Abbreviated as FR cabinet. The frame cabinet removes the top and sidewall of the box on the basis of the ordinary cabinet. Its characteristic is that there is no top and sidewall of the box, and sometimes even the end wall is removed, leaving only the bottom plate and four corner columns, which play an important role in super-standard container transportation.

Frame containers mainly load goods: ultra-long, ultra-wide, ultra-high large machinery and equipment and heavy goods.

The carrier of the special cabinet itself is less, and the demand of the market is also small. The operation is difficult and the link is complex, and the whole transportation process needs to be confirmed by many links in order to undertake it. It is mainly necessary to confirm the container, price and space in advance. The price difference is very big, does not have the comparability. Many shipping companies do not provide special cabinets. Relatively speaking, the value of goods carried by special cabinets is generally higher.
