20ft Flat Rack Container – Collapsible End Walls

When Cargo Will Not Fit Inside: The 20ft Flat Rack Container

Some loads simply refuse to go through a set of container doors. That is the entire reason the 20ft flat rack container exists. Instead of an enclosed box, you get a reinforced steel deck with end walls and nothing in between, so machinery, pipe, boats, transformers and steel sections can be craned straight down onto the platform and lashed in place.

Because the deck carries load rather than the side walls, flat racks are engineered for concentrated point loads that would damage a standard container floor. That makes them the default choice for project cargo and heavy-lift work, and it also makes them useful on land as a movable base for equipment that has to travel between sites.

Specifications at a Glance

• Base footprint: 20ft ISO platform, 20' x 8' external, so it moves on standard chassis
• Construction: heavy-duty steel frame with a timber deck integrated into the structure
• End walls: collapsible, allowing empty units to be stacked and repositioned economically
• Securing points: lashing rings along side rails, corner posts and deck for multi-directional restraint
• Handling: ISO corner castings plus forklift pockets on empty units
• Certification: built to ISO standards for intermodal interoperability
• Delivery: flat $500 to all 50 states, quoted by route after the order is confirmed

Out of Gauge Cargo and Other Uses for a Flat Rack

Anything wider, taller or heavier than a dry van will take is a candidate.

• Construction plant, tracked machines and agricultural implements
• Boats, hulls and marine equipment moving overland or by sea
• Steel sections, pipe bundles, cable drums and coiled product
• Transformers, generators and industrial process equipment
• Vehicles and rolling stock that need open-deck loading
• A relocatable working platform or base for site equipment

Loading, Lashing and Transport Planning

Plan the lift before the flat rack arrives. You will need crane or forklift capacity for the cargo, not just the container, and you should know where the load's weight bears on the deck so it is spread rather than concentrated on one point. Use the lashing rings in opposing pairs so the load is restrained fore, aft and laterally, and confirm any over-dimension permits with the carrier, since out of gauge freight is priced and routed differently from standard boxes.

If the load is longer than 20 feet, the 40ft cargo-worthy flat rack doubles the deck length, and the 20ft cargo-worthy flat rack is the used-grade equivalent of this unit. Related open-deck and specialty equipment is grouped under specialized containers and the 20ft container category, and you can see everything currently listed on the main container catalog.

Frequently Asked Questions

How is a flat rack different from an open top container?

An open top container has full side walls and end doors with a removable tarpaulin roof, so it suits cargo that is too tall but still fits within the width. A flat rack has no side walls at all, which is what allows over-width loads and side or overhead loading by crane. Choose by which dimension your cargo exceeds.

Can the end walls be folded down?

Yes. Collapsible end walls fold flat so empty racks stack compactly for return transport, which is a major cost saver in project logistics. Some loads are also easier to slide on with the walls down. Follow the manufacturer's procedure when folding and raising them, as the mechanisms are heavy and spring-loaded on many designs.

What weight can a 20ft flat rack carry?

Flat racks are rated for substantially heavier payloads than a standard dry container of the same length, which is why they are used for heavy-lift work. The exact maximum gross and payload figures are stamped on the unit's CSC plate, and you should work to those rather than a general figure. Contact us and we will confirm the plated ratings for the specific rack you are quoting.
