
Each one comes with a steel lockbox built into the locking system, which shields the padlock and makes tampering much harder. Pair that with the heavy-gauge steel walls and frame, and a roll up door container is a solid choice when security matters for what you’re storing.
What’s the flooring like inside?
The floors are marine-grade plywood about an inch thick, set on the steel cross-members of the frame. It’s built to handle heavy loads and constant foot, cart, and forklift traffic without wearing out quickly.
Can I rent a roll-up door container instead of buying one?
Yes. Sales are available nationwide, and rentals are available throughout California. Renting works well for temporary projects, while buying makes more sense for long-term or permanent storage. Reach out for a quote on either option.
Can I add a walk-in door too, or customize the container?
You can. A roll-up door handles equipment and goods, while a walk-in (man) door provides easy entry like a regular building door; many setups combine both. Aztec also offers modifications to tailor a container to your specific use, so ask about what you have in mind.
