Full guide: what is a flat rack shipping container?

While the standardized shipping container revolutionized global trade, there were always some cargoes left behind. Oversized or non-standard-shaped items posed a logistical nightmare. And that’s when flat rack containers came into play, a simple innovation with a rich history of tackling these challenges.

The exact origin of these containers is unclear, but their development likely paralleled the rise of the standard container in the mid-20th century. As shipping efficiency boomed, the need for solutions for project cargo became more obvious. Flat racks offered a way to leverage the existing container infrastructure for these unique items.

Early versions of these containers were likely basic adaptations of standard containers, with the sides simply removed. Over time, the design evolved, with two main variations emerging. We will talk about them further.

The widespread adoption of such containers coincided with the growth of international trade in bulky goods like machinery, vehicles, and prefabricated structures. These offered a secure and cost-effective way to move these items, further streamlining global commerce.

There are two primary configurations.

FIXED-END

This design features permanent end walls, providing a robust foundation for exceptionally heavy or bulky cargo.

COLLAPSIBLE

These containers offer the advantage of collapsible end walls, allowing for more efficient storage of empty units during return journeys.

​​Here’s a breakdown to help you pick the perfect container for your specific needs.

Flat Rack

It is ideal for extremely oversized or odd-shaped cargo that surpasses the limitations of both length and width in a standard container. Think of construction equipment, massive machinery, vehicles, and even long structures.

Advantages
Offers complete side access for easier loading and unloading of bulky items from any direction. Provides a sturdy base for heavy cargo due to its fixed or collapsible end walls.

Disadvantages
Generally more expensive than open top containers due to their increased structural complexity. May require additional securing measures for cargo that isn’t stable.

Open Top Container

This one is ideal for oversized cargo that primarily exceeds the height limitations of a standard container. This includes items like tall machinery, large spools of cable, or bulk materials like scrap metal or grain.

Advantages
More cost-effective option compared to flat racks. Offers some protection from the elements with its removable canvas top. Easier to stack empty containers for return journeys.

Disadvantages
Limited side access due to solid walls. Requires special lifting equipment for loading and unloading cargo from the top. Not suitable for very wide or oddly shaped cargo that can’t be secured within the container’s footprint.

Flat rack containers offer a versatile and secure solution for shipping oversized or oddly shaped cargo that wouldn’t fit within a standard container.
