20ft Flat Rack Shipping Container for Sale

A 20ft used flat rack container — also called a certified flat rack or open-top cargo platform — is a pre-owned steel unit you own outright, engineered for oversized or heavy cargo that will not fit in standard enclosed containers. Collapsible end walls and an open-top, open-side design allow loading of tall, wide, or awkwardly shaped items from above or the sides.

What can you haul on a flat rack? Machinery, vehicles, pipes, building materials, and industrial equipment that exceeds standard container dimensions. Constructed from heavy-duty Corten steel and certified for international shipping, each unit is structurally sound, wind and watertight at the end walls, and inspected with CSC certification for global transport compliance.

Ideal for marine shipping, rail transport, industrial staging, and on-site storage of bulky materials. The open-frame design is the defining advantage — no roof or side walls to limit cargo height or width. Units ship in stock for nationwide delivery, giving you secure steel storage on a timeline that matches project deadlines without waiting on custom lead times.
