Not sure which container you need? Start with its intended use, then compare size, condition, access and fit-out. This guide explains common container types; check our shop for the products currently listed.
| Your requirement | Types to consider | Key question |
|---|---|---|
| General storage | Standard dry container | Will your items fit through the doors and inside the usable space? |
| Limited site space | 10ft or another compact container | Is there room for both placement and unloading? |
| More storage volume | 40ft container or high cube | Do you need extra length, extra height, or both? |
| Temperature-controlled goods | Refrigerated container (reefer) | Can the unit achieve your required temperature with suitable power? |
| Office or site workspace | Container office or fitted building | Which services and fit-out are included? |
| Access along the side | Side-opening container | Is there enough clearance to open the side doors? |
| Oversized or specialist cargo | Open-top or flat-rack container | What equipment and transport approvals does the load need? |
Size labels usually refer to nominal external length. Internal dimensions, door openings and usable space vary, especially in insulated or modified units.
| Size or format | Typical reason to consider it | What to check |
|---|---|---|
| 10ft | A compact storage option where space is limited. | Exact dimensions and origin: some units are purpose-built; others are cut down from larger containers. |
| 20ft | A common size for storage and cargo applications. | Internal length, door clearance, permitted load and delivery access. |
| 40ft | More length for larger storage or workspace requirements. | A larger placement area and suitable unloading access. |
| Standard height | A common nominal external height of 8ft 6in. | Actual internal height and door opening. |
| High cube | A common nominal external height of 9ft 6in, giving more height than standard. | Available overhead clearance and the actual usable height. |
These are common market types, not a statement that every type is stocked by Ian Wilson Containers. Availability and specifications are shown in individual listings.
Consider for: General storage or suitable dry cargo.
An enclosed container with cargo doors, typically at one end. It is not normally a temperature-controlled space.
Before choosing: Check doors, seals, floor and condition. Consider condensation and ventilation for moisture-sensitive items.
Consider for: Items or layouts that need more height.
A taller format rather than a different condition grade. It may also be dry, refrigerated or modified.
Before choosing: Confirm internal height and delivery clearances; added height does not establish a higher permitted payload.
Consider for: Loading or accessing items along the length.
Side doors provide an alternative to end-only access. Door configuration varies.
Before choosing: Confirm the opening dimensions and leave clearance for the doors to operate.
Consider for: Access from both ends.
Cargo doors at each end can help with loading and organising stored items.
Before choosing: Check whether both ends will remain accessible after placement.
Consider for: Goods requiring controlled temperatures.
An insulated container fitted with refrigeration equipment. Operating capability depends on the specific unit.
Before choosing: Check tested condition, temperature range, power supply and running costs. A non-operating reefer is not a working cold store.
Consider for: Reducing heat transfer where insulation is needed.
Insulation without working refrigeration does not actively maintain a set temperature.
Before choosing: Clarify whether cooling equipment is included and operational; allow for ventilation and condensation management.
Consider for: Cargo that needs loading from above.
A roof opening, commonly covered with a removable tarpaulin, allows overhead access.
Before choosing: Check lifting arrangements, cover condition and the cargo’s transport requirements.
Consider for: Heavy or oversized specialist cargo.
A platform-style unit with end structures and open sides, rather than an enclosed storage box.
Before choosing: Confirm load limits, securing arrangements and specialist handling requirements.
Consider for: A particular layout or access arrangement.
Containers altered with features such as additional doors, windows, partitions or other fit-out, depending on the listing.
Before choosing: Review exactly what is included. Modifications can affect structural behaviour and suitability for shipping.
Consider for: Workspace or a fitted container-based space.
Units with a specified layout and fit-out. Services, insulation and facilities are not the same across all products.
Before choosing: Check electrical and plumbing connections, site preparation, intended occupancy and any required approvals.
Container type and condition are separate decisions. A used container can be a standard, high cube or specialist unit. Read the specific condition description rather than relying on the label alone.
| Description | What it generally means | What it does not establish |
|---|---|---|
| New / one-trip | Check whether the listing means an unused container or a one-trip unit. A one-trip unit has typically made one cargo journey and may show handling marks. | The terms are not interchangeable. Confirm previous use and the actual condition before ordering. |
| Used | A container that has had previous service, with wear varying by unit. | A fixed level of quality, weather resistance or shipping suitability. |
| Wind and watertight (WWT) | Describes keeping wind and rain out when closed, subject to the unit’s actual condition. | Insulation, freedom from condensation, or shipping certification. |
| Cargo worthy | Describes a unit considered suitable for cargo service under relevant requirements. | Automatic acceptance by every carrier; check current survey and certification requirements. |
| As-is / repair required | The unit may have faults or require work. | Suitability for immediate storage, transport or occupancy without inspection and repairs. |
Check internal measurements, door openings and any space lost to insulation or fit-out.
Review the stated condition, photographs and included features. Ask whether photos show the actual unit or a representative example.
Check the base, drainage, vehicle access and unloading space. Discuss slopes, gates and overhead obstructions.
For fitted or refrigerated units, check the power supply, service connections and installation work needed.
Confirm site permissions with the relevant authority. For shipping, check current documentation and carrier requirements.
Confirm availability and review the full price, applicable taxes, delivery charges, estimated delivery arrangements, payment instructions and cancellation, return and refund terms before committing.
Send the intended use, approximate size, delivery postcode and any essential features. Include a product link if you already have a container in mind.
