40 ft Raised Bunded Storage Container – 300mm Bund, Corten Steel, 48 Vents_

This 40 ft raised bunded storage container – 300mm bund, Corten steel, 48 vents provides compliant secondary containment for large volumes of hazardous liquids, oils, fuels, and chemicals. For example, this unit holds up to 8 IBCs (1,000L each) or 32 x 205L drums. Therefore, you can store significant chemical inventory in a single, compliant container.

Why Choose This High-Capacity Bunded Container?

Smaller bunded containers (8ft or 10ft) limit your storage capacity. In contrast, this 40ft unit accommodates up to 8 IBCs, making it ideal for chemical distributors, industrial facilities, and large-scale operations. Consequently, the 300mm raised bund creates a containment volume of approximately 8,800 litres – sufficient for 110% of 8 IBCs (8,000L) plus 10% as regulations require. Moreover, the 48 vents provide exceptional airflow throughout this long container. Thus, you gain maximum storage density with superior ventilation.

Key Features of This 40ft Raised Bunded Container

The 300mm bund depth and 48 ventilation vents make this container stand out. For instance, the raised bund floor (3mm Durbar steel) provides both secondary containment and an anti-slip walking surface. Similarly, the 48 vents create continuous cross-flow ventilation along the entire 40ft length, exhausting stale air and drawing in fresh air. Furthermore, the Corten steel construction provides exceptional corrosion resistance without requiring painting. Finally, the lockable double doors with factory-fitted lockbox provide secure, tamper-resistant access.

48 Vents – Maximum Airflow for Large Volumes

Standard bunded containers have only 4-12 vents, which often proves inadequate for 40ft lengths. In contrast, this unit features 48 strategically placed vents (approximately 12 per long side, per end), creating continuous passive airflow. First, the triple-screened vents prevent insect ingress while allowing air to circulate freely. Second, the high vent count eliminates condensation hotspots that typically occur in unventilated corners of long containers. Third, passive ventilation requires no power or ongoing maintenance. Thus, your stored chemicals stay drier and safer than in poorly ventilated alternatives.

Bund Capacity and Regulatory Compliance

This container exceeds UK oil storage regulations for high-volume applications. For example, the 40ft floor area of approximately 26 square metres creates a bund capacity of about 8,800 litres. Likewise, the fully welded 3mm Durbar steel floor eliminates any weak points where leaks could escape. Furthermore, we include a bund inspection hatch for checking liquid levels and cleaning. If you store IBCs, drums, or chemical containers, this container meets Environment Agency requirements for secondary containment.

Corten Steel Durability for Chemical Storage

Chemical storage demands exceptional corrosion resistance. First, Corten steel (grade S355J2W) forms a stable, self-protecting rust patina over time. Second, this patina prevents deeper corrosion, even in aggressive chemical environments. Third, the steel requires no painting or ongoing maintenance. Finally, a typical Corten steel bunded container lasts 25+ years in outdoor conditions. Therefore, you can store hazardous chemicals without worrying about premature container failure.

What’s Included

First, every unit includes the 40ft Corten steel container with 300mm raised bunded floor (3mm Durbar). Second, 48 ventilation vents come factory-fitted (triple-screened). Third, lockable double doors with two locking bars and a factory-fitted lockbox are included. Fourth, a bund inspection hatch (100mm diameter, screw cap) provides access. Finally, 4 forklift pockets allow easy repositioning.

For instance, you can add a heavy-duty removable ramp for drum trolley access. Likewise, you can add internal drum racks or shelving for organized storage. Furthermore, you can upgrade to 400mm or 500mm bund depths for extra containment capacity. Contact our team for custom configurations.

Pros and Cons

Pros:

• 300mm raised bund (approx. 8,800 litre capacity – holds 8 IBCs + 10%)

• 48 ventilation vents (maximum airflow, reduces condensation)

• 3mm Durbar steel floor (anti-slip, fully welded, leak-tested)

• Corten steel construction (weathering, corrosion-resistant)

• 40ft length holds up to 8 IBCs or 32 x 205L drums

• Lockable double doors with factory-fitted lockbox

• Triple-screened vents prevent insect ingress

• Compliant with UK oil storage and COSHH regulations

Cons:

• 40ft length requires significant delivery space (110ft straight line clearance)

• Very heavy when empty (approx. 4,200 kg)

• Higher cost than smaller bunded units

• 48 vents require periodic inspection (ensure unobstructed)

Technical Specifications

Final Verdict

In summary, this 40ft raised bunded container delivers high-volume hazardous liquid storage with maximum ventilation for large-scale chemical operations. As a result, you can store up to 8 IBCs in a single, compliant container while the 48 vents eliminate condensation concerns. Consequently, one chemical distributor replaced multiple smaller bunded units with this 40ft model, reducing their storage footprint by 40% while improving ventilation. Therefore, choose this 48-vent version if you need maximum airflow for volatile chemicals or moisture-sensitive materials. If you store non-volatile liquids, our standard 12-vent bunded container offers lower cost. If you need a smaller footprint, consider our 10ft or 20ft raised bunded containers. Thus, request a free quote with your delivery postcode and bund depth requirements today.
