They are frequently used in the transport, import and export of industrial parts and machinery, vehicles, construction materials, cement poles, steel beams, profiles and wooden logs, but rarely used in the construction of container homes & houses.
Flat rack containers may also be known as flat bed or platform containers. The two longest sides or walls that are formed of steel in general purpose or reefer containers are missing. They are characterized by the fact that they have no superstructure but instead have fixed or collapsible ends as well as lashing points for securing the cargo. The ends on this type of container, therefore, not only characterize the container but also define how they are packed, unpacked, stacked and stored.
Hence, in the industry, there are 3 types of flat rack container.
1. Flat racks with fixed ends
The image on the right shows a new flat-bed container with two fixed ends.
Flat beds generally come in standardized ISO container sizes that are 20 foot, 40 foot and 45 foot.
2. Flat racks with collapsible ends
The main benefit here is that they can be conveniently collapsed and stacked neatly and efficiently without taking up too much space in container yards or sea ports.
Again, they are specified and standardized in the same way as those with fixed ends and therefore, must have an container ISO code prior to export or distribution.
3. Flat racks with no ends
As such, they cannot be said to “contain” anything although they are extremely useful for dimensional, heavy or bulky cargo. As intermodal freight containers, they have numerous applications and are used where other types of shipping container are impractical or not fit for purpose.
