40ft Containers
40ft shipping containers are the industry standard for large-scale storage and export in the UK, offering maximum internal capacity in a single unit. A 40ft container is typically chosen where space allows and higher volume storage is required, such as commercial yards, construction sites, logistics hubs, and conversion projects. Buyers usually choose between new one-trip containers for longevity or used wind and watertight containers for cost-effective bulk storage.
When secure storage or export capacity is needed at scale, the 40ft container remains the most widely used large-format option available in the UK.
Available Sizes, Dimensions & Capacity
| Size | External (L × W × H) | Internal (L × W × H) | Weight | Approx. Capacity |
|---|---|---|---|---|
| 40ft | 40ft × 8ft × 8ft 6in (12192mm × 2438mm × 2590mm) | 39ft 6in × 7ft 8in × 7ft 10in (12032mm × 2330mm × 2390mm) | ~3800kg | ~67.6m³ |
| 40ft High Cube | 40ft × 8ft × 9ft 6in (12192mm × 2438mm × 2896mm) | 39ft 6in × 7ft 8in × 8ft 10in (12032mm × 2330mm × 2690mm) | ~3900kg | ~76.3m³ |
A 40ft container offers more than double the internal volume of a 20ft container, making it suitable for bulk storage, palletised goods, or conversion projects where uninterrupted internal space is required. The high cube option adds approximately 320mm of extra internal height for improved stacking and airflow.
Build Quality & Construction
All 40ft shipping containers supplied by Bosh Boxes are manufactured from marine-grade Corten steel and designed for long-term outdoor use in demanding environments. Each unit features full-length double cargo doors with reinforced locking bars and a heavy-duty marine plywood floor suitable for high-load storage.
Containers can be supplied CSC plated for export where required and are inspected prior to delivery to confirm structural condition, door operation, and locking function.
New & Used 40ft Containers – What's the Difference?
New (One-Trip) 40ft Containers
New one-trip 40ft containers are manufactured overseas and used only once during transit into the UK. They offer the longest service life, best cosmetic condition, and highest resale value. Minor dents or scuffs from transport are normal and do not affect performance.
Used 40ft Containers
Used 40ft containers have previously been part of active shipping fleets and are professionally inspected before resale. Cosmetic wear and surface rust are common, but all units remain structurally sound and suitable for secure storage, site use, or conversions.
All 40ft containers are supplied wind and watertight, with a 5-year guarantee on new one-trip units and a 12-month guarantee on used containers.

Nationwide Delivery Across the UK
We deliver 40ft containers nationwide using HIAB or flatbed transport, depending on site access and offload requirements.
Delivery options include:
- HIAB delivery with crane offload
- Flatbed delivery with customer offload or forklift
Due to their length, 40ft containers require more space for delivery and positioning than smaller units. Access, turning space, ground conditions, overhead clearance, and drop direction are confirmed in advance to reduce the risk of aborted deliveries.

Who Uses 40ft Containers?
40ft containers are commonly used by:
- Construction and infrastructure projects requiring bulk secure storage
- Retailers and wholesalers storing palletised stock or seasonal overflow
- Businesses converting containers into offices, workshops, or bespoke units
- Exporters shipping goods overseas using CSC plated containers
The large internal footprint of a 40ft container makes it particularly suitable where uninterrupted storage space or conversion flexibility is required.
Optional Extras & Modifications
Optional upgrades are often added to improve security, usability, or suitability for long-term use.
Available options include:
- Lockboxes and anti-vandal security kits
- Custom repainting in RAL colours
- Insulation, racking, and internal lining
- Lighting kits and container electrics
These additions allow a standard 40ft container to be adapted for storage, operational, or conversion use.
Choosing the Right 40ft Container
Choosing the right 40ft container depends on intended use, site access, and how long the unit will remain in place. New one-trip containers are typically selected for long-term storage or conversion projects, while used containers provide a practical solution for budget-led bulk storage.
