20ft Tunnel and Double Door Containers

Container Projects supplies specialised 20ft tunnel units to industrial, commercial, and retail sectors throughout the country. If your project requires a permanent storage asset, we offer competitive container sales from our national depots. For temporary requirements, our container hire service provides high-quality units with flexible rental terms. To receive a bespoke price for your site, request a container quote today. We manage the entire logistics process to ensure your unit is delivered and positioned correctly on your premises. A tunnel container, also known as a 20ft tunnel double-door unit, provides dual-end access, ideal for FIFO storage or partitioned use.

20ft tunnel container specifications

The double door configuration provides identical door sets at both 8ft ends. This design improves accessibility and makes it easier to load long items. These units are constructed from high-tensile Corten steel with 28mm marine plywood flooring. Use the responsive table below to verify the exact measurements for your site placement.

Tare is the weight of the empty container. Payload is the maximum cargo weight the unit can safely hold. For a 20ft tunnel unit, the tare is approximately 2350kg, and the payload is approximately 28130kg. These units offer roughly 32.8 cubic metres of space. If you require extra vertical clearance, we also supply high cube variants. For standard single-end access, view our 20ft general-purpose options.

Hire or buy

Container Projects assists customers in choosing between hire and purchase based on the project lifespan. Hire is an efficient choice for short-term events or construction projects where dual access simplifies site movements. Buying is recommended for permanent site installations or for those planning bespoke container conversions. We also offer a container buy-back service for customers who no longer require their units once a project concludes.

Condition grades and definitions

The grade of the container determines its price and aesthetic appearance. Container Projects supplies units in the following industry-standard conditions:

• One-trip: A container used once for cargo transport to the UK, typically appearing in near-new condition.
• wind and watertight: A condition grade ensuring the unit prevents weather ingress and protects contents from light and moisture.
• IICL: The International Institute of Container Lessors standards for high-quality repair and inspection, typically applied to younger used stock.

Delivery access, siting, and placement

Safe delivery depends on clear access for our container haulage vehicles. Container Projects uses hiab trucks equipped with onboard cranes to position units accurately.

• Vehicle space: A standard 20ft delivery vehicle requires a minimum width of 10ft and vertical clearance of 15ft.
• Ground surface: Place units on firm level ground such as concrete, tarmac, or compacted gravel. Uneven surfaces can cause the steel frame to twist, which prevents both sets of doors from sealing correctly.
• Obstructions: Check the area for overhead power cables and low branches that may interfere with the crane lift.

Security, condensation, and aftercare

Container Projects prioritises security for all units. Every tunnel container features factory-fitted lockboxes on both ends to protect padlocks from tampering. To manage moisture, we can apply Grafo-therm anti-condensation coating to the internal ceiling to absorb moisture. Aftercare involves regular lubrication of the eight door hinges and checking the rubber gaskets. For more technical details on container maintenance, visit our container dimensions page.

Export use and compliance

If you intend to use your container for international shipping, it must feature a valid CSC plate. A CSC plate is a safety approval plate required for international shipping under global transport conventions. Container Projects ensures that units destined for export meet all structural integrity requirements and carry valid certification. For further information, see our container types guide.
