Description
The 40ft Used Collapsible Flat Rack Container from Big Bear Containers is a heavy-duty, wind- and watertight steel unit engineered for secure, long-lasting performance.
This 40ft used collapsible flat rack container is a CSC-certified open-structure freight unit built from COR-TEN weathering steel, designed specifically for the transport and storage of oversized, heavy, or irregularly shaped cargo that cannot be loaded into a standard closed ISO container. Unlike a conventional dry freight container, a flat rack has no roof and no fixed side walls — the cargo sits on an open steel deck between two foldable end walls, allowing loading from the sides and top by crane, reach stacker, or side loader without the dimensional constraints of a doorway opening.
The collapsible end walls fold flat onto the deck when the unit is empty, allowing multiple flat racks to be nested and stacked as a single compact unit for return shipping and empty storage — significantly reducing the space and cost of repositioning empty flat racks compared to fixed-end alternatives. When erected, the end walls provide a rated height of 6ft 4in (1,955mm) above the floor deck. The floor is wooden construction, providing a stable load-bearing surface across the full 38.3ft internal length and 7.8ft width.
The unit carries a valid CSC plate, certifying it for continued international shipping use in its current condition. The maximum payload is 33,280 kg (73,352 lbs) — the maximum weight of cargo the unit is rated to carry. The maximum cargo weight figure of 39,140 kg (86,269 lbs) represents the maximum gross weight including tare — confirm exact weight definitions with Big Bear Containers before use in a regulated shipping context. Forklift pockets are fitted for yard and terminal handling. The unit is available resprayed in any RAL color on request — confirm color and lead time at time of order.
For guidance on flat rack container usage, lashing regulations, and cargo securing requirements, refer to the Bureau International des Containers standards reference.

Ideal Uses
The 40ft Used Collapsible Flat Rack Container is a versatile shipping container suited to a wide range of jobs, including:
- Secure on-site storage for homes and businesses
- Tools, equipment and seasonal inventory
- Job-site and warehouse overflow
- Long-term weatherproof storage
Construction & Durability
This 40ft flat rack uses cargo-worthy steel graded wind- and watertight over a welded steel underframe with cross-members on close centers, which is why the floor takes forklift traffic without deflecting. The roof is a single corrugated sheet — no seams across the span to leak.
Delivery & Site Preparation
The 40ft flat rack goes out on a free tilt-bed run with delivery windows confirmed ahead of the date. A 40ft-class unit needs roughly 100ft of straight approach for the truck to back in and tilt. Gravel over compacted base is the cheapest pad that actually works; bare soil will pull moisture and settle unevenly through a wet season.

Every unit is inspected before it ships and backed by our 30-day return policy.
