Side opening shipping containers provide full-length access along the container side as well as standard end doors, making loading and access faster than a standard container. Side opening containers are commonly used for palletised goods, oversized items, workshops, and container conversions where frequent access is needed. Available in 20ft standard, 20ft high cube, and 40ft high cube sizes, side opening containers are built to ISO standards for secure, weatherproof storage and can be supplied CSC plated for export where required.
Side access reduces the main drawback of standard containers, which is having to unload from the front to reach goods stored at the rear.

| 40ft High Cube | 40ft × 8ft × 9ft 6in (12192mm × 2430mm × 2890mm) | 39ft 4in × 7ft 7in × 8ft 9in (12000mm × 2330mm × 2650mm) | ~5830kg | ~74.0m³ |
Side opening containers are typically heavier than standard containers due to additional steel reinforcement required to support the full-length door system.



Side opening containers retain the same core structure as standard ISO containers, including marine-grade Corten steel construction and secure end cargo doors. The key difference is the long-side bi-fold door system, which allows wide access for loading and retrieval.
Each unit is inspected prior to delivery to confirm:
Side opening containers are specialist units, so confirming layout and door configuration before order is important.
New one-trip units are manufactured overseas and used once during transit into the UK. They offer the longest service life, cleanest appearance, and best resale value. Minor surface marks or small dents from transport are normal and do not affect performance.
Used side opening containers are less common than standard used containers because many owners keep them long-term. When used stock is available, it is fully inspected to ensure structural integrity and reliable door operation.
All side opening containers are supplied wind and watertight, with a 5-year guarantee on new one-trip units and a 12-month guarantee on used containers.

We deliver side opening containers nationwide using HIAB or flatbed transport, depending on site access and offload requirements.
Delivery options include:
Side opening containers require one extra practical consideration: clearance along the long side if the side doors need to open fully once the container is positioned. Placement should be planned so the side opening is usable, not blocked by fencing, walls, or stored materials.

Side opening containers are commonly chosen where speed of access matters.
They are ideal for:
A side opening container often removes the need to “re-pack” the container to reach items stored at the back.
Typical buyers include:
Side opening containers are often selected as a base for conversions because they offer visibility and access that standard containers cannot.

Optional upgrades can be added to improve security, appearance, or functionality.
Available options include:
New one-trip side opening units commonly include lockboxes as standard unless stated otherwise.
If a bespoke conversion is required, side opening containers can also be modified with service hatches, counters, windows, and internal fit-outs.
Choosing the right side opening container comes down to access needs, container length, and how the unit will be loaded.
If full side access is not essential, a standard container may offer better value for general storage. For example, a 20ft one-trip container is often a simpler choice when access through end doors is sufficient.
