Types of Used Containers for Sale
Standard Containers
Our standard used containers for sale come in popular 20ft and 40ft sizes. The 20ft shipping container is ideal for residential storage or construction equipment. For larger requirements, 40ft shipping containers are suitable for commercial storage or extensive shipping needs.
High-Cube Containers
Need extra height? Choose high-cube containers for an additional 30cm of vertical space on top of standard units. This extra headroom proves invaluable for transporting goods, equipment, and materials that require additional ceiling clearance.
Refrigerated Containers (Reefers)
Our used refrigerated containers maintain precise temperature control between -20°C and +18°C for perishable goods. These specialised shipping containers for sale are valuable for food producers, event caterers, pharmaceutical storage, and seasonal businesses requiring temporary cold storage.
Flat-Rack Containers
When transporting oversized cargo presents challenges, our flat-rack shipping containers for sale provide the solution. These specialised units feature collapsible sides that accommodate awkwardly shaped items, heavy machinery, timber, or construction materials that won’t fit standard dimensions.
Side-Opening Containers
Side-opening shipping containers feature full-length access doors along one or both sides, providing more accessibility for large equipment and goods compared to standard end-door containers. They’re ideal for retail spaces, events and storage that needs to be accessed frequently.
Open-Top Containers
Ideal for oversized cargo or crane-loaded items, open-top shipping containers have removable roof sections that preserve their structural integrity. They come with a tarpaulin cover and securing bars to protect against weather during transit while offering flexibility for vertical loading.
Insulated Shipping Containers
Minimise heat exposure when transporting and storing sensitive items with our insulated containers. Featuring foam-filled walls, this type of container maintains a consistent ambient temperature for various goods.
Modified and Custom Containers
Transform a used shipping container into a bespoke solution with our modification services. We convert standard units into functional offices, workshops, or retail space.

Customer Testimonials
Storage Container Grades
Used B-Grade Containers
The best quality used containers for sale available at SEA Containers. Structurally sound, 100% watertight, and fully windproof. Once updated with a valid CSC plate, they’re ready to be put in action for transporting goods. B-grade containers may have minor dents or signs of repair work but are in good condition overall.
Refurbished C-Grade Containers
C-grade used containers are an economical option suited for farms, business storage, office sites, and more. While these used C-grade storage containers may display more considerable signs of wear and repair, they’re still guaranteed to be 100% wind and waterproof upon delivery.
What are Container Safety Convention (CSC) Certified Containers
The Container Safety Convention (CSC) is the internationally adopted health and safety criteria to ensure the safety of all those involved in handling shipping containers. Valid CSC plates are required for any shipping container used for ocean voyage transport.
Under the widely utilised Periodic Examination Scheme (PES), all new containers receive a CSC valid for five years. At the expiry of this period, used shipping containers can have their CSC extended by a maximum of 30 months from the inspection date.
SEA Containers’s B-grade used containers for sale can be fitted with CSC plates at a customer’s request. These are valid for a standard 12 months (longer periods can be requested but are subject to container condition).
