(1) According to different uses

According to different uses, ordinary special containers can be divided into general special containers and special special containers.

(1) General purpose special container, also known as dry cargo container or general cargo container, refers to a fully enclosed container with rigid top, side walls, end walls and bottom walls, and at least one end wall with a door. General purpose containers are suitable for shipping most general cargo.

(2) Special special containers refer to ordinary or cargo containers with unique structures for the convenience of loading and unloading goods without passing through the end doors, or for special purposes such as ventilation, including ventilated containers, open-top containers, rack-mounted containers and platform containers .

(2) According to different structures

The structure of ordinary cargo containers includes inner column type, outer column type, folding type and thin shell type, etc., which can be divided into:

(1) Inner column special container

Its side column or end column is located in the side wall or end wall, the advantage is that the appearance is smooth, it is not easy to be damaged by oblique external force, and it is convenient to print the logo. Good, and can reduce the moisture loss rate of the goods, the box lining does not need to be removed when repairing and replacing the outer panel.

(2) Outer column special container

Its side column or end column is outside the side wall or end wall, so when it is subjected to external force, the outer plate is not easy to be damaged, and sometimes the inner lining plate can be omitted.

(3) Folding special container

Its main parts (referring to the side walls, end walls and top of the box) can be simply folded or disassembled. It can be easily reassembled for reuse. The advantage is that the volume of the box can be reduced during recycling and storage, and the economical effect of transportation can be improved. However, since the main components are connected by hinges, their strength is affected.

(4) Thin shell special container

Different from the general special container structure (the frame bears the load, the outer plate of the box and the frame are riveted or welded together), all the components form a rigid body, which is similar to the aircraft structure. The advantage is that it is light in weight, and its whole body can withstand the torsion force that occurs without causing permanent deformation, but the process requirements are high.
