Quick answer: Buying a storage container in the UAE: 20ft vs 40ft sizes, new (one-trip) vs used, modifications like doors, shelving, insulation and ventilation.
A steel storage container is the quickest way to add secure, weatherproof storage at a construction site, warehouse yard, farm, villa or shop in the UAE. It can be delivered in a day, needs no foundation in most cases and can be moved when you’re done. This guide explains which size to choose, new vs used containers, useful modifications and what to check before you buy.
Need it modified? We supply and convert storage containers with extra doors, shelving, insulation and lighting. See our modified steel containers.
20ft vs 40ft Storage Containers
| 20 ft | 40 ft | 40 ft High Cube | |
|---|---|---|---|
| External size (approx.) | 6.1 m x 2.4 m x 2.6 m | 12.2 m x 2.4 m x 2.6 m | 12.2 m x 2.4 m x 2.9 m |
| Floor area (approx.) | 14 m² | 28 m² | 28 m² |
| Best for | Site tools, villa or shop storage, small yards | Bulk materials, stock, furniture, equipment | Tall items, racking or conversion to offices |
| Delivery | Easier, fits smaller spaces | Needs more space and a larger truck | Same as 40 ft |
A 40 ft container gives double the space of a 20 ft one for much less than double the price, but you need room to deliver and place it. Measure your space, including access for the truck.
New (One-Trip) vs Used Containers
| New / one-trip | Used (cargo-worthy or wind and watertight) | |
|---|---|---|
| Condition | Like new, clean paint, minimal dents | Dents, rust spots and faded paint |
| Lifespan | Longest | Shorter, depends on condition |
| Best for | Long-term storage, conversions, visible locations | Site storage and budget use |
| Price | Higher | Lower |
What to Check Before You Buy a Used Container
- Roof: look for dents that hold water, rust holes and soft spots.
- Corners and base rails: heavy rust here weakens the whole container.
- Floor: marine plywood should be solid, not soft, delaminated or oil-soaked.
- Doors: they should open and close easily, with working locking bars and good rubber seals.
- Light test: stand inside with the doors closed. Any light coming in means a hole.
- Smell and residue: avoid containers that carried chemicals if you’ll store food or work inside.
The same approach works for cabins. See our used porta cabin checklist.
Useful Modifications
- Personnel door so you don’t need to open the cargo doors every time
- Roller shutter on the side for easy access to tools and stock
- Shelving and racking
- Insulation and AC for goods that can’t take UAE heat, such as paints, chemicals, electronics or documents
- Ventilation to stop condensation and smells
- Lighting and sockets
- Lockbox to protect the padlock from bolt cutters
- Paint and branding in company colours
With more work a container becomes a site office, a workshop or a shop. See shipping container conversion ideas and our container cafe guide.
Placing a Storage Container
Containers should sit on firm, level ground, ideally on concrete blocks or a strip at the corners, so the floor stays off wet ground and the doors close properly. In villa communities, malls and free zones, check whether you need permission from the landlord or community before delivery.
Buy, Rent or Convert?
Renting suits a few months of storage. If you need storage for a year or more, or across several projects, buying is usually cheaper, and the container keeps resale value. For buying vs renting cabins, see our buying vs renting guide.
