A one trip container is a near-new unit that has only been used once to transport cargo from its manufacturing location. It’s the highest quality option available, with minimal wear and a clean, dent-free exterior.
Yes. Seablox offers delivery across Ontario and can arrange nationwide transport. We use tilt-deck trucks or crane services to place containers directly on your site.
Absolutely. Our shipping container rentals are available for both short and long-term needs, with flexible contracts to match your project timeline.
Standard colours are typically beige, grey, or blue, but custom colours and branding are available upon request for sales and modification projects.
Yes, we can customize your shipping container after purchase; however, it is much more economical to complete modifications before delivery. When the container is still at our facility, we can produce upgrades more efficiently, access specialized tools and equipment, and avoid the added costs of transportation for return or on-site work. For the best value and fastest turnaround, we recommend finalizing all modifications before your container leaves our yard.
