The best storage container is not automatically the biggest or cheapest unit. South African buyers should compare the required storage space, delivery access, new or used condition, corrosion protection, security, installation method and future relocation costs. If a crane truck cannot reach the final position, a flat-pack modular storage container may be a better fit than a conventional shipping container.
Start with the job, not the container
A homeowner clearing garage space, a contractor securing tools and a farmer storing equipment may all search for a “storage container”, but they do not need the same product.
Write down four things before requesting prices:
- What will be stored?
- How much usable floor space is needed?
- Can a large delivery vehicle reach and safely place a complete container?
- Will the unit remain in one place or move between sites?
These answers quickly narrow the options and prevent a cheap purchase from becoming an expensive delivery problem.
The main types of storage container
Used shipping containers
An ISO shipping container was designed to move freight. Used units are widely repurposed for storage because they are large, rigid and familiar. Their condition varies, however. A buyer should inspect the doors, seals, roof, floor, previous repairs and corrosion instead of relying only on labels such as “used” or “cargo worthy”. Delivery normally requires suitable truck access and mechanical placement.
New or one-trip shipping containers
A newer shipping container generally offers a cleaner condition and longer remaining service life than a heavily used unit, but it retains the same access and placement requirements. It is a strong choice when the buyer needs an ISO-format steel box, substantial internal length or intermodal compatibility.
Flat-pack modular storage containers
A flat-pack unit arrives as components and is assembled near its final position. This is useful for backyards, courtyards, farms, construction sites and other places where a complete shipping container or crane truck cannot reach.
MOCON manufactures compact modular units with an AZ150 Aluzinc steel shell, integrated base, birch-plywood floor, stainless-steel hardware, forklift pockets and lifting hooks. MOCON’s stated external sizes are 2.05 × 2.05 × 2.05 m and 2.96 × 2.05 × 2.05 m. See the MOCON product range and field assembly guide.
Garden and tool sheds
Garden sheds can be appropriate for light domestic storage. Compare panel construction, the included floor, door hardware, anchoring and the value of the items being stored. A low-cost shed and a purpose-built steel container are not equivalent products simply because both create outdoor space.
Seven checks before buying
1. Measure usable space
External dimensions tell you whether a unit fits the site. Internal dimensions, door opening and clear floor area tell you whether your shelves, tools or stock will fit. Ask the supplier for a dimensioned drawing rather than estimating from photographs.
2. Inspect the delivery route
Measure the narrowest gate, passage and turn. Look up for branches and power lines and down for soft ground, slopes, drains and septic infrastructure. Confirm who is responsible for access, offloading and final placement.
3. Confirm the base requirement
A storage unit needs a firm, level, well-drained position. The supplier should explain permitted supports and tolerances. An incorrect base can affect doors, water runoff and long-term performance.
4. Understand the material and coating
“Steel” alone is not a complete specification. Ask for the steel type, coating designation, panel thickness, cut-edge treatment, fastener material and maintenance instructions. AZ150 denotes an aluminium-zinc coated steel with a nominal total coating mass of 150 g/m²; the complete product design and environment still determine real-world life.
5. Review security as a system
Strong walls do not compensate for a weak lock, exposed hinge, poor anchoring or an isolated location. Match the lock, lighting, alarm, camera coverage and insurance to the value and risk of the contents. No responsible supplier should call an outdoor store “theft-proof”.
6. Compare the total installed cost
Include the unit, delivery, crane or offloading, foundations or supports, assembly, shelves, ventilation, electrical work, anchoring and future relocation. Compare like with like and ask whether VAT is included.
7. Check after-sales support
Ask who manufactured the unit, which parts are replaceable, what the warranty covers and who can assist with relocation or reassembly. A traceable supplier and clear documentation are worth more than an anonymous bargain listing.
Which option is best?
| Requirement | Usually worth considering |
|---|---|
| ISO freight use or very large storage volume | Shipping container |
| Complete unit can be placed by truck or crane | Shipping container or delivered modular unit |
| Narrow gate, backyard, courtyard or restricted-access site | Flat-pack modular container |
| Compact, lower-value domestic garden storage | Garden shed |
| New steel unit with compact footprint and future relocatability | MOCON modular container |
The right answer depends on the site. A shipping container is excellent at the job it was designed to do. A modular storage container solves a different problem: creating secure, reusable space where the logistics of a full-size freight container may be impractical.
Frequently asked questions
What sizes does MOCON offer?
MOCON currently lists two external sizes: 2,050 × 2,050 × 2,050 mm and 2,960 × 2,050 × 2,050 mm. Request current internal dimensions and a door-opening drawing before planning shelves or equipment.
Does a MOCON container need a crane for assembly?
MOCON’s assembly guide states that the flat-pack shell can be assembled by a two-person team without a crane. Site preparation and safe handling still need to follow MOCON’s instructions.
Can the assembled unit be moved?
MOCON provides forklift pockets and top lifting hooks. The company states that the unit can be moved with up to 1,500 kg inside. Confirm load distribution, lifting procedure and equipment capacity with MOCON before moving any loaded unit.
Is a modular container a shipping container?
No. MOCON is a modular storage product rather than an ISO freight container. Buyers who need marine transport, stacking or CSC certification should choose a product designed and certified for that purpose.
