20-foot Flat Rack Shipping Container — Cargo-worthy
The 20-foot flat-rack shipping container is perfect for transporting freight that is too large, heavy, or awkward (out-of-gauge (OOG)) and will not fit in a standard shipping container. The 20-foot container size is a lower-capacity option that is still compatible with intermodal infrastructure, ships, trucks, and railcars designed for 20-foot boxes.
Price range: $3,300–$3,900. Available in Premium Condition or Standard Condition. Bulk and wholesale pricing is available — call for multi-unit discounts. Inventory is limited and availability varies by location. Delivery is quoted separately based on your delivery location.
The open sides of a flat-rack container make them perfect for transporting extra-large, awkwardly shaped, and heavy items (out-of-gauge (OOG)) that wouldn't fit in a standard enclosed container. Their length and width remain compatible with container ships, trains, and other transport equipment designed for 20-foot containers.
Loading Flat-Rack Shipping Containers
The open sides can make loading cargo such as piping and timber very efficient. With their open tops, flat-rack containers allow cargo to be top-loaded by crane, which can be faster and more efficient. Flat-rack containers can also support extremely heavy loads of up to around 45,000 lbs.
This flexible loading can require less specialized handling equipment and less time, resulting in flat-rack containers being more cost-effective for shipping OOG cargo. Flat-rack containers are versatile and can accommodate a broad range of cargo sizes, shapes, and weights.

What Cargo Vault Customers Say
From quote to delivery the communication was outstanding. They answered every question and the used container exceeded my expectations for the price.

Our pop-up shop container is a showstopper. The serving window and electrical package were perfectly installed. Customers love the design and so do we.

Ordered a 40ft high cube for our job site storage. Delivery was on time, the container was in perfect condition, and the team was professional throughout. Will definitely order again.
