10 ft Raised Bunded Storage Container – 300mm Bund, Corten Steel, 12 Vents

A 10 ft raised bunded storage container – 300mm bund, Corten steel, 12 vents provides compliant, secondary containment for storing hazardous liquids, oils, fuels, and chemicals with enhanced ventilation to reduce condensation and fume buildup. For example, this unit is perfect for storing IBCs, drums, or chemical containers where both spill containment and air circulation are critical for safety and product integrity. However, unlike standard bunded containers with minimal ventilation, this unit features 12 purpose-built vents strategically placed to promote continuous airflow. As a result, you receive a fully compliant hazardous liquid storage solution that minimizes condensation risk and meets COSHH ventilation requirements. Learn about oil storage regulations from official HSE guidelines.

Why Choose a 12-Vent Bunded Container for Your Site?

Standard bunded containers often lack adequate ventilation for volatile or moisture-sensitive materials. In contrast, this unit features 12 vents that create continuous cross-flow ventilation, exhausting stale air and drawing in fresh air. Consequently, the raised 300mm bund provides a secondary containment capacity of approximately 1,100–1,300 litres – sufficient for 110% of a standard IBC (1,000L) plus 10% as required by regulations. Moreover, the Corten steel construction provides exceptional corrosion resistance without requiring painting. Thus, you gain both regulatory compliance and superior airflow. See bunded storage ideas on Pinterest for layout inspiration.

Key Features of This 10ft Raised Bunded Container

The 12 vents and 300mm raised bund are the defining features of this unit. For instance, the multiple top and bottom vents promote natural convection – warm, moisture-laden air rises and exits through upper vents while cooler, drier air enters through lower vents. Similarly, the 300mm raised bund floor (3mm Durbar steel) provides both secondary containment and an anti-slip walking surface. Furthermore, the 10ft length accommodates two IBCs side by side or up to 8 x 205L drums. Finally, the double doors with factory-fitted lockbox provide secure, tamper-resistant access. Check UK hazardous storage regulations before ordering.

Ventilation System – 12 Vents Explained

Shipping containers are naturally airtight, leading to condensation and fume buildup. For example, this unit features 12 passive vents – typically six per side or distributed across walls and roof. Likewise, each vent is triple-screened to prevent insect ingress while allowing continuous airflow. If you are storing volatile chemicals, this ventilation system helps prevent hazardous fume accumulation. The vents measure approximately 12″ x 12″ (300mm x 300mm) each, providing significant total airflow area.

Bund Capacity and Compliance

This unit is designed to meet UK oil storage and COSHH regulations. First, the 300mm raised bund creates a containment volume of approximately 1,100–1,300 litres – exceeding the 110% requirement for a single IBC. Second, the fully welded 3mm Durbar steel floor eliminates weak points where leaks could escape. Third, the raised design allows visual inspection of the bund area. Finally, the 12 vents ensure adequate air exchange for stored materials.

Corten Steel Durability for Outdoor Storage

Outdoor chemical storage demands weather-resistant materials. First, this container is manufactured from Corten steel (weathering steel grade S355J2W) that resists atmospheric corrosion and aggressive chemical environments. Second, the 2.5mm wall thickness provides structural strength for stacking and heavy loads. Third, the 3mm Durbar floor is fully welded and leak-tested. Finally, the self-weathering patina means no painting or ongoing maintenance is required.

What’s Included

First, every unit includes the 10ft x 8ft Corten steel container with 300mm raised bund floor (3mm Durbar). Second, 12 ventilation vents are factory-fitted (triple-screened). Third, lockable double doors with two locking bars and factory-fitted lockbox are included. Finally, 2 x forklift pockets at the front allow easy repositioning.

For instance, add a high-security padlock for enhanced security. Likewise, internal drum racks or shelving can be installed. Contact our bunded storage team for custom configurations.

Final Verdict

In summary, this 12-vent raised bunded container delivers compliant hazardous liquid storage with superior airflow for moisture-sensitive or volatile materials. As a result, site managers can store chemicals, oils, and fuels safely while minimizing condensation damage and fume buildup. Consequently, one chemical storage facility chose this 12-vent model specifically to prevent corrosion on stored drum lids – a common problem in poorly ventilated containers. Therefore, choose this 12-vent version if you need enhanced airflow for volatile or moisture-sensitive materials. If you require only basic storage for non-volatile liquids, our standard 4-vent bunded container offers a lower-cost alternative. If you need a larger unit for more IBCs, consider our 20ft raised bunded container. Thus, request a free quote with your delivery postcode and ventilation requirements today.
