20 ft Raised Bunded Storage Container – 300mm Bund, Corten Steel, 24 Vents_

This 20 ft raised bunded storage container – 300mm bund, Corten steel, 24 vents provides compliant, secondary containment for hazardous liquids, oils, fuels, and chemicals with enhanced ventilation to reduce condensation and fume buildup. For example, you can store IBCs, drums, or chemical containers safely inside this 20ft bunded unit. Therefore, this container meets strict environmental and safety regulations for hazardous material storage.

Why Choose a 24-Vent Bunded Container?

Standard bunded containers often lack adequate ventilation for volatile or moisture-sensitive materials. In contrast, this unit features 24 strategically placed vents that create continuous cross-flow ventilation. Consequently, the 300mm raised bund provides secondary containment capacity of approximately 1,800 litres – sufficient for 110% of two IBCs (2,000L) plus 10% as regulations require . Moreover, the Corten steel construction provides exceptional corrosion resistance without requiring painting. Thus, you gain both regulatory compliance and superior airflow.

Key Features of This 20ft Raised Bunded Container

The 24 vents and 300mm raised bund make this hazardous storage container stand out. For instance, the 24 passive vents (triple-screened) create continuous airflow that exhausts stale air and draws in fresh air, preventing fume accumulation. Similarly, the 300mm raised bund floor (3mm Durbar steel supergrip floor) provides both secondary containment and an anti-slip walking surface. Furthermore, the integrally bunded sump includes a removable floor for easy cleaning. Finally, the lockable double doors with lockable handles and a box lock cover provide secure, tamper-resistant access.

24 Vents – Maximum Airflow for Hazardous Storage

The 24 vents eliminate condensation and fume buildup concerns in this 20ft container. For example, the triple-screened vents prevent insect ingress while allowing air to circulate freely throughout the container. Likewise, the high vent count eliminates condensation hotspots that typically occur in unventilated corners. Furthermore, passive ventilation requires no power or ongoing maintenance. If you store volatile chemicals or moisture-sensitive materials, this 24-vent configuration provides exceptional safety.

300mm Bund – Secondary Spill Containment

The 300mm raised bund provides critical secondary containment for hazardous materials. For example, the bund capacity of approximately 1,800 litres exceeds the 110% requirement for two IBCs (2,000L total) plus 10% . Likewise, the full-height integrally bunded container design creates a complete spill containment system. Furthermore, the removable floor panels allow easy access for cleaning the bund area. If you store diesel, chemicals, or oils, this bunded floor ensures you contain any spills safely.

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.

20ft Dimensions – Compact Bunded Storage

The 20ft length makes this bunded container ideal for smaller hazardous storage applications. For example, the internal length of approximately 19ft 4in accommodates 2 IBCs or up to 8 x 205L drums . Likewise, the internal width provides ample space for safe movement. Furthermore, the container includes 2 x forklift pockets at the front and 2 x at the side for easy repositioning . If you need hazardous liquid storage in a compact footprint, this 20ft bunded container delivers.

What’s Included

First, every unit includes the 20ft Corten steel container with 300mm raised bunded floor (3mm Durbar steel). Second, 24 ventilation vents come factory-fitted (triple-screened). Third, lockable double doors with lockable handles and box lock cover provide security. Fourth, a removable floor panel allows access for cleaning the bund. Finally, forklift pockets (4) 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, we can upgrade to 400mm or 500mm bund depths for extra containment capacity . Contact our team for custom configurations.
